From the editors Virtual Desk

Well I had the best week. I have to admit I was a bit nervous about the launch being that it was going to be hosted as a virtual event and that there would be thousands in attendance. My job on launch day was to host a “virtual booth” which represented our management solutions. I really did not know what to expect but as it turns out is was the most awesome day. I interacted on virtual chat either in group chat or private chat with so many of our customers who were really just so keen to chat about the upcoming technology that we had announced. The enthusiasm and participation rate was amazing and by the end of my shift which lasted around 3 hours I was actually quite exhausted from all of the interaction but so impressed and excited all the same.


So on Wednesday night I decided to do the upgrade in my home lab. I know that there are many of you on the Beta programs who are wondering why it has taken me so long and I really have no excuse for this but fortunately I made the effort on Wednesday and for the past 2 days I have been running vSphere 5. I am not going to give too much away at this stage with just a few days in but suffice to say, it is awesome.


This week’s newsletter is a big one and I have tried to add as much content as possible following the launch of vSphere 5 and related technologies for you to serve as a reference. I have broken the newsletter up into a number of sections with the vSphere 5 related content towards the beginning of the newsletter to try and help as much as I can.


I hope that you enjoy all that is good about this amazing announcement and wish you well on your learnings towards vSphere 5.


I will let the bloggers tell you more so onwards to this week’s newsletter.


Take care until next time.

Rethink IT: Understanding the vSphere 5 vRAM Licensing Model

VMware Blogs

With the Cloud Infrastructure Launch on July 12 we announced changes to the vSphere 5 licensing model. vSphere 5 will continue to be licensed per physical processor with a new vRAM entitlement pooled across the entire environment.

We're monitoring the feedback very closely, we take it to heart, and we do want to do the right thing for our customers.  In this post, I’d like to point out a couple of things that may have gotten lost in the discussions, share with you some of the thinking behind the vSphere 5 licensing model, and point you to a tool can help you assess what these changes will mean to you. 

We are noticing a critical misconception that is permeating many of the discussions around the changes we’ve made.  I’d like to clarify:  the new licensing model is NOT based on physical RAM.  It is based on the amount of virtual RAM (vRAM) configured to a virtual machine. We have seen a lot of instances where people are trying to calculate the number of vSphere 5 licenses needed by taking the physical RAM in a server and dividing it by the vRAM entitlement for a particular vSphere edition.   That isn’t quite how the new model works.

The vSphere 5 licensing model has a pooled vRAM entitlement. vRAM is total amount of virtual RAM allocated to all VMs, and it is important to note that the total allocated vRAM for most customers is substantially smaller than the available physical RAM.  Most customers reserve at least 20% of spare physical RAM capacity that is not allocated as vRAM. 

To really get an understanding of how many vSphere 5 licenses a customer needs, you need to sum up the total amount of vRAM allocated in all powered-on VMs, and divide that total amount by the entitlement for the particular vSphere 5 edition you are running.  Let’s look at an example: if you have 100 VMs with 4GB of vRAM each, then you need a vRAM pool of 400GB. If you are running vSphere 5 Enterprise (with 32GB of vRAM entitlement per processor license) then you need 400GB / 32BG = 13 licenses.  As you notice, there is no mention of physical RAM in this calculation.  To recap, vSphere 5 licensing needs are determined by only 3 factors:

Number of VMs

Amount of vRAM per VM

What vSphere 5 edition you are running. The entitlements for the different editions are available here.

Our Technical Marketing team has developed a tool that can help you add the total amount of vRAM allocated in your VMs so that you can run this calculation.  There is also an accompanying video explaining how to use the tool.  In addition, we have noticed a few similar tools developed by the community.

How we got to vRAM

When we began the process of developing the new model, we set out to find a way to evolve vSphere’s licensing to lay the foundation for customers to adopt a more "cloud-like" IT cost model.  We were looking to develop a model that would be more congruent with the technology architecture of the virtual and cloud world, where resources are pooled for maximum utilization.  In short, we wanted a model based on consumption and value rather than physical components and capacity.

The design point of the licensing change was not to increase licensing costs, and we believe  90+% of our customers will not see a licensing cost increase.  Before we introduced the new vSphere 5 licensing model, which is based on pooled vRAM entitlement, we did a great deal of research, and carefully analyzed available customer data. Let me tell you what we found:

The average amount configured vRAM per VM is 3GB

The average number of VMs per physical processor is 5.7. I know this may be counter-intuitive to some customers who are pushing the envelope, but the detailed distribution of consolidation ratios is on the graph below.


So based on the above two metrics, even if you disregard the effect of vRAM pooling, the vRAM entitlements far exceed the common customer practice. In fact, some customers may see a decrease in their licensing costs: customers of vSphere Essentials, Essentials Plus, Standard, and Enterprise had 6-core per proc restrictions in the previous licensing model. In order to deploy vSphere on a new server with more than 6 cores per processor, these customers would have had to purchase additional vSphere licenses.


We are confident that as we move into the cloud computing era, our vSphere 5 vRAM licensing model will allow our customers to best take advantage of the benefits and flexibility of cloud computing by allowing the pooling of licenses for maximum utilization and value:

As Forrester’s James Staten writes in his blog: “This change ties licensing more to the use of the product and encourages greater VM consolidation as it counts VMs by size, rather than per physical server. This incents packing lots of VMs on a single system and even lets you share vRAM entitlements across physical systems to accommodate more seamless growth of your environment and management of the pool, a key operational change called out in our Virtualization Maturity Model. Basically, now you can entitle your virtual environment in total, based on its capacity and fill it up as much as you want. This is much more consistent with their service provider pricing model; and if your goal is to build a private cloud, isn’t that the point? All in all, this shows that VMware gets it and is taking an active role in helping educate its customers that virtualization and cloud operations are two different things and making these distinctions clear is critical to their and your success. Well done, VMware.”

And as the Taneja Group remarked: “We welcome this new approach, and believe it addresses the majority of licensing concerns that we’ve heard from VMware customers over the past couple of years.  First, it’s much simpler – users can now focus on how they actually use vSphere virtual resources on a given pool of physical servers, versus having to worry about how those underlying servers’ processor and memory configurations might grow.  And since baseline licensing is still tied to number of server cpu’s, the new licensing will not force changes to customers’ existing purchasing and budgeting processes.”

To wrap up, I would like to point to some of the advantages of the new model as articulated by some of our customers:  

The great thing about the new licensing model is that you don’t have to buy all your licensed capacity up front if you think you’re going to be running a large amount of vRAM eventually. You can license the minimum and then purchase licenses just when required to be in compliance.
--Michael at

VMware has now leveraged itself to provide a very measurable licensing cost per VM that Cloud providers can then accurately charge back to their customers.  In VMware’s eyes this goes for both internal private clouds and external public clouds.

I encourage you to download the tool and estimate you actual vRAM usage across your entire environment. Talk to your VMware or partner sales team to go through the numbers. For more information and materials, visit the vSphere 5 Upgrade center.

Rethink IT: VMware: Building the Foundation for the Cloud Era with the launch of vSphere 5 and the Cloud Infrastructure Suite

VMware Blogs

Today marks a major milestone for us here at VMware. Not only did we announce a new major release of our flagship virtualization and cloud platform, vSphere 5, but we also unveiled a comprehensive suite of cloud infrastructure technologies that are purpose-built to help customers transform their virtualized datacenters into cloud environments.


The Console: VMware Unveils vSphere 5 and the Cloud Infrastructure Suite

VMware Blogs

Today is a great day at VMware as we launch our cloud infrastructure suite, a coordinated advance in the collection of software required to build secure, efficient, and enterprise-ready clouds. Today’s announced releases include vSphere 5, vCenter Site Recovery Manager 5, vShield 5, vCloud Director 1.5, and the new vSphere Storage Appliance 1.0.  These are joined by vCenter Operations, which we launched in March of this year, to complete the offering.


Uptime: Look what's new with VMware vCenter Site Recovery Manager v5.0!

VMware Blogs

Hello all,

I have been working on SRM 5 for a long time.  So has a very large group of people.  We are all very happy that it is announced today and I cannot wait for everyone to have access to it!  Here today I want to show you some of the important new features so you can start thinking how they will help you.  And make no mistake: there is a lot of changes!


Uptime: vSphere 5.0 is released with new HA features!

VMware Blogs

Today VMware announced the release of VMware vSphere 5.0.  This is a huge release!  Some of the key features of this release include:

Convergence. vSphere 5.0 is the first vSphere release built exclusively on the vSphere ESXi 5.0 hypervisor architecture as the host platform.

VMware vSphere Auto Deploy. VMware vSphere Auto Deploy simplifies the task of managing ESXi installation and upgrade for hundreds of machines.


VMware vSphere Blog: vSphere 5.0 Storage Features Part 1 - VMFS-5

VMware Blogs

One of the primary objectives of Storage enhancements in 5.0 is to make the management of storage much simpler. One way to do this is to reduce the number of storage objects that a customer has to manager, i.e. enable our customers to use far fewer and much larger datastores. To that end, we are increasing the scalability of the VMFS-5 filesystem. These scalability features are discussed here. In future postings, I will discuss further features which aim to fulfil this vision of simplifying storage management.


VMware vSphere Blog: vSphere 5.0 Storage Features Part 2 - Storage vMotion

VMware Blogs

Storage vMotion allows the migration of running VMs from one datastore to another without incurring any downtime. It was first introduced as a mechanism to assist customers to move VMs from VMFS-2 to VMFS-3 (without incurring VM downtime) when moving from ESX 2.x to ESX 3.0.1. In fact, we didn't even call it Storage vMotion back then, but referred to it as something called Upgrade vMotion (?).


VMware vSphere Blog: vSphere 5.0 Storage Features Part 3 - VAAI

VMware Blogs

In a previous post, I mentioned that one of the primary objectives of Storage enhancements in 5.0 is to make the management of storage much simpler. In order to do this we are trying to encourage customers to use much larger and far fewer datastores.

One feature that assists in achieving this goal is Thin Provisioning. However, there were two factors with Thin Provisioned datastores which raised concerns for many customers.


ESXi Chronicles: What's New with ESXi in vSphere 5.0?

VMware Blogs

Following yesterday's big vSphere 5.0 announcement I'm sure many of us are suffering from a bit of information overload.  In order to help navigate through the many new features, and help acquaint everyone with 5.0, I thought it would be good here on the ESXi Chronicles to start our 5.0 journey by calling out a few of the more significant new features and capabilities related to the ESXi core platform.  These include:


Uptime: What's New in vSphere 5.0 Whitepapers

VMware Blogs

Since Roger Lund already mentioned on his blog, I figured now's as good as of time as any to mention these whitepapers we created.  These are a series of whitepapers made by the Technical Marketing staff to help you understand some of the new features in the 5.0 release.  There are several short papers, each on different topics so you can pick and choose what you want to read about.  I'd highly suggest giving them a read, and if you have any feedback, please do let us know.

VM HA – Laying a foundation for today and tomorrow

Virtual Geek Chad Sakac

With vSphere 5, VM HA gets a ground up re-write – which is, IMO long overdue.

I can remember the first time I was playing in a home lab with VMware Infrastructure – the VM HA configuration wouldn’t work, and it SUCKED to troubleshoot.   3 guesses on what my problem was… well, only 1 guess needed… DNS :-)   The “rule of 4” around DNS was super-important for the oh-so-super sensitive VM HA agents to play nicely.   And OH, the error messages and logging always was a source of frustration.


VMFS-5–what you need to know in a nutshell….

Virtual Geek Chad Sakac

It’s new, and it’s good :-)

VMFS-5 increases limits (without increasing extents) to 64TB.

It enables 2TB+ RDMs.

It uses a common allocation size of 1MB.

It increases the small block allocations available for total use.

It is a dependency for SCSI UNMAP

It uses the VAAI HW accelerated locking more extensively.


5 is the magic number

Yellow Bricks Duncan Epping

Yes, here it is… the moment we’ve all been waiting for… vSphere 5.0. Finally announced today, and on top of that also new releases of vCD (1.5), SRM (5.0), vShield (5.0) and of course a new product called the vSphere Storage Appliance. Over the last months I have been working hard on collateral for this launch and soon it should be available. For me personally vSphere 5.0 is most definitely the launch that had the most impact ever. Not only did I work on some of the material that will be released, I also prepared roughly 20 blog articles which will be released over the upcoming weeks and lets not forget the vSphere 5.0 Clustering Tech Deepdive that we’ve released today. Crazy times indeed, but that’s not the topic of this article. Lets talk about vSphere 5.0 for a bit and why I am so excited about this release in particular. I could do a copy of past of the releasenotes, which I am certain many will do, but where’s the fun in that? Instead I am going to list some of the changes in vSphere 5.0 and mention why I feel these are important. I won’t go into much detail yet as that will more than likely happen in one of the upcoming articles.


vShield App 5 Data Security = awesomesauce and free to try…

Virtual Geek Chad Sakac

Well, I’m sure I’m biased, but I think the new security capabilities are potentially one of the biggest parts of the vSphere 5 release wave.

Fundamentally, just like the explosion of data has turned out to be a blessing in disguise (with the emergence of Big Data Analytics) – the fact that virtualization “broke” security models is a similar blessing.

vSphere 5.0: Storage DRS introduction

Yellow Bricks 13/07/11 4:00 AM Duncan Epping Server 5.0 Storage storage drs vSphere

Storage DRS is a brand new feature of vSphere 5.0. It has been one of my focus areas for the last 6 months and probably one of the coolest features of vSphere 5.0. Storage DRS enables you to aggregate datastores in to a single object, called a datastore cluster. This new object is what you will be managing from now on. Storage DRS enables smart placement of virtual machines based on utilized diskspace, latency and LUN performance capabilities. In other words, when you create a new virtual machine you will select a Datastore Cluster instead of a Datastore and Storage DRS will place the virtual machine on one of the datastores in that datastore cluster. This is where the strength lies of Storage DRS, reducing operational effort associated with provisioning of virtual machines…


VMware’s Launch Event

Today was a big day for VMware. I’m going to provide some summary coverage of the products launched today, but only a quick recap; I’ll have more in-depth analysis and information on the products and their key features and improvements in future blog posts. No doubt there is going to be plenty of other coverage on the launch as well, and I’ll likely produce a special “Short Takes” episode with a summary of some of the related links, so look for that as well.


What's New in VMware vCenter Site Recovery Manager 5

NTPRO.NL - Eric Sloof (Eric Sloof)

vCenter Site Recovery Manager builds on the core properties of VMware vSphere that already provide basic protection of applications. Site Recovery Manager is a product that simplifies and automates disaster recovery. Site Recovery Manager helps organizations to directly address the challenges of disaster recovery that were mentioned earlier:  meeting RTO requirements, reducing cost, and reducing risk Site Recovery Manager is a separate product from VMware vSphere.


vSphere 5 What's New - High Availability (HA)

NTPRO.NL - Eric Sloof (Eric Sloof)

VMware HA clusters enable a collection of ESXi hosts to work together so that, as a group, they provide higher levels of availability for virtual machines than each ESXi host could provide individually. When you plan the creation and usage of a new VMware HA cluster, the options you select affect the way that cluster responds to failures of hosts or virtual machines.


vSphere 5 What's New - Profile Driven Storage

NTPRO.NL - Eric Sloof (Eric Sloof)

So what does Profile-Driven Storage try to achieve? Very simply - minimize the amount of time required to provision virtual machines. Provisioning virtual machines isn’t only just selecting a random datastore. You will need to know what the requirements are of the virtual machine and then select the appropriate volume to the best of your knowledge. Profile-Driven Storage tries to help with that by providing better insight into storage characteristics and allowing for custom-tags and linking virtual machines to profiles. vSphere Storage APIs for Storage Awareness is a new set of APIs which will enable vCenter to see the capabilities of the storage array LUNs/datastores, making it much easier to select the appropriate disk for virtual machine placement.


vSphere 5 What's New - Image Builder and Auto Deploy

NTPRO.NL - Eric Sloof (Eric Sloof)

Auto Deploy is a new method for provisioning ESXi hosts in vSphere 5.1.  At a high level the ESXi host boots over the network (using PXE/gPXE), contacts the Auto Deploy Server which loads ESXi into the hosts memory.  After loading the ESXi image the Auto Deploy Server coordinates with vCenter Server to configure the host (using Host Profiles and Answer Files (answer files are new in 5.0).  Auto Deploy eliminates the need for a dedicated boot device, enables rapid deployment for many hosts, and also simplifies ESXi host management by eliminating the need to maintain a separate “boot image” for each host.


What's New in VMware vShield 5

NTPRO.NL - Eric Sloof (Eric Sloof)

For vSphere-based environments, vShield solutions provide capabilities to secure the edge of the vDC, protect virtual applications from network-based threats, and streamline antivirus protection for VMware View deployments by offloading AV processing to dedicated security VMs. These new product offerings can start securing infrastructure almost immediately since all the underlying compute resources are already present in the vsphere environment.

What's New in VMware vCloud Director 1.5

NTPRO.NL - Eric Sloof (Eric Sloof)

In vCloud Director 1.0, VM provisioning operations resulted in the creation of full clones, delivered to users within minutes through a simple web portal. With the enablement of linked clones in vCloud Director 1.5, users no longer have to wait for a full copy each time they deploy a vApp. vCloud Director “links” clones together so that common elements are stored only once. This improves agility in the cloud by reducing provisioning time, from minutes down to seconds, and reducing the cost of storage by up to 10x.


vSphere 5 What's New - Storage DRS

NTPRO.NL - Eric Sloof (Eric Sloof)

This feature delivers the DRS benefits of resource aggregation, automated initial placement, and bottleneck avoidance to storage. You can group and manage similar datastores as a single load-balanced storage resource called a datastore cluster. Storage DRS makes VMDK placement and migration recommendations to avoid I/O and space utilization bottlenecks on the datastores in the cluster. Storage DRS takes care of the initial placement of virtual machines and VMDK files. This placement is based on Space and I/O capacity. Storage DRS will select the best datastore to place this virtual machine or virtual disk in the selected Datastore Cluster. When Storage DRS is set to fully automatic, it will do automated load balancing actions. Of course this can be configured as manual as well and that is actually the default today. Load balancing again is based on space and I/O capacity. If and when required Storage DRS will make recommendations based space and I/O capacity. It will however only do this when a specific threshold is reached.


vSphere 5.0: What has changed for VMFS?

Yellow Bricks Duncan Epping

A lot has changed with vSphere 5.0 and so has one of the most under-appreciated “features”…. VMFS. VMFS has been substantially changed and I wanted to list some of the major changes and express my appreciation for the great work the VMFS team has done!


vSphere 5.0: Profile-Driven Storage, what is it good for?

Yellow Bricks Duncan Epping

By now most of you heard about this new feature called Profile-Driven Storage that will be introduced with vSphere 5.0, but what is it good for? Some of you, depending on the size of the environment, currently have a nice long operational procedure to deploy virtual machines. The procedure usually contains gathering information about the requirements of the virtual machine’s disks, finding the right datastore to meet these requirements, deploy the virtual machine and occasionally check if the virtual machine’s disks are still placed correctly. This is what Profile-Driven Storage aims to solve.

vSphere 5.0 Datastore Clusters & VDI Andre Leibovici

I have been fortunate enough to be part of the vSphere 5 Beta program. vSphere 5 really raise the bar and implement a number of new features; mostly around automated management. I’m sure there will be many blog posts listing those new features, so I decided to show some screenshots of those features.


vSphere 5 What's New - Storage Appliance (VSA)

NTPRO.NL - Eric Sloof (Eric Sloof)

In vSphere 5.0, VMware has released a new storage appliance called VSA. VSA is an acronym for “vSphere Storage Appliance”. This appliance is aimed at our SMB (Small-Medium Business) customers who may not be in a position to purchase a SAN or NAS array for their virtual infrastructure, and therefore do not have shared storage. Without access to a SAN or NAS array, SMB customers are unable to implement many of vSphere’s core technologies, such as vSphere HA & vMotion. Customers who decide to deploy a VSA can now benefit from many additional vSphere features without having to purchase a SAN or NAS device to provide them with shared storage.


vSphere 5 – vCenter as a linux VM

ESX Virtualization Vladan SEGET

VMware vSphere 5 brings new possibility to install and configure vCenter in a Linux VM.

The solution of having vCenter deployed through a simple OVF package without paying an additional license to Microsoft is tempting and encouraging. Especially for smaller customers, which aren’t on the Microsoft OVS package.  Also being able to protect this VM throught a HA (High availability) is a considered as a very good practice, since any failures of the underlying hardware are transparent for the end user.

The new vSphere 5  introduced by VMware has the possibility to have vCenter managed and installed in a Linux VM. The deployment process is apparently very easy since the product comes as a prepackaged and pre-instaled in an OVF format.


vSphere 5.0: Storage vMotion and the Mirror Driver

New Book - Professional vSphere 5: Implementation and Management

NTPRO.NL - Eric Sloof

This paperback written by John Hales, Brian Eiler and Steve Jones has not been released yet. You may pre-order it now and it will be delivered to you when it has been released. VMware vSphere, is VMware's first cloud operating system, able to manage large pools of virtualized computing infrastructure, including software and hardware. Building on the power of VMware Infrastructure, VMware vSphere dramatically reduces capital and operating costs, and increases control over IT infrastructures while preserving the flexibility to choose any OS, application and hardware. This book provides vSphere administrators with essential guidance in implementing and managing VMware's vSphere product suite. This guidance has been battle tested in virtual environments big and small. It also provides actionable advice for the day to day operational maintenance and common pitfalls to avoid for first time vSphere administrators. Best of all, the companion DVD contains an introductory version of Train Signal's vSphere training DVD that provides additional hours of vSphere training.

Hot of the press: vSphere 5.0 Clustering Technical Deepdive

Yellow Bricks Duncan Epping

After months of hard work the moment is finally there, the release of our new book: vSphere 5.0 Clustering Technical Deepdive! When we started working, or better said, planning an update of the book we never realized the amount of work required. Be aware that this is not a minor update. This book covers HA (full rewrite as HA has been rewritten for 5.0), DRS (mostly rewritten to focus on resource management) and Storage DRS (new!). Besides these three major pillars we also decided to add what we call supporting deepdives. The supporting deepdives added are: vMotion, Storage vMotion, Storage I/O Control and EVC. This resulted in roughly 50% more content (totaling 348 pages) than the previous book, also worth noting that every single diagram has been recreated and are they cool or what?


vSphere 5 for the SMB

Yellow Bricks Duncan Epping

I am live at the Launch event in San Francisco with many other bloggers, journalists and analysts. It is the 12th of July, almost 09:00 PDT and Paul Maritz is about come up on stage to talk about the Cloud Infrastructure launch. This article will be update live during the event as we go.


VMware vSphere can virtualize itself + 64-bit nested guests

VCritical Eric Gray

Running VMware ESXi inside a virtual machine is a great way to experiment with different configurations and features without building out a whole lab full of hardware and storage. Virtualization enthusiasts everywhere have benefited from the ability to run ESXi on ESXi, first introduced with the vSphere 4 release.

VMware vSphere 5 makes it easier than ever to virtualize hypervisor hosts. With new capabilities to run nested 64-bit guests and take snapshots of virtual ESXi VMs, the sky is the limit for your cloud infrastructure development lab.


BRKCOM-3002: Network Redundancy and Load Balancing Designs for UCS Blade Servers

This is BRKCOM-3002, Network Redundancy and Load Balancing Designs for UCS Blade Servers, presented by none other than M. Sean McGee (available as @mseanmcgee on Twitter; I highly recommend you follow him on Twitter if you are interested in UCS). I was really looking forward to this presentation, as I’ve spoken with Sean before and I know that he is a super-sharp UCS guru. Sean also blogs here.


Separate VMware vSphere Cluster For Management ?

vFAIL.NET Sean Crookston

One design decision I have heard more and more about this past year is the use of a vSphere Management Cluster, i.e. a separate cluster used entirely for management functionality such as vCenter, AD, DNS, etc..

Why create a separate Management Cluster? Perhaps there is a requirement to have management separated from the hosts physically. Perhaps you want to reuse your existing hardware and not purchase so much new hardware, so you are looking to create another smaller cluster.



My first vSPhere 5 “Monster VM” Andre Leibovici news virtualization vSphere5

Amongst all the new features introduced with vSphere 5, VMware increased the virtual hardware limits for virtual machines. What has so far been referred as “Monster VM” or “Super VM” is VMware’s ultimate move to help organizations to virtualize business-critical applications.
