Data Infrastructures Protect Preserve Secure and Serve Information
  Various IT and Cloud Infrastructure Layers including Data Infrastructures

What This All Means

Data Infrastructures exist to protect, preserve, secure and serve information along with the applications and data they depend on. With more data being created at a faster rate, along with the size of data becoming larger, increased application functionality to transform data into information means more demands on data infrastructures and their underlying resources.

Software-Defined Data Infrastructure Essentials: Cloud, Converged, and Virtual Fundamental Server Storage I/O Tradecraft is for people who are currently involved with or looking to expand their knowledge and tradecraft skills (experience) of data infrastructures. Software-defined data centers (SDDC), software data infrastructures (SDI), software-defined data infrastructure (SDDI) and traditional data infrastructures are made up of software, hardware, services, and best practices and tools spanning servers, I/O networking, and storage from physical to software-defined virtual, container, and clouds. The role of data infrastructures is to enable and support information technology (IT) and organizational information applications.

Everything is not the same in business, organizations, IT, and in particular servers, storage, and I/O. This means that there are different audiences who will benefit from reading this book. Because everything and everybody is not the same when it comes to server and storage I/O along with associated IT environments and applications, different readers may want to focus on various sections or chapters of this book.

If you are looking to expand your knowledge into an adjacent area or to understand whats under the hood, from converged, hyper-converged to traditional data infrastructures topics, this book is for you. For experienced storage, server, and networking professionals, this book connects the dots as well as provides coverage of virtualization, cloud, and other convergence themes and topics.

This book is also for those who are new or need to learn more about data infrastructure, server, storage, I/O networking, hardware, software, and services. Another audience for this book is experienced IT professionals who are now responsible for or working with data infrastructure components, technologies, tools, and techniques.

Intel Xeon Scalable Processors SDDI and SDDC

server storage I/O data infrastructure trends

 

Recently Intel announced a new family of Xeon  Scalable Processors (aka Purely) that for some workloads Intel claims to be on average of 1.65x  faster than their predecessors. Note your real improvement will vary based on  workload, configuration, benchmark testing, type of processor, memory, and  many other server storage I/O performance considerations.

In  general the new Intel Xeon Scalable Processors enable legacy and software  defined data infrastructures (SDDI), along with software  defined data centers (SDDC), cloud and other environments to support expanding  workloads more efficiently as well as effectively (e.g. boosting productivity).

 

Data Infrastructures and workloads

 

Some  target application and environment workloads Intel is positioning these new  processors for includes among others:

  • Machine  Learning (ML), Artificial Intelligence (AI), advanced analytics, deep learning  and big data
  • Networking  including software defined network (SDN) and network function virtualization  (NFV)
  • Cloud  and Virtualization including Azure Stack, Docker and Kubernetes containers,  Hyper-V, KVM, OpenStack VMware vSphere, KVM among others
  • High  Performance Compute (HPC) and High Productivity Compute (e.g. the other HPC)
  • Storage  including legacy and emerging software defined storage software deployed as appliances,  systems or server less deployment modes.

 

Features  of the new Intel Xeon Scalable Processors include:

  • New  core micro architecture with interconnects and on die memory controllers
  • Sockets  (processors) scalable up to 28 cores
  • Improved  networking performance using Quick Assist and Data Plane Development Kit (DPDK)
  • Leverages Intel Quick Assist Technology for CPU offload  of compute intensive functions including I/O networking, security, AI, ML, big  data, analytics and storage functions. Functions that benefit from Quick Assist  include cryptography, encryption, authentication, cipher operations, digital  signatures, key exchange, loss less data compression and data footprint  reduction along with data at rest encryption (DARE).
  • Optane Non-Volatile Dual Inline Memory Module  (NVDIMM) for storage class memory (SCM) also referred to by some as Persistent  Memory (PM), not to be confused with Physical Machine (PM).
  • Supports  Advanced Vector Extensions 512  (AVX-512)  for HPC and other workloads
  • Optional Omni-Path Fabrics in addition to 1/10Gb Ethernet  among other I/O options
  • Six memory channels supporting up to 6TB of RDIMM  with multi socket systems
  • From  two to eight  sockets per node (system)
  • Systems  support PCIe 3.x (some supporting x4 based M.2 interconnects)

 

Note  that exact speeds, feeds, slots and watts will vary by specific server model  and vendor options. Also note that some server system solutions have two or  more nodes (e.g. two or more real servers) in a single package not to be  confused with two or more sockets per node (system or motherboard). Refer to the where to learn more section below for links to Intel benchmarks and other resources.

 

Software Defined Data Infrastructures, SDDC, SDX and SDDI

What  About Speeds and Feeds

Watch  for and check out the various Intel partners who have or will be announcing  their new server compute platforms based on Intel Xeon Scalable Processors.  Each of the different vendors will have various speeds and feeds options that  build on the fundamental Intel Xeon Scalable Processor capabilities.

 

For  example Dell EMC announced their 14G server platforms at the May 2017  Dell EMC World event with details to follow (e.g. after the Intel  announcements).

 

Some  things to keep in mind include the amount of DDR4 DRAM (or Optane NVDIMM) will  vary by vendors server platform configuration, motherboards, several sockets  and DIMM slots. Also keep in mind the differences between registered (e.g.  buffered RDIMM) that give good capacity and great performance, and load reduced  DIMM (LRDIMM) that have great capacity and ok performance.

 

Various nvme options

What  about NVMe

It's there as these systems like previous Intel models support NVMe devices via PCIe  3.x slots, and some vendor solutions also supporting M.2 x4 physical  interconnects as well.

Note that Broadcom formerly known as Avago and LSI recently  announced PCIe based RAID and adapter cards that support NVMe attached devices in addition to  SAS and SATA.

What  About Intel and Storage

In  case you have not connected the dots yet, the Intel Xeon Scalable Processor  based server (aka compute) systems are also a fundamental platform for storage  systems, services, solutions, appliances along with tin-wrapped software.

 

What  this means is that the Intel Xeon Scalable Processors based systems can be used  for deploying legacy as well as new and emerging software-defined storage  software solutions. This also means that the Intel platforms can be used to  support SDDC, SDDI, SDX, SDI as well as other forms of legacy and  software-defined data infrastructures along with cloud, virtual, container,  server less among other modes of deployment.

Moving  beyond server and compute platforms, there is another tie to storage as part of  this recent as well as other Intel announcements. Just a few weeks ago Intel announced  64 layer triple level cell (TLC) 3D NAND solutions positioned for the client  market (laptop, workstations, tablets, thin clients). Intel with that  announcement increased the traditional aerial density (e.g. bits per square  inch or cm) as well as boosting the number of layers (stacking more bits as  well).

 

The  net result is not only more bits per square inch, also more per cubic inch or  cm. This is all part of a continued evolution of NAND flash including from 2D  to 3D, MCL to TLC, 32 to 64 layer.  In  other words, NAND flash-based Solid State  Devices (SSDs) are very much still a relevant and continue to be enhanced  technology even with the emerging 3D XPoint and Optane (also available via Amazon in M.2) in the wings.

 

server memory evolution
  Via Intel and Micron (3D XPoint launch)

 

Keep in mind that NAND flash-based technologies were announced almost 20 years ago (1999), and are still evolving. 3D XPoint announced two years ago, along with other emerging storage class memories (SCM), non-volatile memory (NVM) and persistent memory (PM) devices are part of the future as is 3D NAND (among others). Speaking of 3D XPoint and Optane, Intel had announcements about that  in the past as well.

What This All Means

Some say the PC is dead and IMHO that depends on what you mean or define a PC as. For example if you refer to a PC generically to also include servers besides workstations or other devices, then they are alive. If however your view is that PCs are only workstations and client devices, then they are on the decline.

 

However if your view is that a PC is defined by the underlying processor such as Intel general purpose 64 bit x86 derivative (or descendent) then they are very much alive. Just as older generations of PCs leveraging general purpose Intel based x86 (and its predecessors) processors were deployed for many uses, so to are today's line of Xeon (among others) processors.

 

Even with the increase of ARM, GPU and other specialized processors, as well as ASIC and FPGAs for offloads, the role of general purpose processors continues to increase, as does the technology evolution around. Even with so called server less architectures, they still need underlying compute server platforms for running software, which also includes software defined storage, software defined networks, SDDC, SDDI, SDX, IoT among others.

 

Overall this is a good set of announcements by Intel and what we can also expect to be a flood of enhancements from their partners who will use the new  family of Intel Xeon Scalable Processors in their products to enable software defined data infrastructures (SDDI) and SDDC.

server storage I/O data infrastructure trends
Updated 6/29/17

 

European General Data Protection Regulation (GDPR) go into effect in a year on May 25 2018 are you ready?

 

What Is GDPR

If your initial response is that you are not in Europe and do not need to be concerned about GDPR you might want to step back and review that thought. While it is possible that some organizations may not be affected by GDPR in Europe directly, there might be indirect considerations. For example, GDPR, while focused on Europe, has ties to other initiatives in place or being planned for elsewhere in the world. Likewise unlike earlier regulatory compliance that tended to focus on specific industries such as healthcare (HIPPA and HITECH) or financial (SARBOX, Dodd/Frank among others), these new regulations can be more far-reaching.

Do you have or know of relevant GDPR information and resources? Feel free to add them via comments or send us an email, however please watch the spam and sales pitches as they will be moderated.

 

What This All Means

Now is the time to start planning, preparing for GDPR if you have not done so and need to, as well as becoming more generally aware of it and other initiatives. One of the key takeaways is that while the word compliance is involved, there is much more to GDPR than just compliance as we have seen in the part. With GDPR and other initiatives data protection becomes the focus including privacy, protect, preserve, secure, serve as well as manage, have insight, awareness along with associated reporting.

Who Will Be At Top Of Storage World Next Decade?

server storage I/O data infrastructure trends

 

Data storage regardless of if hardware, legacy, new, emerging, cloud service or various software defined storage (SDS) approaches are all fundamental resource components of data infrastructures along with compute server, I/O networking as well as management tools, techniques, processes and procedures.

Focus on Data Storage Present and Future Predictions

Drew Robb (@Robbdrew) has a good piece over at Enterprise Storage Forum looking at the past, present and future of who will rule the data storage world that includes several perspective predictions comments from myself as well as others. Some of the perspectives and predictions by others are more generic and technology trend and buzzword bingo focus which should not be a surprise. For example including the usual performance, Cloud and Object Storage, DPDK, RDMA/RoCE, Software-DefinedNVM/Flash/SSD, CI/HCI, NVMe among others.

 

Here are some excerpts from Drews piece along with my perspective and prediction comments of who may rule the data storage roost in a decade:

Amazon Web Services (AWS) – AWS includes cloud and object storage in the form of S3. However, there is more to storage than object and S3 with AWS also having Elastic File Services (EFS), Elastic Block Storage (EBS), database, message queue and on-instance storage, among others. for traditional, emerging and storage for the Internet of Things (IoT).

 

It is difficult to think of AWS not being a major player in a decade unless they totally screw up their execution in the future. Granted, some of their competitors might be working overtime putting pins and needles into Voodoo Dolls (perhaps bought via Amazon.com) while wishing for the demise of Amazon Web Services, just saying.

 

Voodoo Dolls via Amazon.com
  Voodoo Dolls and image via Amazon.com

 

Of course, Amazon and AWS could follow the likes of Sears (e.g. some may remember their catalog) and ignore the future ending up on the where are they now list. While talking about Amazon and AWS, one will have to wonder where Wall Mart will end up in a decade with or without a cloud of their own?

 

Microsoft – With Windows, Hyper-V and Azure (including Azure Stack), if there is any company in the industry outside of AWS or VMware that has quietly expanded its reach and positioning into storage, it is Microsoft, said Schulz.

 

Microsoft IMHO has many offerings and capabilities across different dimensions as well as playing fields. There is the installed base of Windows Servers (and desktops) that have the ability to leverage Software Defined Storage including Storage Spaces Direct (S2D), ReFS, cache and tiering among other features. In some ways I'm surprised by the number of people in the industry who are not aware of Microsoft's capabilities from S2D and the ability to configure CI as well as HCI (Hyper Converged Infrastructure) deployments, or of Hyper-V abilities, Azure Stack to Azure among others. On the other hand, I run into Microsoft people who are not aware of the full portfolio offerings or are just focused on Azure. Needless to say, there is a lot in the Microsoft storage related portfolio as well as bigger broader data infrastructure offerings.

NetApp – Schulz thinks NetApp has the staying power to stay among the leading lights of data storage. Assuming it remains as a freestanding company and does not get acquired, he said, NetApp has the potential of expanding its portfolio with some new acquisitions. “NetApp can continue their transformation from a company with a strong focus on selling one or two products to learning how to sell the complete portfolio with diversity,” said Schulz.

 

NetApp has been around and survived up to now including via various acquisitions, some of which have had mixed results vs. others. However assuming NetApp can continue to reinvent themselves, focusing on selling the entire solution portfolio vs. focus on specific products, along with good execution and some more acquisitions, they have the potential for being a top player through the next decade.

 

Dell EMC – Dell EMC is another stalwart Schulz thinks will manage to stay on top. “Given their size and focus, Dell EMC should continue to grow, assuming execution goes well,” he said.

There are some who I hear are or have predicted the demise of Dell EMC, granted some of those predicted the demise of Dell and or EMC years ago as well. Top companies can and have faded away over time, and while it is possible Dell EMC could be added to the where are they now list in the future, my bet is that at least while Michael Dell is still involved, they will be a top player through the next decade, unless they mess up on execution.

 

Cloud and software defined storage data infrastructure
Various Data Infrastructures and Resources involving Data Storage

 

Huawei – Huawei is one of the emerging giants from China that are steadily gobbling up market share. It is now a top provider in many categories of storage, and its rapid ascendancy is unlikely to stop anytime soon. “Keep an eye on Huawei, particularly outside of the U.S. where they are starting to hit their stride,” said Schulz.

In the US, you have to look or pay attention to see or hear what Huawei is doing involving data storage, however that is different in other parts of the world. For example, I see and hear more about them in Europe than in the US. Will Huawei do more in the US in the future? Good question, keep an eye on them.

 

VMware – A decade ago, Storage Networking World (SNW) was by far the biggest event in data storage. Everyone who was anyone attended this twice yearly event. And then suddenly, it lost its luster. A new forum known as VMworld had emerged and took precedence. That was just one of the indicators of the disruption caused by VMware. And Schulz expects the company to continue to be a major force in storage. “VMware will remain a dominant player, expanding its role with software-defined storage,” said Schulz.

VMware has a dominant role in data storage not just because of the relationship with Dell EMC, or because of VSAN which continues to gain in popularity, or the soon to be released VMware on AWS solution options among others. Sure all of those matters, however, keep in mind that VMware solutions also tie into and work with other legacies as well as software-defined storage solution, services as well as tools spanning block, file, object for virtual machines as well as containers.

 

"Someday soon, people are going to wake up like they did with VMware and AWS," said Schulz. "That’s when they will be asking 'When did Microsoft get into storage like this in such a big way.'"

 

What the above means is that some environments may not be paying attention to what AWS, Microsoft, VMware among others are doing, perhaps discounting them as the old or existing while focusing on new, emerging what ever is trendy in the news this week. On the other hand, some environments may see the solution offerings from those mentioned as not relevant to their specific needs, or capable of scaling to their requirements.

 

Keep in mind that it was not that long ago, just a few years that VMware entered the market with what by today's standard (e.g. VSAN and others) was a relatively small virtual storage appliance offering, not to mention many people discounted and ignored VMware as a practical storage solution provider. Things and technology change, not to mention there are different needs and solution requirements for various environments. While a solution may not be applicable today, give it some time, keep an eye on them to avoid being surprised asking the question, how and when did a particular vendor get into storage in such a big way.

 

Is Future Data Storage World All Cloud?

Perhaps someday everything involving data storage will be in or part of the cloud.

 

Does this mean everything is going to the cloud, or at least in the next ten years? IMHO the simple answer is no, even though I see more workloads, applications, and data residing in the cloud, there will also be an increase in hybrid deployments.

 

Note that those hybrids will span local and on-premise or on-site if you prefer, as well as across different clouds or service providers. Granted some environments are or will become all in on clouds, while others are or will become a hybrid or some variation. Also when it comes to clouds, do not be scared, be prepared. Also keep an eye on what is going on with containers, orchestration, management among other related areas involving persistent storage, a good example is Dell EMCcode RexRay among others.

Server Storage I/O resources
Various data storage focus areas along with data infrastructures.

 

What About Other Vendors, Solutions or Services?

In addition to those mentioned above, there are plenty of other existing, new and emerging vendors, solutions, and services to keep an eye on, look into, test and conduct a proof of concept (PoC) trial as part of being an informed data infrastructure and data storage shopper (or seller).

 

Keep in mind that component suppliers some of whom like Cisco also provides turnkey solutions that are also part of other vendors offerings (e.g. Dell EMC VxBlock, NetApp FlexPod among others), Broadcom (which includes Avago/LSI, Brocade Fibre Channel, among others), Intel (servers, I/O adapters, memory and SSDs), Mellanox, Micron, Samsung, Seagate and many others.

E8, Excelero, Elastifile (software defined storage), Enmotus (micro-tiering, read Server StorageIOlab report here), Everspin (persistent and storage class memories including NVDIMM), Hedvig (software defined storage), NooBaa, Nutanix, Pivot3, Rozo (software defined storage), WekaIO (scale out elastic software defined storage, read Server StorageIO report here).

 

Some other software defined management tools, services, solutions and components  I'm keeping an eye on, exploring, digging deeper into (or plan to) include Blue Medora, Datadog, Dell EMCcode and RexRay docker container storage volume management, Google, HPE, IBM Bluemix Cloud aka IBM Softlayer, Kubernetes, Mangstor, OpenStack, Oracle, Retrospect, Rubrix, Quest, Starwind, Solarwinds, Storpool, Turbonomic, Virtuozzo (software defined storage) among many others

 

What about those not mentioned? Good question, some of those I have mentioned in earlier Server StorageIO Update newsletters,  as well as many others mentioned in my new book "Software Defined Data Infrastructure Essentials" (CRC Press). Then there are those that once I hear something interesting from on a regular basis will get more frequent mentions as well. Of course, there is also a list to be done someday that is basically where are they now, e.g. those that have disappeared, or never lived up to their full hype and marketing (or technology) promises, let's leave that for another day.

What This All Means

It is safe to say that each new year will bring new trends, techniques, technologies, tools, features, functionality as well as solutions involving data storage as well as data infrastructures. This means a usual safe bet is to say that the current year is the most exciting and has the most new things than in the past when it comes to data infrastructures along with resources such as data storage. Keep in mind that there are many aspects to data infrastructures as well as storage all of which are evolving. Who Will Be At Top Of Storage World Next Decade? What say you?

server storage I/O trends

Broadcom aka Avago aka LSI announces SAS SATA NVMe Adapters with RAID

In case you missed it, Broadcom formerly known as Avago who bought the LSI adapter and RAID card business announced shipping new SAS, SATA and NVMe devices.

 

While SAS and SATA are well established continuing to be deployed for both HDD as well as flash SSD, NVMe continues to evolve with a bright future. Likewise, while there is a focus on software-defined storage (SDS), software defined data centers (SDDC) and software defined data infrastructures (SDDI) along with advanced parity RAID including erasure codes, object storage among other technologies, there is still a need for adapter cards including traditional RAID.

 

Keep in mind that while probably not meeting the definition of some software-defined aficionados, the many different variations, permutations along with derivatives of RAID from mirror and replication to basic parity to advanced erasure codes (some based on Reed Solomon aka RAID 2) rely on software. Granted, some of that software is run on regular primary server processors, some on packaged in silicon via ASICs or FPGAs, or System on Chips (SOC), RAID on Chip (RoC) as well as BIOS, firmware, drivers as well as management tools.

 

SAS, SATA and NVMe adapters

 

For some environments cards such as those announced by Broadcom are used in passthru mode effectively as adapters for attaching SAS, SATA and NVMe storage devices to servers. Those servers may be deployed as converged infrastructures (CI), hyper-converged infrastructures (HCI), Cluster or Cloud in Box (CiB) among other variations. To name names you might find the above (or in the not so distant future) in VMware vSAN or regular vSphere based environments, Microsoft Windows Server, Storage Spaces Direct (S2D) or Azure Stack, OpenStack among other deployments (check your vendors Hardware Compatibility Lists aka HCLs). In some cases these cards may be adapters in passthru mode, or using their RAID (support various by different software stacks). Meanwhile in other environments, the more traditional RAID features are still used spanning Windows to Linux among others.

 

Who Is Broadcom?

Some of you may know of Broadcom having been around for many years with a focus on networking related technologies. However some may not realize that Avago bought Broadcom and changed their name to Broadcom. Here is a history that includes more recent acquisitions such as Brocade, PLX, Emulex as well as LSI. Some of you may recall Avago buying LSI (the SAS, SATA, PCIe HBA, RAID and components) business not sold to NetApp as part of Engenio. Also recall that Avago sold the LSI flash SSD business unit to Seagate a couple of years ago as part of its streamlining. That's how we get to where we are at today with Broadcom aka formerly known as Avago who bought the LSI adapter and RAID business announcing new SAS, SATA, NVMe cards.

 

What Was Announced?

 

Broadcom has announced cards that are multi-protocol supporting Serial Attached SCSI (SAS), SATA/AHCI as well as NVM Express (NVMe) as basic adapters for attaching storage (HDD, SSD, storage systems) along with optional RAID as well as cache support. These cards can be used in application servers for traditional, as well as virtualized SDDC environments, as well as storage systems or appliances for software-defined storage among other uses. The basic functionality of these cards is to provide high performance (IOPs and other activity, as well as bandwidth) along with low latency combined with data protection as well as dense connectivity.

 

Specific features include:

  • Broadcom’s Tri-Mode SerDes Technology enables  the operation of NVMe, SAS or SATA devices in a single drive bay, allowing for  endless design flexibility.
  • Management software including LSI Storage Authority (LSA), StorCLI, HII  (UEFI)
  • Optional CacheVault(R) flash cache protection
  • Physical dimension Low Profile 6.127” x 2.712”
  • Host bus type x8 lane PCIe Express 3.1
  • Data transfer rates SAS-3 12Gbs; NVMe up to 8 GT/s PCIe Gen 3

Wait, Doesnt NVMe use PCIe

For those who are not familiar with NVMe and in particular U.2 aka SFF 8639 based devices, physically they look the same (almost) as a SAS device connector. The slight variation is if you look at a SAS drive, there is a small tab to prevent plugging into a SATA port (recall you can plug SATA into SAS. For SAS drives that tab is blank, however on the NVMe 8639 aka U.2 drives (below left) that tab has several connectors which are PCIe x4 (single or dual path).

 

What this means is that the PCIe x4 bus electrical signals are transferred via a connector, to backplane chassis to 8639 drive slot to the drive. Those same 8639 drive slots can also have a SAS SATA connection using their traditional connectors enabling a converged or hybrid drive slot so to speak. Learn more about NVMe here (If the Answer is NVMe, then what were and are the questions?) as well as at www.thenvmeplace.com.

Who Is This For?

These cards are applicable for general purpose IT and other data infrastructure environments in traditional servers among others uses. They are also applicable for systems builders, integrators and OEMs whom you may be buying your current systems from, or future ones.

Where to  Learn More

The following are additional resources to learn more about vSAN and related technologies.

What this  all means

Even as the industry continues to talk and move towards more software-defined focus, even for environments that are serverless, there is still need for hardware somewhere. These adapters are a good sign of the continued maturing cycle of NVMe to be well positioned into the next decade and beyond, while also being relevant today. Likewise, even though the future involves NVMe, there is a still a place for SAS along with SATA to coexist in many environments. For some environment there is a need for traditional RAID while for others simply the need for attachment of SAS, SATA and NVMe devices. Overall, a good set of updates, enhancements and new technology for today and tomorrow, now, when do I get some to play with? ;).

Collaborative support single contact between Microsoft and Dell EMC

Who Is This For

This announcement is  for any organization that is looking for an  on-premise, in your data center private or hybrid cloud turnkey solution  stack. This initial set of announcements can be for those looking to do a proof  of concept (PoC), advanced prototype,  support development test, DevOp or gain cloud-like elasticity, ease of use, rapid procurement and other experiences of public  cloud, on your terms and timeline. Naturally,  there is a strong affinity and seamless experience for those already using, or  planning to use Azure Public Cloud for Windows,  Linux, Containers and other workloads, applications,  and services.

What Does This Cost

Check with your Dell EMC representative  or partner for exact pricing which  varies for the size and configurations.  There are also various licensing models to take into consideration if you have Microsoft Enterprise  License Agreements (ELAs) that your Dell EMC representative  or business partner can address for you. Likewise being cloud based, there is also time usage-based  options to explore.

Where to learn more

What this  all means

The dust is starting to settle on last falls Dell EMC  integration, both of whom have long histories working with, and partnering  along with Microsoft on legacy, as well as virtual software-defined data centers (SDDC), software-defined data infrastructures  (SDDI), native, and hybrid clouds. Some may view the Dell EMC VMware relationship as a primary  focus, however, keep in mind that both Dell and EMC had worked with Microsoft long before VMware came into being. Likewise, Microsoft remains one of the most commonly  deployed operating systems on VMware-based  environments. Granted Dell EMC have a significant  focus on VMware, they both also sell, service and support many services for Microsoft-based solutions.

 

What about Cisco, HPE, Lenovo among others who have to announce or discussed their Microsoft  Azure Stack intentions? Good question, until we hear more about what those and  others are doing or planning, there is  not much more to do or discuss beyond speculating  for now. Another common question is if there is demand  for private and hybrid cloud, in fact,  some industry expert pundits have even said private,  or hybrid are dead which is interesting, how can something be dead if it is  just getting started. Likewise, it is  early to tell if Azure Stack will gain traction with various organizations,  some of whom may have tried or struggled with OpenStack among others.

 

Given a large number  of Microsoft Windows-based servers on VMware, OpenStack, Public cloud services  as well as other platforms, along with continued growing popularity of Azure,  having a solution such as Azure Stack provides an attractive option for many environments. That leads to the question  of if Azure Stack is essentially a replacement for Windows Servers or Hyper-V  and if only for Windows guest operating systems. At this point indeed, Windows  would be an attractive and comfortable option, however, given a large number  of Linux-based guests running on Hyper-V  as well as Azure Public, those are also primary candidates as are containers  and other services.

 

Overall, this is an excellent  and exciting move for both Microsoft  extending their public cloud software stack to be  deployed within data centers in a hybrid way, something that those  customers are familiar with doing. This  is a good example of hybrid being spanning public and private clouds, remote  and on-premise, as well as familiarity  and control of traditional procurement with the flexibility, elasticity experience  of clouds.

 

software defined data infrastructures SDDI and SDDC

 

Some will say that if OpenStack is struggling in many organizations  and being free open source, how Microsoft can have success with Azure Stack.  The answer could be that some organizations  have struggled with OpenStack while others have not due to lack of commercial  services and turnkey support. Having installed both OpenStack and Azure Stack  (as well as VMware among others), Azure Stack is at least the TP3 PoC is easy  to install, granted it is limited to one node,  unlike the production versions. Likewise,  there are easy to use appliance versions of OpenStack that are limited in  scale, as well as more involved installs that unlock full functionality.

 

OpenStack, Azure Stack, VMware and others have their places,  along, or supporting containers along with other tools. In some cases,  those technologies may exist in the same environment supporting different  workloads, as well as accessing various public clouds, after all, Hybrid is the  home run for many if not most legality IT environments.

Overall this is a good announcement from Dell EMC for those who are interested in, or should become more aware about Microsoft Azure Stack, Cloud along with hybrid clouds. Likewise look forward to hearing more about the solutions from others who will be supporting Azure Stack as well as other hybrid (and Virtual Private Clouds).

Azure Stack Technical Preview 3 (TP3) Overview Preview Review

Perhaps you are aware or use Microsoft Azure, how about  Azure Stack?

 

This is part one of a two-part series looking at Microsoft Azure Stack providing an overview, preview and review. Read part two here that looks at my experiences installing Microsoft Azure Stack Technical Preview 3 (TP3).

 

For those who are not aware, Azure Stack is a private on-premise  extension of the Azure public cloud environment. Azure Stack now in technical preview three (e.g. TP3), or  what you might also refer to as a beta (get the bits here).

 

In addition to being available via download as a preview, Microsoft is also working with vendors such as Cisco, Dell EMC, HPE, Lenovo and others who have announced Azure Stack support. Vendors such as Dell EMC have also made proof of concept kits available that you can buy including server with storage and software. Microsoft has also indicated that once launched for production versions scaling from a few to many nodes, that a single node proof of concept or development system will also remain available.

 

software defined data infrastructure SDDI and SDDC
Software-Defined Data Infrastructures (SDDI) aka Software-defined Data Centers, Cloud, Virtual and Legacy

 

Besides being an on-premise, private  cloud variant, Azure Stack is also hybrid capable being able to work with  public cloud Azure. In addition to working with public cloud Azure, Azure  Stack services and in particular workloads can also work with traditional  Microsoft, Linux and others. You can use pre built solutions from the Azure marketplace, in addition to developing your applications using Azure services and DevOps tools. Azure Stack enables hybrid deployment into public or private cloud to balance flexibility, control and your needs.

 

Azure Stack Overview

Microsoft Azure Stack is an on premise (e.g. in your own data center) private (or hybrid when connected to Azure) cloud platform. Currently Azure Stack is in Technical Preview 3 (e.g. TP3) and available as a proof of concept (POC) download from Microsoft. You can use Azure Stack TP3 as a POC for learning, demonstrating and trying features among other activities. Here is link to a Microsoft Video providing an overview of Azure Stack, and here is a good summary of roadmap, licensing and related items.

 

In summary, Microsoft Azure Stack is:

  • A onsite, on premise, in your data center extension of Microsoft Azure public cloud
  • Enabling private and hybrid cloud with strong integration along with common experiences with Azure
  • Adopt, deploy, leverage cloud on your terms and timeline choosing what works best for you
  • Common processes, tools, interfaces, management and user experiences
  • Leverage speed of deployment and configuration with a purpose-built integrate solution
  • Support existing and cloud native Windows, Linux, Container and other services
  • Available as a public preview via software download, as well as vendors offering solutions

What is Azure Stack Technical Preview 3 (TP3)

This version of Azure Stack is a single node running on a lone physical machine (PM) aka bare metal (BM). However can also be installed into a virtual machine (VM) using nesting. For example I have Azure Stack TP3 running nested on a VMware vSphere ESXi 6.5 systems with a Windows Server 2016 VM as its base operating system.

The TP3 POC Azure Stack is not intended for production environments, only for testing, evaluation, learning and demonstrations as part of its terms of use. This version of Azure Stack is associated with a single node identity such as Azure Active Directory (AAD) integrated with Azure, or Active Directory Federation Services (ADFS) for standalone modes. Note that since this is a single server deployment, it is not intended for performance, rather, for evaluating functionality, features, APIs and other activities. Learn more about Azure Stack TP3 details here (or click on image) including names of various virtual machines (VMs) as well as their roles.

Dell EMC World 2017 Day One news announcement summary

Recap of the first day of the first combined Dell EMC World 2017 being held in Las Vegas Nevada. Last year’s  event in Las Vegas was the end of the EMC World, while this being the first of the combined Dell EMC World events that succeeded its predecessors.

 

What this means is an expanded focus because of the new Dell  EMC that has added servers among other items to the event focus. Granted, EMC had been doing servers via its VCE and converged divisions, however with the Dell EMC integration completed as of last fall,  the Dell Server group is now part of the Dell EMC organization.

 

The central theme of  this Dell EMC world is REALIZE with a focus on four pillars:

  • Digital Transformation  (Pivotal focus) of applications
  • IT Transformation (Dell  EMC, Virtustream, VMware) data center modernization
  • Workforce transformation  (Dell Client Solutions) devices from mobile to IoT
  • Information Security (RSA  and Secureworks)

software defined data infrastructures SDDI and SDDC

What Did Dell EMC Announce

Note that while there are focus areas of the different Dell Technologies  business units aligned to the pillars, there is also leveraging across those  areas and groups. For example, VMware NSX spans into security, and  PowerEdge  servers span into other pillars as a core data infrastructure building block.

 

What Dell EMC and Dell Technologies announced today.

New 14th generation  PowerEdge Servers that are core building  blocks for data infrastructures

Dell EMC has announced  the 14th generation of Intel-powered Dell EMC PowerEdge server portfolio systems. These includes servers  that get defined with software for software-defined  data centers (SDDC), software-defined data infrastructures (SDDI) for the cloud, virtual, the container as well as storage among other applications. Target  application workloads and environments range from high-performance compute (HPC), and high-productivity (or profitability)  compute (the other HPC), super compute (SC), little data and big data analytics,  legacy and emerging business applications as well as cloud and beyond. Enhancements  besides new Intel processor technology includes enhanced iDRAC, OpenManage,  REST interface, QuickSync, Secure Boot among other management, automation,  security, performance, and capacity  updates.

 

Other Dell EMC enhancements with Gen14 include support for  various NVDIMM to enable persistent memory also known as storage class memories  such as 3D Xpoint among others. Note at  this time, Dell EMC is not saying much about speeds, feeds and other details,  stay tuned for more information on these in the weeks and months to come.

 

Dell EMC has also been leaders with deploying NVMe from PCIe flash cards to 8639 U.2 devices such as  2.5” drives. Thus it makes sense to see continued adoption and deployment of  those devices along with SAS, SATA support. Note that Broadcom (formerly known  as Avago) recently announced the release of their PCIe SAS, SATA and NVMe based  adapters.

 

The reason this is worth mentioning is that in the past Dell  has OEM sourced Avago (formerly known as LSI) based adapters. Given Dell EMC  use of NVMe drives, it only makes sense to put two and two together.

 

Let’s wait a few months to see what the speeds, feeds, and specifications are to put the rest  of the puzzle together. Speaking of NVMe, also look for Dell EMC to also supporting PCIe AIC and U.2 (8639) NVMe  devices, also leverage M.2 Next Generation Form Factor (NGFF) aka Gum sticks as  boot devices.

 

While these are all Intel focused, I would expect Dell EMC not to sit back, instead, watch for what they  do with other processors and servers including ARMs among others.

 

Increased support for more GPUs to support VDI and other  graphic intensive workloads such as video rendering, imaging among others. Part  of enhanced GPU support is improvements (multi-vector cooling) to power and cooling  including sensing the type of PCIe card, and then adjusting cooling fans and subsequent  power draw accordingly. The benefit should be more proper cooling to reduce power to support more work and productivity.

 

Flexible consumption models (financing and more) from desktop to data center

Dell Technologies has announced several financing, procurement, and consumption  models with cloud-like flexible options  for different IT and data center, along  with mobile device technologies.

These range from licensing to deployment as a  service, consumption and other options  via Dell Financial Services (DFS).

 

Highlights include:

  • DFS Flex on Demand is available now in select countries  globally.
  • DFS Cloud Flex for HCI is available now for Dell EMC VxRail  and Dell EMC XC Series and has planned availability for Q3 2017 in Dell EMC  VxRack Systems.

Data protection enhancement highlights include:  

  • New Turnkey Integrated  Data Protection Appliance (IDPA) with four models (DP5300, DP5800, DP8300, and DP8800) starting at 34 TB  usable scaling up to 1PB usable. Data services including encryption, data  footprint reduction such as dedupe, remote monitoring, Maintenance service dispatch, along with application integration.  Application integration includes MongoDB, Hadoop, MySQL.
       
  • Enhanced cloud capabilities  powered by Data Domain virtual edition (DD VE 3.1) along with data protection suite  enable data to be protected too, and  restored from Amazon Web Services (AWS) Simple Storage Service (S3) as well as  Microsoft Azure.
       

Open Networking and software-defined  networks (SDN) with 25G

  Dell EMC Open Networking highlights include:

  • Dell  EMCs first 25GbE open networking top of  rack (TOR) switch including S5100-ON  series (With OS10 enterprise edition software)  complimenting new PowerEdge Gen14 servers with native 25GbE support. Switches  support 100GbE uplinks fabric connectivity for east-west (management) network  traffic. Also announced is the S4100-ON  series and N1100-ON  series that are in addition to recently  announce N3100-ON and N2100-ON switches.
  • Dell EMCs first optimized  Open Networking platform for unified storage network switching including  support for 16Gb/32GB Fibre Channel
  • New Network Function Virtualization  (NFV) and IoT advisory consulting services

Note that Dell EMC is announcing the availability of these networking solutions in Dell Technologies  2018 fiscal year which occurs before the traditional calendar year.

Using Gen14 servers, several Software Defined Storage (SDS) enhancements

 

Dell EMC announced enhancements to their Software Defined  Storage (SDS) portfolio that leveraging  the PowerEdge 14th generation server portfolio. These improvements include ScaleIO, Elastic Cloud Storage (ECS), IsilonSD Edge and Preview of  Project Nautilus.

 

Where to learn more

What this  all means

This is a summary of what has been announced so far on the first  morning of the first day of the first new Dell EMC world. Needless to say, there is more detail to look at for the  above announcements from speeds, feeds, functionality and related topics that  will get addressed in subsequent posts. Overall this is a good set of announcements expanding capabilities of the  combined Dell EMC while enhancing existing systems as well as well as  solutions.

GDPR  goes into effect May 25 2018 Are You Ready?

The  new European General Data Protection  Regulation (GDPR) go into effect in a year on May  25 2018 are you ready?

 

Why  Become GDPR Aware

If your initial response is that you are not in Europe and do not need to be concerned about GDPR you might want to step back and review that thought.  While it is possible that some organizations may not be affected by GDPR in  Europe directly, there might be indirect considerations. For example, GDPR, while focused on Europe, has ties to other initiatives in place or being planned for elsewhere in the world. Likewise unlike earlier regulatory compliance that  tended to focus on specific industries such as healthcare (HIPPA and HITECH) or  financial (SARBOX, Dodd/Frank among others), these new regulations can be more  far-reaching.

 

GDPR  Looking Beyond Compliance

Taking a step back, GDPR, as its name implies, is about general data protection including how information is protected, preserved, secured and served. This also includes taking safeguards to logically protect data with passwords, encryption among other techniques. Another dimension of GDPR is reporting and ability to track  who has accessed what information (including when), as well as simply knowing  what data you have.

 

What this means is that GDPR impacts users from consumers of social media such as  Facebook, Instagram, Twitter, Linkedin among others, to cloud storage and related services, as well as traditional applications. In other words, GDPR is  not just for finance, healthcare, it is more far-reaching making sure you know  what data exists, and taking adequate steps to protect.

There is a lot more to discuss of GDPR in Europe as well as what else is being done in other parts of the world. For now being aware of initiatives such as GDPR and its broader scope impact besides traditional compliance is important. With these new initiatives, the focus expands from the compliance  office or officers to the data protection office and data protection officer  whose scope is to protect, preserve, secure and serve data along with associated  information.

 

GDPR  and Microsoft Environments

As  part of generating awareness and help planning, I’m going to be presenting  a free webinar produced by Redmond Magazine sponsored by Quest (who will also be  a co-presenter) on June 22, 2017 (7AM PT). The title of the webinar is GDPR Compliance Planning for Microsoft Environments.

 

This webinar looks at the General  Data Protection Regulation (GDPR) and its impact on Microsoft environments.  Specifically, we look at how GDPR along with other future compliance directives impact Microsoft cloud, on-premise, and hybrid environments, as well as what you can do to be ready before the May 25, 2018 deadline. Join us for this  discussion of what you need to know to plan and carry out a strategy to help  address GDPR compliance regulations for Microsoft environments.
   
  What you will learn during this discussion:

  • Why GDPR and other regulations  impact your environment
  • How to assess and find  compliance risks
  • How to discover who has access to  sensitive resources

This webinar applies to  business professionals responsible for strategy, planning and policy decision-making for Microsoft environments along with associated applications. This  includes security, compliance, data protection, system admins, architects and  other IT professionals.

 

What  This All Means

Now  is the time to start planning, preparing for GDPR if you have not done so and  need to, as well as becoming more generally aware of it and other initiatives.  One of the key takeaways is that while the word compliance is involved, there  is much more to GDPR than just compliance as we have seen in the part. With GDPR  and other initiatives data protection becomes the focus including privacy,  protect, preserve, secure, serve as well as manage, have insight, awareness along  with associated reporting. Join me and Quest on June 22, 2017 7AM PT for the  webinar GDPR Compliance Planning for Microsoft Environments to learn more.

 

Ok, nuff said, for now.

Part II Revisiting AWS S3 Storage Gateway (Test Drive Deployment)

This Amazon Web Service (AWS) Storage Gateway Revisited posts is a follow-up to the  AWS Storage Gateway test drive and review I did a few years ago (thus why it's called revisited). As part of a two-part series, the first post looks at what AWS Storage Gateway is, how it has improved since my last review of AWS Storage Gateway  along with deployment options. The second post in the series looks at a sample test drive deployment and use.

 

What About Storage Gateway Costs?

Costs vary by region, type of storage being used (files stored in S3, Volume Storage, EBS Snapshots, Virtual Tape storage, Virtual Tape storage archive), as well as type of gateway host, along with how access and used. Request pricing varies including data written to AWS storage by gateway (up to maximum of $125.00 per month), snapshot/volume delete, virtual tape delete, (prorate fee for deletes within 90 days of being archived), virtual tape archival, virtual tape retrieval. Note that there are also various data transfer fees that also vary by region and gateway host. Learn more about pricing here.

 

What Are Some Storage Gateway Alternatives

AWS and S3 storage gateway access alternatives include those from various third-party (including that are in the AWS marketplace), as well as via data protection tools (e.g. backup/restore, archive, snapshot, replication) and more commonly storage systems. Some tools include Cloudberry, S3FS, S3 motion, S3 Browser among many others.

 

Tip is when a vendor says they support S3, ask them if that is for their back-end (e.g. they can access and store data in S3), or front-end (e.g. they can be accessed by applications that speak S3 API). Also explore what format the application, tool or storage system stores data in AWS storage, for example, are files mapped one to one to S3 objects along with corresponding directory hierarchy, or are they stored in a save set or other entity.

 

AWS Storage Gateway Deployment and Management Tips

Once you have created your AWS account (if you did not already have one) and logging into the AWS console (note the link defaults to US East 1 Region), go to the AWS Services Dashboard and select Storage Gateway (or click here which goes to US East 1). You will be presented with three options (File, Volume or VTL) modes.

 

What Does Storage Gateway and Install Look Like

The following is what installing a AWS Storage Gateway for file and then volume looks like. First, access the AWS Storage Gateway main landing page (it might change by time you read this) to get started. Scroll down and click on the Get Started with AWS Storage Gateway button or click here.

 

AWS Storage Gateway Landing Page

Select type of gateway to create, in the following example File is chosen.

Select type of AWS storage gateway

 

Next select the type of file gateway host (EC2 cloud hosted, or on-premise VMware). If you choose VMware, an OVA will be downloaded (follow the onscreen instructions) that you deploy on your ESXi system or with vCenter. Note that there is a different VMware VM gateway OAV for File Gateway and another for Volume Gateway. In the following example VMware ESXi OVA is selected and downloaded, then accessed via VMware tools such as vSphere Web Client for deployment.

 

AWS Storage Gateway select download

 

Once your VMware OVA file is downloaded from AWS, install using your preferred VMware tool, in this case I used the vSphere Web Client.

 

AWS Storage Gateway VM deploy

 

Once you have deployed the VMware VM for File Storage Gateway, it is time to connect to the gateway using the IP address assigned (static or DHCP) for the VM. Note that you may need to allocate some extra VMware storage to the VM if prompted (this mainly applies to Volume Gateway). Also follow directions about setting NTP time, using paravirtual adapters, thick vs. thin provisioning along with IP settings. Also double-check to make sure your VM and host are set for high-performance power setting. Note that the default username is sguser and password is sgpassword for the gateway.

 

AWS Storage Gateway Connect

 

Once you successfully connect to the gateway, next step will be to configure file share settings.

 

AWS Storage Gateway Configure File Share

 

 

Configure file share by selecting which gateway to use (in case you have more than one), name of an S3 bucket name to create, type of storage (S3 Standard or IA), along with Access Management security controls.

 

AWS Storage Gateway Create Share

 

 

Next step is to complete file share creation, not the commands provided for Linux and Windows for accessing the file share.

 

AWS Storage Gateway Review Share Settings

 

 

Review file share settings

 

AWS Storage Gateway access from Windows

Now lets use the file share by accessing and mounting to a Windows system, then copy some files to the file share.

AWS Storage Gateway verify Bucket Items

 

Now let's go to the AWS console (or in our example use S3 Browser or your favorite tool) and look at the S3 bucket for the file share and see what is there. Note that each file is an object, and the objects simply appear as a file. If there were sub-directory those would also exist. Note that there are other buckets that I have masked out as we are only interested in the one named awsgwydemo that is configured using S3 Standard storage.

 

AWS Storage Gateway Volume

 

Now lets look at using the S3 Storage Gateway for Volumes. Similar to deploying for File Gateway, start out at the AWS Storage Gateway page and select Volume Gateway, then select what type of host (EC2 cloud, VMware or Hyper-V (2008 R2 or 2012) for on-premise deployment). Lets use the VMware Gateway, however as mentioned above, this is a different OVA/OVF than the File Gateway.

 

AWS Storage Gateway Configure Volume

 

Download the VMware OVA/OVF from AWS, and then install using your preferred VMware tools making sure to configure the gateway per instructions. Note that the Volume Gateway needs a couple of storage devices allocated to it. This means you will need to make sure that a SCSI adapter exists (or add one) to the VM, along with the disks (HDD or SSD) for local storage. Refer to AWS documentation about how to size, for my deployment I added a couple of small 80GB drives (you can choose to put on HDD or SSD including NVMe). Note that when connecting to the gateway if you get an error similar to below, make sure that you are in fact using the Volume Gateway and not mistakenly using the File Gateway OVA (VM). Note that the default username is sguser and password is sgpassword for the gateway.

 

AWS Storage Gateway Connect To Volume

 

Now connect to the local Volume Storage Gateway and notice the two local disks allocated to it.

 

AWS Storage Gateway Cached Volume Deploy

 

Next its time to create the Gateway which are deploying a Volume Cached below.

 

AWS Storage Gateway Volume Create

 

Next up is creating a volume, along with its security and access information.

 

AWS Storage Gateway Volume Settings

 

Volume configuration continued.

 

AWS Storage Gateway Volume CHAP

 

And now some additional configuration of the volume including iSCSI CHAP security.

 

AWS Storage Gateway Windows Access

 

Which leads us up to some Windows related volume access and configuration.

 

AWS Storage Gateway Using iSCSI Volume

 

Now lets use the new iSCSI based AWS Storage Gateway Volume. On the left you can see various WIndows command line activity, along with corresponding configuration information on the right.

 

AWS Storage Gateway Being Used by Windows

 

And there you have it, a quick tour of AWS Storage Gateway, granted there are more options that you can try yourself.

What This All Means

Overall I like the improvements that AWS has made to the Storage Gateway along with the different options it provides. Something to keep in mind is that if you are planning to use the AWS Storage Gateway File serving sharing mode that there are caveats to multiple concurrent writers to the same bucket. I would not be surprised if some other gateway or software based tool vendors tried to throw some fud towards the Storage Gateway, however ask them then how they coordinate multiple concurrent updates to a bucket while preserving data integrity.

 

Which Storage Gateway variant from AWS to use (e.g. File, Volume, VTL) depends on what your needs are, same with where the gateway is placed (Cloud hosted or on-premise with VMware or Hyper-V). Keep an eye on your costs, and more than just the storage space capacity. This means pay attention to your access and requests fees, as well as different service levels, along with data transfer fees.

 

You might wonder what about EFS and why you would want to use AWS Storage Gateway? Good question, at the time of this post EFS has evolved from being internal (e.g. within AWS and across regions) to having an external facing end-point however there is a catch. That catch which might have changed by time you read this is that the end-point can only be accessed from AWS Direct Connect locations.

 

This means that if your servers are not in a AWS Direct Connect location, without some creative configuration, EFS is not an option. Thus Storage Gateway File mode might be an option in place of EFS as well as using AWS storage access tools from others. For example I have some of my S3 buckets mounted on Linux systems using S3FS for doing rsync or other operations from local to cloud. In addition to S3FS, I also have various backup tools that place data into S3 buckets for backup, BC and DR as well as archiving.

 

Check out AWS Storage Gateway yourself and see what it can do or if it is a fit for your environment.

 

Ok, nuff said (for now...).

AWS S3 Storage Gateway Revisited (Part I)

This Amazon Web Service (AWS) Storage Gateway Revisited posts is a follow-up to the  AWS Storage Gateway test drive and review I did a few years ago (thus why it's called revisited). As part of a two-part series, the first post looks at what AWS Storage Gateway is, how it has improved since my last review of AWS Storage Gateway  along with deployment options. The second post in the series looks at a sample test drive deployment and use.

 

If you need an AWS primer and overview of various services such as Elastic Cloud Compute (EC2), Elastic Block Storage (EBS), Elastic File Service (EFS), Simple Storage Service (S3), Availability Zones (AZ), Regions and other items check this multi-part series (Cloud conversations: AWS EBS, Glacier and S3 overview (Part I) ).

 

AWS

 

As a quick refresher, S3 is the AWS bulk, high-capacity unstructured and object storage service along with its companion deep cold (e.g. inactive) Glacier. There are various S3 storage service classes including standard, reduced redundancy storage (RRS) along with infrequent access (IA) that have different availability durability, performance, service level and cost attributes.

 

Note that S3 IA is not Glacier as your data always remains on-line accessible while Glacier data can be off-line. AWS S3 can be accessed via its API, as well as via HTTP rest calls, AWS tools along with those from third-party's. Third party tools include NAS file access such as S3FS for Linux that  I use for my Ubuntu systems to mount S3 buckets and use similar to other mount points. Other tools include Cloudberry, S3 Motion, S3 Browser as well as plug-ins available in most data protection (backup, snapshot, archive) software tools and storage systems today.

 

AWS S3 Storage Gateway and What's New

The Storage Gateway is the AWS tool that you can use for accessing S3 buckets and objects via your block volume, NAS file or tape based applications. The Storage Gateway is intended to give S3 bucket and object access to on-premise applications and data infrastructures functions including data protection (backup/restore,  business continuance (BC), business resiliency (BR), disaster recovery (DR)  and archiving), along with storage tiering to cloud.

 

Some of the things that have evolved with the S3 Storage Gateway include:

  • Easier, streamlined download, installation, deployment
  • Enhanced Virtual Tape Library (VTL) and Virtual Tape support
  • File serving and sharing (not to be confused with Elastic File Services (EFS))
  • Ability to define your own bucket and associated parameters
  • Bucket options including Infrequent Access (IA) or standard
  • Options for AWS EC2 hosted, or on-premise VMware as well as Hyper-V  gateways (file only supports VMware and EC2)

AWS Storage Gateway Three Functions

AWS Storage Gateway can be  deployed for three basic functions:

 

AWS Storage Gateway File Architecture
AWS Storage Gateway File Architecture via AWS.com

    • File Gateway (NFS NAS) - Files, folders, objects and other  items are stored in AWS S3 with a local cache for low latency access to most  recently used data. With this option, you can create folders and subdirectory similar to a regular file system or NAS device as well as configure various security, permissions, access control policies. Data is stored in S3 buckets that you specify policies such as standard or Infrequent Access (IA) among other options. AWS hosted via EC2 as well as VMware Virtual Machine (VM) for on-premise file gateway.


      Also, note that AWS cautions on multiple concurrent writers to S3 buckets with Storage Gateway so check the AWS FAQs which may have changed by the time you read this. Current file share limits (subject to change) include 1 file gateway share per S3 bucket (e.g. a one to one mapping between file share and a bucket). There can be 10 file shares per gateway (e.g. multiple shares each with its own bucket per gateway) and a maximum file size of 5TB (same as maximum S3 object size). Note that you might hear about object storage systems supporting unlimited size objects which some may do, however generally there are some constraints either on their API front-end, or what is currently tested. View current AWS Storage Gateway resource and specification limits here.

AWS Storage Non-Cached e.g. Stored Volume Gateway Architecture
AWS Storage Gateway Non-Cached Volume Architecture via AWS.com

AWS Storage Gateway cached volume Architecture
  AWS Storage Gateway Cached Volume Architecture via AWS.com

    • Volume Gateway (Block iSCSI) - Leverages S3 with a point in  time backup as an AWS EBS snapshot. Two options exist including Cached volumes  with low-latency access to most recently used data (e.g. data is stored in AWS,  with a local cache copy on disk or SSD). The other option is Stored Volumes (e.g. non-cached) where primary  copy is local and periodic snapshot backups are sent to AWS. AWS provides EC2 hosted, as well as VMs for VMware and various Hyper-V Windows Server based VMs.


      Current Storage Gateway volume limits (subject to change) include maximum  size of a cached volume 32TB, maximum size of a stored volume 16TB. Note that snapshots of cached volumes larger than 16TB can only  be restored to a storage gateway volume, they can not be restored as an EBS  volume (via EC2). There are a maximum of 32 volumes for a gateway with total size of all volumes for a gateway (cached) of 1,024TB (e.g. 1PB). The total  size of all volumes for a gateway (stored volume)  is 512TB. View current AWS Storage Gateway resource and specification limits here.

AWS Storage Gateway VTL Architecture
  AWS Storage Gateway VTL Architecture via AWS.com

  • Virtual Tape Library Gateway (VTL) - Supports saving your data for  backup/BC/DR/archiving into S3 and Glacier storage tiers. Being a Virtual Tape Library (e.g. VTL) you can  specify emulation of tapes for compatibility with your existing backup,  archiving and data protection software, management tools and processes.


    Storage Gateway limits for tape include minimum size of a virtual tape 100GB, maximum size of a virtual tape 2.5TB, maximum number of virtual tapes for a VTL is 1,500 and total size  of all tapes in a VTL is 1PB. Note that the maximum number of virtual tapes in an archive is unlimited and total size of all tapes in an archive is also unlimited. View current AWS Storage Gateway resource and specification limits here.

What This All Means

As to which gateway function and mode (cached or non-cached for Volumes) depends on what it is that you are trying to do. Likewise choosing between EC2 (cloud hosted) or on-premise Hyper-V and VMware VMs depends on what your data infrastructure support requirements are. Overall I like the progress that AWS has put into evolving the Storage Gateway, granted it might not be applicable for all usage cases.

Microsoft Windows Server, Azure, Nano and life cycle Updates

Spoiler alert, Microsoft is refocusing Nano for containers only, no more Bare Metal...

 

For those of you who have an interest in Microsoft Windows  Server on-premise, on Azure, on Hyper-V or Nano life cycle here are some recently announced updates.
Microsoft Windows Server Nano Lifecycle

Microsoft has announced updates to Windows Server Core and Nano along with semi-annual channel updates (read more here). The synopsis of this new update via Microsoft (read more here) is:

In this new model, Windows Server releases are identified by  the year and month of release: for example, in 2017, a release in the 9th month  (September) would be identified as version 1709. Windows Server will release  semi-annually in fall and spring. Another release in March 2018 would be  version 1803. The support lifecycle for each release is 18 months.

Microsoft has announced that its lightweight variant of WIndows  Server 2016 (if you need a refresh on server requirements visit here) known as nano will now be focused for WIndows based containers as  opposed to being for bare metal. As part of this change, Microsoft has reiterated that Server Core the headless (aka non-desktop user interface)  version of WIndows Server 2016 will continue as the platform for BM along with other deployments where a GUI interface is not needed. Note that one of  the original premises of Nano was that it could be leveraged as a replacement  for Server Core.

 

As part of this shift, Microsoft has also stated their intention to further streamline the already slimmed down version of WIndows  Server known as Nano by reducing its size another 50%. Keep in mind that Nano is already a fraction of the footprint size of regular Windows Server (Core or  Desktop UI). The footprint of Nano includes both its capacity size on disk (HDD  or SSD), as well as its memory requirements, speed of startup boot, along with  number of components that cut the number of updates.

 

By focusing Nano for container use (e.g. Windows containers)  Microsoft is providing multiple micro services engines (e.g. Linux and  Windows) along with various management including Docker. Similar to providing  multiple container engines (e.g. Linux and Windows) Microsoft is also  supporting management from Windows along with Unix.

 

Does This Confirm Rumor FUD that Nano is Dead

IMHO the answer to the FUD rumors that are circulating around that NANO is dead are false.

 

Granted Nano is being refocused by Microsoft for containers and will not be the lightweight headless Windows Server 2016 replacement for Server Core. Instead, the Microsoft focus is two path with continued enhancements on Server Core for headless full Windows Server 2016 deployment, while Nano gets further streamlined for containers. This means that Nano is no longer bare metal or Hyper-V focused with Microsoft indicating that Server Core should be used for those types of deployments.

 

What is clear (besides no bare metal) is that Microsoft is working to slim down Nano even further by removing bare metal items, Powershell,.Net and other items instead of making those into optional items. The goal of Microsoft is to make the base Nano image on disk (or via pull) as small as possible with the initial goal of being 50% of its current uncompressed 1GB disk size. What this means is that if you need Powershell, you add it as a layer, need .Net then add as a layer instead of having the overhead of those items if you do not need tem. It will be interesting to see how much Microsoft is able to remove as standard components and make them options that you can simply add as layers if needed.

 

What About Azure and Bring Your Own License

In case you were not aware or had forgotten when you use Microsoft Azure and deploy virtual machine (aka cloud instances),  you have the option of bringing (e.g. using) your own WIndows Server licenses.  What this means is that by using your own Windows Server licenses you can cut the monthly cost of your Azure VMs. Check out the Azure site and explore  various configuration options to learn more about pricing and various virtual machine instances from Windows to Linux here as well as hybrid deployments.

 

Where To Learn More

What This All Means

Microsoft has refocused Windows Server 2016 Core and Desktop as its primary bare metal including for virtual as well as Azure OS platforms, while Nano is now focused on being optimized for Windows-based containers including Docker among other container orchestration.

Broadcom aka Avago aka LSI announces SAS SATA NVMe Adapters with RAID

In case you missed it, Broadcom formerly known as Avago who bought the LSI adapter and RAID card business announced shipping new SAS, SATA and NVMe devices.

 

While SAS and SATA are well established continuing to be deployed for both HDD as well as flash SSD, NVMe continues to evolve with a bright future. Likewise, while there is a focus on software-defined storage (SDS), software defined data centers (SDDC) and software defined data infrastructures (SDDI) along with advanced parity RAID including erasure codes, object storage among other technologies, there is still a need for adapter cards including traditional RAID.

 

Keep in mind that while probably not meeting the definition of some software-defined aficionados, the many different variations, permutations along with derivatives of RAID from mirror and replication to basic parity to advanced erasure codes (some based on Reed Solomon aka RAID 2) rely on software. Granted, some of that software is run on regular primary server processors, some on packaged in silicon via ASICs or FPGAs, or System on Chips (SOC), RAID on Chip (RoC) as well as BIOS, firmware, drivers as well as management tools.

SAS, SATA and NVMe adapters

 

For some environments cards such as those announced by Broadcom are used in passthru mode effectively as adapters for attaching SAS, SATA and NVMe storage devices to servers. Those servers may be deployed as converged infrastructures (CI), hyper-converged infrastructures (HCI), Cluster or Cloud in Box (CiB) among other variations. To name names you might find the above (or in the not so distant future) in VMware vSAN or regular vSphere based environments, Microsoft Windows Server, Storage Spaces Direct (S2D) or Azure Stack, OpenStack among other deployments (check your vendors Hardware Compatibility Lists aka HCLs). In some cases these cards may be adapters in passthru mode, or using their RAID (support various by different software stacks). Meanwhile in other environments, the more traditional RAID features are still used spanning Windows to Linux among others.

Who Is Broadcom?

Some of you may know of Broadcom having been around for many years with a focus on networking related technologies. However some may not realize that Avago bought Broadcom and changed their name to Broadcom. Here is a history that includes more recent acquisitions such as Brocade, PLX, Emulex as well as LSI. Some of you may recall Avago buying LSI (the SAS, SATA, PCIe HBA, RAID and components) business not sold to NetApp as part of Engenio. Also recall that Avago sold the LSI flash SSD business unit to Seagate a couple of years ago as part of its streamlining. That's how we get to where we are at today with Broadcom aka formerly known as Avago who bought the LSI adapter and RAID business announcing new SAS, SATA, NVMe cards.

What Was Announced?

Broadcom has announced cards that are multi-protocol supporting Serial Attached SCSI (SAS), SATA/AHCI as well as NVM Express (NVMe) as basic adapters for attaching storage (HDD, SSD, storage systems) along with optional RAID as well as cache support. These cards can be used in application servers for traditional, as well as virtualized SDDC environments, as well as storage systems or appliances for software-defined storage among other uses. The basic functionality of these cards is to provide high performance (IOPs and other activity, as well as bandwidth) along with low latency combined with data protection as well as dense connectivity.

 

Specific features include:

  • Broadcom’s Tri-Mode SerDes Technology enables  the operation of NVMe, SAS or SATA devices in a single drive bay, allowing for  endless design flexibility.
  • Management software including LSI Storage Authority (LSA), StorCLI, HII  (UEFI)
  • Optional CacheVault(R) flash cache protection
  • Physical dimension Low Profile 6.127” x 2.712”
  • Host bus type x8 lane PCIe Express 3.1
  • Data transfer rates SAS-3 12Gbs; NVMe up to 8 GT/s PCIe Gen 3
  • Various OS and hypervisors host platform support
  • Warranty 3 yrs, free 5x8 phone support, advanced replacement option
  • RAID levels 0, 1, 5, 6, 10, 50, and 60

 

Note that some of the specific feature functionality may be available at a later date, check with your preferred vendors HCL

Wait, Doesnt NVMe use PCIe

For those who are not familiar with NVMe and in particular U.2 aka SFF 8639 based devices, physically they look the same (almost) as a SAS device connector. The slight variation is if you look at a SAS drive, there is a small tab to prevent plugging into a SATA port (recall you can plug SATA into SAS. For SAS drives that tab is blank, however on the NVMe 8639 aka U.2 drives (below left) that tab has several connectors which are PCIe x4 (single or dual path).

 

What this means is that the PCIe x4 bus electrical signals are transferred via a connector, to backplane chassis to 8639 drive slot to the drive. Those same 8639 drive slots can also have a SAS SATA connection using their traditional connectors enabling a converged or hybrid drive slot so to speak. Learn more about NVMe here (If the Answer is NVMe, then what were and are the questions?) as well as at www.thenvmeplace.com.

Who Is This For?

These cards are applicable for general purpose IT and other data infrastructure environments in traditional servers among others uses. They are also applicable for systems builders, integrators and OEMs whom you may be buying your current systems from, or future ones.

 

Where to  Learn More

The following are additional resources to learn more about vSAN and related technologies.

What this  all means

Even as the industry continues to talk and move towards more software-defined focus, even for environments that are serverless, there is still need for hardware somewhere. These adapters are a good sign of the continued maturing cycle of NVMe to be well positioned into the next decade and beyond, while also being relevant today. Likewise, even though the future involves NVMe, there is a still a place for SAS along with SATA to coexist in many environments. For some environment there is a need for traditional RAID while for others simply the need for attachment of SAS, SATA and NVMe devices. Overall, a good set of updates, enhancements and new technology for today and tomorrow, now, when do I get some to play with? ;).

 

Ok, nuff said (for now...).

Who Is This For

This announcement is  for any organization that is looking for an  on-premise, in your data center private or hybrid cloud turnkey solution  stack. This initial set of announcements can be for those looking to do a proof  of concept (PoC), advanced prototype,  support development test, DevOp or gain cloud-like elasticity, ease of use, rapid procurement and other experiences of public  cloud, on your terms and timeline. Naturally,  there is a strong affinity and seamless experience for those already using, or  planning to use Azure Public Cloud for Windows,  Linux, Containers and other workloads, applications,  and services.

What Does This Cost

Check with your Dell EMC representative  or partner for exact pricing which  varies for the size and configurations.  There are also various licensing models to take into consideration if you have Microsoft Enterprise  License Agreements (ELAs) that your Dell EMC representative  or business partner can address for you. Likewise being cloud based, there is also time usage-based  options to explore.

Where to learn more

What this  all means

The dust is starting to settle on last falls Dell EMC  integration, both of whom have long histories working with, and partnering  along with Microsoft on legacy, as well as virtual software-defined data centers (SDDC), software-defined data infrastructures  (SDDI), native, and hybrid clouds. Some may view the Dell EMC VMware relationship as a primary  focus, however, keep in mind that both Dell and EMC had worked with Microsoft long before VMware came into being. Likewise, Microsoft remains one of the most commonly  deployed operating systems on VMware-based  environments. Granted Dell EMC have a significant  focus on VMware, they both also sell, service and support many services for Microsoft-based solutions.

 

What about Cisco, HPE, Lenovo among others who have to announce or discussed their Microsoft  Azure Stack intentions? Good question, until we hear more about what those and  others are doing or planning, there is  not much more to do or discuss beyond speculating  for now. Another common question is if there is demand  for private and hybrid cloud, in fact,  some industry expert pundits have even said private,  or hybrid are dead which is interesting, how can something be dead if it is  just getting started. Likewise, it is  early to tell if Azure Stack will gain traction with various organizations,  some of whom may have tried or struggled with OpenStack among others.

 

Given a large number  of Microsoft Windows-based servers on VMware, OpenStack, Public cloud services  as well as other platforms, along with continued growing popularity of Azure,  having a solution such as Azure Stack provides an attractive option for many environments. That leads to the question  of if Azure Stack is essentially a replacement for Windows Servers or Hyper-V  and if only for Windows guest operating systems. At this point indeed, Windows  would be an attractive and comfortable option, however, given a large number  of Linux-based guests running on Hyper-V  as well as Azure Public, those are also primary candidates as are containers  and other services.

 

Overall, this is an excellent  and exciting move for both Microsoft  extending their public cloud software stack to be  deployed within data centers in a hybrid way, something that those  customers are familiar with doing. This  is a good example of hybrid being spanning public and private clouds, remote  and on-premise, as well as familiarity  and control of traditional procurement with the flexibility, elasticity experience  of clouds.

software defined data infrastructures SDDI and SDDC

 

Some will say that if OpenStack is struggling in many organizations  and being free open source, how Microsoft can have success with Azure Stack.  The answer could be that some organizations  have struggled with OpenStack while others have not due to lack of commercial  services and turnkey support. Having installed both OpenStack and Azure Stack  (as well as VMware among others), Azure Stack is at least the TP3 PoC is easy  to install, granted it is limited to one node,  unlike the production versions. Likewise,  there are easy to use appliance versions of OpenStack that are limited in  scale, as well as more involved installs that unlock full functionality.

 

OpenStack, Azure Stack, VMware and others have their places,  along, or supporting containers along with other tools. In some cases,  those technologies may exist in the same environment supporting different  workloads, as well as accessing various public clouds, after all, Hybrid is the  home run for many if not most legality IT environments.

 

Overall this is a good announcement from Dell EMC for those who are interested in, or should become more aware about Microsoft Azure Stack, Cloud along with hybrid clouds. Likewise look forward to hearing more about the solutions from others who will be supporting Azure Stack as well as other hybrid (and Virtual Private Clouds).
