VMware TAM Newsletter 3.01

From the editors Virtual Desk

 

Hi Everyone, well it seems as though apart from a few teething problems last week’s newsletter was received by all in good condition using the new system. I am very pleased with the result and intend to continue to refine the newsletter to better fit the needs of my customers. There were a few mentions on the size of the font last week so I have decided to make a change to try and ensure increased readability of the newsletter. Please feel free to send any other suggestions to make the newsletter more useful for you.

 

Next week I will be in the US for our yearly VMware kick off event. This is always something that I really look forward to and I am especially excited this year with all of the new products that we have introduced in the past year to see what we will be focusing on for the next year. The industry really is moving forward at a rapid rate and it does seem that many of our competitors are resorting to some strange tactics to catch up by using signage to try and create some FUD. But our wonderful customers know just how awesome our technology is and that we will continue to deliver on this promise which is what makes me especially proud to be a VMware employee.

 

This week’s newsletter is not as long as usual but I hope that you enjoy the newsletter, and find the format easier to digest.

 

Thanks you for reading this far, and please feel free to contact me anytime.

 

Best Wishes

How and where to change default ports for communication with ESX(i) hosts if needed

ESX Virtualization 22/01/11 2:49 AM Vladan SEGET Server Virtualization change default ports to connect to ESX or ESXi server Changing ports of ESX VMware ESXi changing ports

 

The title of the post says it all. If for whichever reason you need to change the default connection port for communication with ESX or ESXi i host, you might want to know where to go and how to modify it. And also which services (daemons) to restart.

Fist of all you must have an access to the console. For the ESXi server you’ll need to use vMA – vSphere Management Assistant, because the use of those vifs command requires the remote CLI application to be installed on the Workstation where the CLI is installed. You can download the vSphere Management Assistant (vMA) here.

How to install and use the vMA virtual appliance is explained in excellent new training from Trainsignal - vSphere Troubleshooting Training - created by David Davis.  I’m studying this course and I just few days ago I passed the section with the video explaining about how to configure vMA to connect to ESX(i) servers and how to use vMA.

Here is the how to for the change of the default ports on the ESX host:

 

Cores and more Cores… We don’t need them!

myvirtualcloud.net 12/01/11 8:51 PM Andre Leibovici vdi virtualization intel Nehalem VDI

 

 

In September 2010 during the IDF conference in San Francisco Intel unveiled their next-generation server Xeon CPU, which has been dubbed Westmere-EX. The numbers are  impressive, 10-core / 20 Thread Processor with ability to address 2TB of triple-channel memory, which is two times the addressable memory of the previous generation.

In May Intel announced a new 32-core server chip based on a new high-performance computing server architecture that mixes general x86 cores with specialized cores for faster processing of highly parallel scientific and commercial applications. The chip will be available in the second half of 2010.

“Knights Ferry includes 32 main Xeon chip cores in the server CPU socket, with corresponding 512-bit vector processing units in the PCI-Express slot. The chip runs four threads per core and includes 8MB of shared cache, and up to 2GB of fast GDDR5 memory.”

Fantastic pieces of technology for large number of different workloads, especially databases which will be able to run solely from memory as opposed to a non-volatile storage device. However, waste of money and deprecated high availability for VDI solutions.

My customers often ask me for my recommendations, and at the same time tell me that they had been thinking about buying Nehalem processors with four, six, or even eight cores. My answer invariable is a rhetoric question – Why?

PCoIP: Unleash the Throughput

myvirtualcloud.net 20/01/11 9:37 PM Andre Leibovici tips vdi virtualization PCoIP VDI view4.5 Vmware

 

 

PCoIP is a dynamic protocol and contains some very advanced mathematical algorithms to detect the ideal bandwidth, throughput, image quality and codecs to be utilised to stream contents to endpoints. These algorithms utilise arguments such as latency and variance to create what is called ‘rto’ metric. The higher the ‘rto’ the worse is the user experience. When ‘rto’ is close to 100 that’s when the link is in good conditions for a great user experience.

An alternative way for Changing/Resetting an ESXi 4.1 root password

NTPRO.NL - Eric Sloof 20/01/11 8:55 PM nospam@example.com (Eric Sloof) vSphere

This article is written by Ernst Cozijnsen.

A few days back after applying some patches via "Update Manager" we came to notice that our ESXi 4.1 host bacame unresponsive after a reboot. Loggin into the command prompt via ILO was unsuccessful too because the rootpassword was not working anymore. That just sucks!.... but nothing to get all emotional about since is just linux  (well a sort of...)

 

It is all a question about which path to take.

PlanetVM 21/01/11 6:33 PM Tom Howarth Backup General Storage Tips Windows vSphere

Planning storage is a simple thing,  you go to your Storage Admin’s and say, I need x amount of LUNs of this size please for my ESX servers and they NO, we only do xGB size LUN’s, or they breath thought their teeth like a motor mechanic or plumber and say, Storage doesn’t grow on trees you know, we don’t have much left, are you sure you really need all that space, etc.

The Future of SRM…

This article concerns the future of SRM. It’s a bit of an exclusive, as I got special clearance from VMware to put it together. Of course, I’m very close to the SRM folks, and VMware generally – so it wasn’t that hard. It’s worth saying that none of this stuff is commitment from VMware, and there are no time frames in the article. But it will give you an idea of where things are heading.

VCAP-DCA/VCAP-DCD Blueprints Updated

vFAIL.NET 10/01/11 11:00 PM Sean Crookston VCAP-DCA VCAP-DCD VMware certification

 

 

A few days ago it looks like both the VCAP-DCA and VCAP-DCD blueprints were updated to reflect new information.

VCAP-DCA

Being fairly familiar with the last couple versions of the blueprint I took a look at the new version (1.6) and see no real differences. I’m sure there is something but I could not find it so please comment if you see any of the differences.

VCAP-DCD

It is now confirmed via the blueprint that the exam is 113 questions. These questions are a mixture of multiple-choice, drag-and-drop, and design items using an in-exam design tool. Like the VCAP-DCA update I don’t see any real differences here either, although I am less familiar with this blueprint at this time.

We aren’t shy at this launch – and didn’t do it in a small way (watch the short video to get the highlights, and dive into the sub posts to get all the details – technical, videos, demos and more).   As the leader in shared storage, we wanted to dial this up to 12 :-)

 

VMware Support Insider: Troubleshooting VMware

VMware Blogs 13/01/11 12:34 AM

 

Today we have an interesting take today from one of our Trainers, Linus Bourque. Linus once worked on the front lines in Support, but now trains customers in troubleshooting and our products as well (more bio info at the bottom of this post).

One of my favorite IRC quotes comes from bash.org-

<erno> hm. I've lost a machine.. literally _lost_. it responds to ping, it works completely, I just can't figure out where in my apartment it is.

Although I can admit to never having to run into this issue when troubleshooting, it does highlight something needed by all within the I.T. community, and that is the ability to troubleshoot issues; is of the most powerful skills that anyone needs. While we can learn pretty much any product, how to deal with it when things go wrong is another skill set entirely.

Today we have a guest post from Bryan Hornstein, who works in our Broomfield, CO. office. Bryan is a Technical Support Engineer currently in a rotational role to create content for the Knowledge Base. Another in our Resolution Paths series, here are two Resolution Path Knowledgebase articles that will help you sort out some common issues getting VMware Update Manager installed.

VMware Update Manager is a great product, and it allows us to do so many things that would normally take hours to do manually. With a simple point and click Update Manager can do several tasks at once, freeing us System Administrators to do other tasks that our companies need.

Dynamic Cluster Pooling

2vcps and a Truck 21/12/10 6:26 AM Jon Owings capacity performance powershell

Dynamic Cluster Pooling is an idea that Kevin Miller ( @captainstorage) and I came up with one day while we were just rapping out some ideas on the whiteboard. It is an incomplete idea, but may have the beginnings of something useful. The idea is that clusters can be dynamically sized depending on expected workload. Today a VMware Cluster is sized based on capacity estimates from something like VMware Capacity Planner. The problem is this method requires you apply a workload profile across all time periods or situations. What if only a couple days of the month require the full capacity of a cluster. Could those resources be used elsewhere the rest of the month?

 

A Quick Review of VPLEX Storage Objects

Now that I’ve managed to get my VPLEX clusters up and running, I’m ready to start providing some posts on VPLEX and how it’s configured and used. To get things started, I want to first provide an overview of VPLEX storage objects and how they relate to each other.

Some EMC Product Updates

There have been a few important EMC product updates over the last few days that I thought I might highlight here real quick:

Replication Manager has been bumped up to version 5.3.1 (also referred to as 5.3 SP1), which adds several new features. One of the more notable features is the ability to do file-level restores from both VMFS and NFS datastores. Other new features include the ability to create SnapView snaps or clones from RecoverPoint targets and expanded host and application support.

In my previous post on EMC VPLEX, I provided a review of the VPLEX storage objects. In that post, I discussed the difference between a storage volume, an extent, a device, and a virtual volume. If you are unclear on the distinctions between those terms, I suggest you go back and read that post again before proceeding.

The following diagram illustrates these various storage objects again:

The security has been tightened in vSphere 4.1, so that’s why by default if you install vSphere 4.1 or if you upgrade your vSphere 4.0 installation, you can’t copy paste between the VI client and the VMs running in your vSphere environment.  You can read more about why it was changed in vSphere 4.1 in ESX 4.1 configuration guide (page 213). To be able to copy and paste between the guest operating system and the remote console, you must enable the Copy and Paste option.

 

How to activate the PAC when you purchase VMware product through a partner

ESX Virtualization 22/12/10 2:00 AM Vladan SEGET Videos License VMware activation process Partner Activation Code VMware Explained Vmware PAC

Partner Activation Code – (PAC) activation procedure.

PAC stays for Partner Activation Code. When customer buys a VMware product through an OEM partner, he’ll need to activate the PAC first to be able to get the License Activation Code (LAC)/Serial number. If the customer has been registered with VMware in the past, he’ll needs to sign in. Otherwise, he’ll have to register first.

The PAC is for single use. After its registration, the PAC is not needed anymore, since you’ll be able to get a serial at the end of the registration process.  After the PAC is registered, you’ll have to look for an email with the product serial # or LAC.   Also during the registration process you have the possibility to add the e-mail of the person who is responsible to administer the license.

 

How to make sure that the correct ISO image is loaded when Installing VMware Tools

Checking if the ISO is loaded.

Sometimes you have a Windows VM with autostart for a CD drive disabled. In this case the VMware tools installation does not start automatically.  You can run into 2 different situations.

Case 1: The Vmware tools installer does not start:

01 - Click Start > Run from the inside guest operating system.
02 - Type D:\setup.exe where D: is the first CD-ROM drive configured for your virtual machine.
03 – Click OK to start installing VMware Tools.
.
Case 2: The setup fails to start as the ISO was not mounted to the CD-ROM drive:
01 - Right-click the virtual machine you want to install VMware Tools on, in your inventory. Choose Edit Settings.
02 – Select CD/DVD Drive.
03 – Make sure that the the connected check box is selected.
04 – Choose Datastore ISO file > Browse > vmimages > tools-isoimages > windows.iso
05 – Type D:\setup.exe again to start the installation

 

Suspend Power Policy in VMware View. Should you use it?

myvirtualcloud.net 14/12/10 6:39 PM Andre Leibovici tips vdi virtualization VDI View view4.5

One of my readers posted a comment on my VDI Calculator page mentioning that he would not see the VM storage consumption increasing when Suspend VM option was select at “Desktop State when Not in use”.  Suresh Thoppay thanks for the comment!

According to Suresh, “ESX suspend file, which has a .vmss extension, is created if you set the desktop pool policy to suspend on logoff. The size of this file is equal to the size of guest RAM.”

His explanation is spot on! So I diligently reviewed my formulas and not satisfied with the results I performed some tests in my lab. It turns out that the original formula was working, however it was taking into consideration the difference between the total number of VMs and concurrent VMs.

 

 

Get hold of VDI IOPs, Read/Write Ratios and Storage Tiering

myvirtualcloud.net 29/12/10 11:34 AM Andre Leibovici storage tips vdi virtualization VDI view4.5

Getting the right storage requirements for VDI can be tricky in most situations. The reason for that is the lack of information about the workload that will be running in each one of the virtual desktops. It is possible to use some pre-trended numbers as baseline, however despite this would be an indication of what the workload would likely be, it could be a point out of the curve in many cases. In the nirvana scenario the customer would have been already running a pilot and that data could be collected and trended.

Cloudy Thoughts

RTFM Education 15/12/10 1:51 AM Mike Laverick Cloud

I’ve been thinking about the cloud a lot in the last year – and speaking to both the sellers of cloudy software, as well as customers thinking of going down the cloud route. For sometime I’ve though the cloud might be more attractive to SMB customers – not so much the private cloud obviously, but the public cloud. After all if I’m small business or start-up why would want all the grief and hassle of managing my own physical or virtual infrastructure when I can have VMs outsourced to a third party. Well, any more of this theme on over on TechTarget’s site where I’ve written an article about this subject..

 

ISV Support – The biggest barrier to virtualization

RTFM Education 15/12/10 2:03 AM Mike Laverick Other

One of the things that is often discussed is what the biggest barriers are to virtualization – frequently this discussions focus on performance, internal politics and cost of licensing. But have you ever thought that one of the biggest barriers to virtualization – is the very software vendors? Quite often their support/EULA statements are rubbish, and they deliberately frame the licensing to make it cost prohibitive to virtualize. Often the motivation to do this – is to stick to one of their competitors. So much for the helping the customer over come their “challenges” huh. I wax lyrical about this – using Oracle as an example – over on TechTarget.

Hyper-V is nearing the end of a long march to memory overcommit when they finally release Dynamic Memory early next year in Service Pack 1, but please do not call it “overcommit” when Microsoft Virtualization is around — it really riles them up.  Just think of this new Dynamic Memory feature as memory thin-provisioning; each VM has the potential to utilize more physical memory as demand grows, just as long as another VM doesn’t request it first.

Fun fact: The billboard on the opposite side is running an Apple iTunes ad.

“VIRTUALIZATION ALONE DOES NOT A CLOUD SOLUTION MAKE.”

Catchy, yet sophisticated and original.

Your witty comeback could win you a cool vSphere book!

The possibilities are endless.  Keep it clean.

For instance, you might reply:  “Yeah, I’d say the exact same thing if my virtualization was Hyper-V.”

 

Home Lab Setup : VLANs and Routing

vFAIL.NET 20/12/10 10:00 PM Sean Crookston VMware dd-wrt. vlan routing lab

 

A few months back I began thinking about doing a few things to my home lab setup to give it a little extra in terms of the capabilities it had. One thing near the top of my list was beefing up the network side of things a little bit.

Originally I had just the two hosts hooked up to a couple of 8 port gigabit switches. For the most part this was perfectly fine as I had full gigabit connectivity along with Jumbo frames. What was lacking though was manageability of the switch and VLANs.

 

vCenter 4.1 Upgrade – Error 1719 The Windows Installer Service Could Not Be Accessed

vFAIL.NET 3/01/11 11:00 PM Sean Crookston VMware vcenter 4.1 upgrade vsphere

 

Upon attempting to upgrade a vCenter server to 4.1 I was presented with and error like the below.

Error 1719 – The Windows Installer Service could not be accessed

My first thoughts were around how I would have to build a new vCenter server because the Windows Installer Service was completely hosed. After some initial troubleshooting I was still not able to get the install working, however a quick search for vcenter and error 1719 presented me with a solution that resolved a similar issue with VMware Tools installations on Windows 2008 x64 operating systems.

The issue was simply related to a registry key that when set only allows the Windows Installer service to handle 32 bit installers. Why it was set like this on the machine or that you’d event want this ‘capability’ I have no idea.

 

The solution as posted in the kb article here for VMware Tools is

 

VCAP-DCA/VCAP-DCD Blueprints Updated

vFAIL.NET 10/01/11 11:00 PM Sean Crookston VCAP-DCA VCAP-DCD VMware certification

 

 

A few days ago it looks like both the VCAP-DCA and VCAP-DCD blueprints were updated to reflect new information.

VCAP-DCA

Being fairly familiar with the last couple versions of the blueprint I took a look at the new version (1.6) and see no real differences. I’m sure there is something but I could not find it so please comment if you see any of the differences.

VCAP-DCD

It is now confirmed via the blueprint that the exam is 113 questions. These questions are a mixture of multiple-choice, drag-and-drop, and design items using an in-exam design tool. Like the VCAP-DCA update I don’t see any real differences here either, although I am less familiar with this blueprint at this time.

 

Understanding vSphere Disaster Recovery/Avoidance options

Virtual Geek 21/12/10 7:40 AM Chad Sakac

Wrapping up all the blog posts in one place, and including a webcast and powerpoint on the topic.

Phew – that was a lot of work, right in the middle of the 2011 planning cycle :-)

The blog series is: “Understanding vSphere Disaster Avoidance/Recovery” – discussing a broad topic: state of the union of vSphere non-disruptive disaster avoidance and disaster recovery solutions, and how they interact (because it ain’t easy to do both together when you dive in deep).

Read Post I: Discusses the 4 key solution categories in this space.  Read it here.

Read Post II: Discusses one of solution (stretched vSphere cluster and VPLEX) and gory failure scenarios in detail.  Read it here.

Read Post III: Discusses what’s going on in this space (and where EMC R&D efforts are centered).  Read it here.

 

Uptime: Helping you to install SRM!

VMware Blogs 17/12/10 8:23 AM

Hello everyone,

I have some resources to share with you to make it a little easier to install SRM, but I wanted to make sure first that everyone understands that making SRM work is just a small part of a DR project, and while sometimes a little complicated, it is generally the easist part of the DR project.  That is why I often recommand people involve outsiders in the form of professional services in a DR project as their experience can often help greatly to make a project successful.  Not just with SRM, but also in the rest of the project.

 

VROOM!: Performance Scaling of an Entry-Level Cluster

VMware Blogs 18/12/10 6:18 AM

Performance benchmarking is often conducted on top-of-the-line hardware, including hosts that typically have a large number of cores, maximum memory, and the fastest disks available. Hardware of this caliber is not always accessible to small or medium-sized businesses with modest IT budgets. As part of our ongoing investigation of different ways to benchmark the cloud using the newly released VMmark 2.0, we set out to determine whether a cluster of less powerful hosts could be a viable alternative for these businesses. We used VMmark 2.0 to see how a four-host cluster with a modest hardware configuration would scale under increasing load.

VMware vCloud Blog: Cloud Architecture Patterns: Service VM

VMware Blogs 21/12/10 11:14 AM

By Steve Jin, VMware R&D

Intent

Provide an easy way to provision new infrastructure and application services for a computing cloud

Category

Behavioral

Problem

To run a large-scale computing infrastructure, you will need many different types of services, including compute, storage, and networking, among others. After virtualization has successfully detached compute from the physical hardware, it’s very easy to provision and scale compute. But compute requires storage and networking which are lagging behind. To maximize the benefits of virtualization and cloud computing, it’s natural to push the storage and networking in the same direction.

Looking beyond the infrastructure to consider applications, we need various types of services such as database, directory, messaging, and more. I’ve covered the App VM pattern that allows using IaaS for PaaS in a previous blog. While you can pack some of these services into an application VM, the problem is that it scales well but does not follow the aspectual centralization pattern.

 

VMware Support Insider: Changes to Snapshot Consolidation

VMware Blogs 24/12/10 6:25 AM

Another guest post today from Simon Todd, who is a Tech Support Engineer in our Cork, Ireland office who specializes in Storage issues.

Anyone using snapshots has probably run into this issue once, twice or many times:

When trying to perform an online consolidation there is not enough space on the Datastore to perform the consolidation.

This is mainly due to the way snapshots are consolidated. To illustrate this, let’s look at an example where we have a virtual machine residing on a 600Gb VMFS Datastore that has a 500Gb base disk, and that virtual machine has 8 levels of snapshots of the following sizes:

 

VMware ThinApp Blog: Locally installed applications and integration with virtualized Internet Explorer

VMware Blogs 4/01/11 12:14 AM

Perhaps one of the hottest use cases for ThinApp currently is virtualizing Internet Explorer 6. I have found a somewhat generic fix to make integration between virtualized IE6 and locally installed applications. The fix is discussed in a previous blog post (http://blogs.vmware.com/thinapp/2010/03/how-to-resolve-send-to-email-issues-from-applications-like-reflection.html) but might not be that obvious.

VROOM!: Experimenting with Cluster Scale-Out Utilizing VMmark 2

VMware Blogs 8/01/11 1:51 AM

The first article in our VMmark 2 series gave an in-depth introduction to the benchmark while also presenting results on the scaling performance of a cluster based on a matched pair of systems.  The goal of this article is to continue to characterize larger and more diverse cloud configurations by testing scale-out performance of an expanding vSphere cluster.  This blog explores an enterprise-class cluster’s performance as more servers are added and subsequently the amount of work being requested is increased. Determining the impact of adding hosts to a cluster is important because it enables the measurement of the total work being done as cluster capacity and workload demand increases within a controlled environment.  It also assists in identifying the efficiency with which a vSphere managed cluster can utilize an increasing number of hosts.

Oracle RAC Performance on vSphere 4.1

VROOM! 17/12/10 6:21 AM Todd Muirhead

 

 

Oracle Real Application Clusters (RAC) is used to run critical databases with stringent performance requirements. A series of tests recently were run in the VMware performance lab to determine how an Oracle RAC database performs when running on vSphere. The test results showed that the application performed within 11 to 13 percent of physical when running in a virtualized environment.

 

 

HA Cluster Improvements

vSphere PowerCLI Blog 16/12/10 7:48 PM Vitali Baruh

PowerCLI 4.1.1 introduces three new improvements for HA clusters:

Ability to edit advanced HA cluster settings

Cmdlet that retrieves the primary nodes of HA cluster

Set of new properties that contain runtime HA information

 

The first of the new features is the ability to edit the advanced settings of HA clusters. There are four new cmdlets that allow you to customize HA settings - Get-AdvancedSetting, New-AdvancedSetting, Set-AdvancedSetting, and Remove-AdvancedSetting.

 

Shares set on Resource Pools

Yellow Bricks 15/12/10 12:32 AM Duncan Epping Server Various 4.0 4.1 drs resource pools VMware vSphere

During our session at the Dutch VMUG Frank was explaining Resource Pools and the impact of limits and reservations. As I had the feeling not everyone in the room was using resource pools I asked the following questions:

 

vCenter and Memory metrics

Yellow Bricks 21/12/10 12:43 AM Duncan Epping Server Various 4.1 vcenter vSphere

I received a question last week from a former colleague around some of the memory details in vCenter. There are a couple of places where memory details are shown on a “VM level” within the vCenter client. The first tab that we will discuss is the Summary tab. It shows “General” and “Resources”. It appears that there is a lot of confusion around this topic and that probably comes from the fact that some of the Performance Metrics are named similarly but don’t always refer to the same.

 

How cool is TPS?

Yellow Bricks 11/01/11 3:39 AM Duncan Epping Server 4.1 esxtop memory performance tps troubleshooting VMware vSphere zero

Frank and I have discussed this topic multiple times and it was briefly mentioned in Frank’s excellent series about over-sizing virtual machines; Zero Pages, TPS and the impact of a boot-storm. Pre-vSphere 4.1 we have seen it all happen, a host fails and multiple VMs need to be restarted. Temporary contention exists as it could take up to 60 minutes before TPS completes. Or of course when the memory pressure thresholds are reached the VMkernel requests TPS to scan memory and collapse pages if and where possible. However, this is usually already too late resulting in ballooning or compressing (if your lucky) and ultimately swapping. If it is an HA initiated “boot-storm” or for instance you VDI users all powering up those desktops at the same time, the impact is the same.
