Hi everyone, last week’s newsletter was really long and I hope that you enjoyed all of the new sections such as the Security section. This week I have no additional security news however I do have some news on a few of our other technologies aggregated via their newsletter. For those that receive these as well I apologise for the double up.

This week we held our first Lunch and Learn session in Brisbane. The session was very well attended and the feedback was very positive. Next week’s session is on VMware Capacity IQ. Details are at the end of this newsletter as they will be for each lunch and learn session. If you want to attend please don’t forget to register as space is always limited.


I was reminded by a colleague the other day that in January I passed my 2 year mark as a VMware employee. I had completely forgotten about this but it made me think how much has changed even in my short time at this amazing company. It also marks 2 years of newsletters. I have delivered around 100 of them since I joined VMware. I love doing the newsletter and even if there was 1 person who read the newsletter I would continue with the service. I hope that you get something out of the newsletter and of course please keep in contact if you have any suggestions or anything you wish to share with me or the TAM community.

Take care until next time

Video - VMware MVP (Mobile Virtualization Platform)

VMware MVP allows users to carry a single device for both personal and corporate usage. Employees want to use their personal smartphone for work and are pushing IT to support those devices. This trend—sometimes called “Consumerization of IT”—challenges IT requirements for security, compliance and ease of management. VMware MVP enables enterprises to embrace this trend, by allowing IT to safely support employee owned devices. With VMware MVP, enterprises can get the security and ease of management they require, while reducing CAPEX.



Performance Troubleshooting for vSphere 4.1

Chethan Kumar of VMware dropped me an e-mail last night (as he did to several other bloggers, I think) asking me to help raise awareness of the new release of the performance troubleshooting white paper for VMware vSphere 4.1. You can download the white paper here.

Some of the new sections added to this document, based on Chethan’s post to the VMware Communities site, include:

Troubleshooting performance problems in resource pools (both on standalone hosts and DRS clusters)

Additional troubleshooting steps around memory pressure (including hosts with compressed or swapped memory)

High CPU ready time in hosts that are not CPU saturated

Environments using snapshots


vSphere Integration With EMC Unisphere

If you manage EMC unified storage running at least FLARE 30 and DART 6, or if you’re using a recent version of the UBER VSA, or if you’re one of the fortunate few who have had your hands on the new VNX series, then chances are you’re familiar with or you’ve at least experiencedUnisphere, which is EMC’s single pane of glass approach to managing its multi protocol arrays.  For what is essentially a 1.0 product, I think EMC did a great job with Unisphere.  It’s modern.  It’s fast.  It has a cool sleek design and flows well.  They may have cut a few corners where it made sense (one can still see a few old pieces of Navisphere code here and there) but what counts for me the most at the end of the day is the functionality and efficiency gained by a consolidation of tools.


Updating ESXi 4.1 to Update 1 brings an error vim.fault.noHost

When I was trying to update the latest Update 1 I got an error on one host.

The error message says Install error on host: error details: vim.fault.noHost. It was quite strange since both other hosts I was updating went smooth without any errors. I was trying to apply those patches via CLI without success either. Then I did a quick research on Google and I found a reply on a VMware communities here.

Then I took a quick look at my host, and there were 2 orphaned VMs which were pointing to disconnected datastore, which wasn’t used anymore. I did unregister those 2 VMs and try to patch the host again. The problem was solved and the host patched successfully.

A quote from the solution:

If you have any invalid, inaccessible or orphaned VMs (like me) in the inventory, you should unregister those virtual machines and try again with update in Update Manager.

New Troubleshooting Guide - Performance Troubleshooting for VMware vSphere 4.1

Performance problems can arise in any computing environment. Complex application behaviors, changing demands, and shared infrastructure can lead to problems arising in previously stable environments. Troubleshooting performance problems requires an understanding of the interactions between the software and hardware components of a computing environment. Moving to a virtualized computing environment adds new software layers and new types of interactions that must be considered when troubleshooting performance problems. 

New Article – Adding capacity to the Reserved LUN Pool

Another simple one that I thought was worth documenting for the cosmetic changes in Unisphere. You can find it here. Check out the rest of my equally exciting guides here.


EMC CLARiiON Basics – Service LAN Connectivity

Brian at Going Virtual had a great post recently on connecting to the CLARiiON via serial cable. I was all set to do a brief howto article on the various connection mechanisms available on the CLARiiON for service activities and then figured out that the bulk of the work was done. So I thought I’d just add a note that, if you want to connect to the CLARiiON’s service LAN, here’s what you need to do. This is more for my reference, as I always find myself scratching around for the service LAN IP addresses.


vShield Clarification

A couple of weeks ago I wrote on vShield. As I said then, the Asia Pacific and Japan vSpecialists have spent a lot of time on this wonderful product. We love it. The purpose of my blog entry was to highlight a best practice that would avoid an annoying issue. That issue is that vShield App installation on ESX hosts running a vCenter virtual machine can disconnect vCenter from the network. The workaround–documented in the vShield Administration Guide–is to run vCenter and vShield manager on a management cluster. Case closed. Well, not yet.


Spring Reading Pre-Review

It’s that time of year again, when all the hard work various folks in the community turn into tangible products. In this round we’ve some second editions of some popular books. Let’s dive right in:

VCP4 Exam Cram

Elias Khnaser (@ekhnaser)


The VCP4 Exam Cram volume looks to be about the only game in town with regard to the VCP4. I’m not entirely sure why that is, but the book does a wonderful job of setting out each VCP4 Blueprint objective, and attacking it. It then provides sample Q/A you can work through. A desk reference, as well as a CD loaded with additional prep material.

Summary: An amazing little exam prep package for the price. Well worth your time if you will be taking the VCP4.


TIL – Snapshots Also Revert VM Settings

Actually, learned this one yesterday, but just got around to writing the post. I was actually clued into this by some friends in the UK.

According to these VMware docs:

An ESX snapshot contains the VM settings. Thus reverting it, will also revert this settings. Because I was under the opposite impression, I had to see for myself:


Crushing Urban Myths: VMware cost way too much?

I’ve done two articles for TechTarget that talk about VMware licensing. I think its a urban myth that VMware is an expensive option for SMB/SMEs. There’s been a lot of work in recent years by VMware to make it easier to consume the vSphere4 product, and last year they even altered the feature matrix of the Essentials Plus to allow SMB/SME customers to access features like vMotion and HA…

PowerCLI 4.1.1 poster - Updated

Pablo Roesch posted on the VMware Communities the latest version of the PowerCLI poster.


Snapshots are not backups

Well if you don't believe me, then believe VMware. There is official KB 1025279 -
Best practices for virtual machine snapshots in the VMware environment
(modifications are my own, refer to the original for the full article)

Snapshots are not backups.


Troubleshooting Performance Related Problems in vSphere 4.1 Environments

The hugely popular Performance Troubleshooting for VMware vSphere 4 guide is now updated for vSphere 4.1 . This document provides step-by-step approaches for troubleshooting most common performance problems in vSphere-based virtual environments. The steps discussed in the document use performance data and charts readily available in the vSphere Client and esxtop to aid the troubleshooting flows. Each performance troubleshooting flow has two parts:

How to identify the problem using specific performance counters.

Possible causes of the problem and solutions to solve it.

New sections that were added to the document include troubleshooting performance problems in resource pools on standalone hosts and DRS clusters, additional troubleshooting steps for environments experiencing memory pressure (hosts with compressed and swapped memory), high CPU ready time in hosts that are not CPU saturated, environments sharing resources such as storage and network, and environments using snapshots.

The Troubleshooting guide can be found here. Readers are encouraged to provide their feedback and comments in the performance community site at this link.


Management Cluster / vShield Resiliency?

4.1 cluster design vshield vSphere

I was reading Scott’s article about using dedicate clusters for management applications. Which was quickly followed by a bunch of quotes turned into an article by Beth P. from Techtarget. Scott mentions that he had posed the original question on twitter if people were doing dedicated management clusters and if so why.

As he mentioned only a few responded and the reason for that is simple, hardly anyone is doing dedicated management clusters these days. The few environments that I have seen doing it were large enterprise environments or service providers where this was part of an internal policy. Basically in those cases a policy would state that “management applications cannot be hosted on the platform it is managing”, and some even went a step further where these management applications were not even allowed to be hosted in the same physical datacenter. Scott’s article was quickly turned in to a “availability concerns” article by Techtarget to which I want to respond. I am by no means a vShield expert, but I do know a thing or two about the product and the platform it is hosted on.


E-Book version of the HA/DRS Deepdive?

I’ve had this question too many times over the last couple of weeks and instead of answering all of them separately I figured I would dedicate a blog article to it so that I can reference to that. Here we go:

Q) Will the e-book version of the HA/DRS deepdive be available soon?

A) No. We have decided that we will not release an e-book (including pdf, ibook, kindle) version of the book. It required a full reformatting of the book which is simple not feasible at this point in time. As it is a “self published” book we are responsible for not only the content but also the formatting etc. Sorry about that, for “Volume 2″ however we will reconsider this.


Anti-virus and the impact in virtualized environments

I was reading Richard Garsthagen’s article about anti-virus solutions yesterday and decided that this deserved a little bit of extra attention as it is an often overlooked area when it comes to architecture and impact. As Richard points out the difference in terms of load that it generates and overhead is enormous. All of these combined will most definitely result in an increase of consolidation ratio. Not only that but is will also seriously lower the risk during for instance a VDI boot storm but also think about the impact of HA initiated restarts. This could cause an enormous amount of IOps and CPU/Memory overhead which in its turn could impact the other virtual machines.


Blocksize impact?

I was answering a couple of questions on the VMTN forum and stumbled on the impact of using similar blocksizes for all VMFS volume which I never realized. Someone did a zero out on their VM to reclaim some wasted diskspace by doing a Storage vMotion to a different datastore. (Something that I have described in the past here, and also with relationship to VCB here.) However to the surprise of this customer the zeroed out space was not reclaimed even though he did a storage vmotion to a thin disk.


VMware Virtualization Management Blog: vCenter CapacityIQ 1.5 and Storage support

vCenter CapacityIQ 1.5 adds support for storage analytics and modelling that spans all three key use cases - analyze, optimize and forecast - of the product. This blog post provides details on these storage related enhancements in CapacityIQ 1.5.

CapacityIQ 1.5 tracks storage space used as well as IO throughput and latency. For storage space used, CapacityIQ provides further breakdown in terms of space provisioned, space used by VMDKs, snapshots etc. For both throughput and latency, CapacityIQ tracks read and write metrics separately. Furthermore, it tracks storage throughout in terms of IOPS as well as KBps. CapacityIQ 1.5 also adds trending and forecasting based on these storage metrics to provide time remaining information.

CapacityIQ dashboard and views have been enhanced to present all this storage anaytics. In the screenshot below, you can see storage metrics as part of the Resources section in CapacityIQ 1.5 dashboard.


Virtual Reality: 2010 – Another Great Year for VMware and Our Customers

The film industry awards season is just reaching its peak, but the software industry’s own Oscars for 2010 have been handed out and VMware finished up with another great year.  Here’s a sampling of the recognition VMware received from the IT trade press in 2010:

InfoWorld 2011 Technology of the Year – Best Virtualization Platform: vSphere 4.1 (7th year running!)

WindowsITPro Best of TechEd, Virtualization & Attendees Pick for Best of Show: vSphere 4  [The Attendees Pick award was especially notable since TechEd attracts exclusively hard-core Microsoft users.]

CRN Virtualization Product of the Year: vSphere 4.1 and vCenter 4.1

Network World Best of the Tests 2010, Server Virtualization: vSphere 4

eWeek Top Products of 2010: VMware View 4.5

Channel Insider Product of the Year: VMware View 4

Those same members of the technical press had some very nice things to say about VMware and our products in 2010:

“Microsoft won't come anywhere close to leapfrogging VMware in 2010” –

“VMware is in fact leaps and bounds ahead of competitors” – InfoWorld

“…the ESX feature set is substantially more mature…VMware remains the champ.” –InformationWeek

and my favorite…

“VMware is the king of virtualization. There is none higher.” – TechTarget


VMware vCloud Blog: Getting Started with vCloud Director, VMware Remote Console Proxy and VMware Remote Console Plugin

By Michael Haines, vCloud Architect

The Remote Console Proxy allows a tenant (a vSphere Remote Console client) using VMware vCloud Director (vCD) the ability to access a vApp (VM) and open and present the console of that vApp (VM) in question.

So, why do we need to have a Remote Console Proxy at all? In the context of VMware vCloud Director, we have a product that is designed to work over the public Internet. For security reasons, we need an intermediate communication module, the Remote Console Proxy. The security aspect and benefit here for the Service Provider means that they do not have to put their vSphere infrastructure directly on the internet, and for the consumers (tenants) of such a service, they gain the ability of access through an additional security layer such as a firewall, etc. 

Here’s How it Works:


VMware vCloud Blog: Getting Started with vCloud Director, VMware Remote Console Proxy and VMware Remote Console Plugin (Part 2)

By Michael Haines, vCloud Architect

In Part 1 of this post, I inroduced the components of the VMware console proxy, remote console proxy, and how they work with vCloud Director. In Part 2, I'll cover resiliency of the remote console proxy, what ports are required, operations available to the user, and run through troubleshooting and tools.


VMware ThinApp Blog: ThinApp package usage metering

Nicolas Van Wijnsberghe, a colleague of mine, sent me this great example of just how flexible ThinApp and its VB-Script support is. With our VB-Script your imagination is pretty much the limitation..


Here is a VB-Script that will provide a poor mans software-metering solution.


ESXi Chronicles: VMware ESXi: Planning, implementation and security

The week before VMware Partner Exchange I decided that it was time to start brushing up my ESXi knowledge. I usually dig up all the manuals and presentations I can find and start from there. This time I took a different approach however, I bought a book. The book was titled "VMware ESXi: Planning, Implementation, and Security" and was authored by a true VMTN Community hero, Dave Mishchenko.

I bought the e-book copy so that I was certain I could start reading during my flight 5 days later. But I was curious and I found myself flipping through the pages the very first evening and was almost half way through before my flight. I guess that says enough about the readability of the book. But readability/flow is not particularly why you buy a book. You buy a book like this because you want to know more about the subject, in this case ESXi. Dave's target audience is every person new to VMware and everyone who is considering migrating from ESX to ESXi.

VMware TAM Newsletter 3.04

Posted by nisserow Feb 17, 2011

Hi everyone, the year is flying by, I am already on the 5th newsletter of the year. This is a big one as it seems news and activity around VMware is really picking up now. The momentum is incredible and everywhere I look virtualization and cloud are the hot topics of the day. I don’t think that this will let up for some time due to the fact that this is still a fairly new experience for most and we are just beginning to get onto the maturity curve in terms of customer awareness and adoption. Those that are working on a fully virtualized strategy however have a significant advantage over the physical counterparts. Let’s be real for a second, no one expects large corporations, or even SMB’s for that matter to just instantly somehow shift their data, services, security etc. into the cloud. This is a process and one that starts with your own private cloud, virtualizing the data center and getting your internal IT to behave like a service provider for their customers (the rest of the business). This has great benefits for organizations and by implementing a private cloud they are well on their way to providing a full software as a service environment. Of course there is alot more to it than this but the core components have to be a fully virtualized environment.


A bunch of extra sections this week. Firstly last week’s KB articles are now being published. I will try and add these each week if they are available. I have also added a new section on Security which is a hot topic and one that I find extremely interesting especially in the world of virtualization.


Take care until next time

VCP4 Exam Cram: VMware Certified Professional (2nd Edition)

Tonight I was grateful to have received from Pearson Education the book VCP4 Exam Cram: VMware Certified Professional (2nd Edition).  The book is authored by Elias Khnaser (Twitter WWW) along with Technical Editors Brian Atkinson (WWW) and my friend Gabrie van Zanten (TwitterWWW).  This 2nd edition is 340 pages in length and ships with a cardboard fact filled cram sheet in the front as well as a CD in the back which contains VCP4 practice exams and an electronic versions of the cardboard cram sheet in case your friends are jealous of your intimate VMware vSphere knowledge and decide to swipe yours.

The book (ISBN-10: 0789740567) includes 10 chapters along with an appendix.  The chapter layout is as follows:


Windows 7 Update Breaks VMware View Client: An Important Lesson In BYOD

Many customers I talk to are interested in supporting a bring-your-own-device (BYOD) delivery model. A thought frequently echoed by customers is that allowing users to access their applications on their terms improves mobility and leads to greater productivity. In addition, when personal devices become little more than a tool to access IT applications centrally stored in the data center or in the cloud (e.g., SaaS), we also realize the following benefits:


New book about vSphere Design preorder

New book will hit the Amazon store soon.

New vSphere Design Book from some well known faces in the VMware community. The new book is a joint project of 3 persons: Forbes Guthrie, Scott Lowe, and Maish Saidel-Keesing. All those guys are also bloggers. This is a first book which is oriented VMware vSphere design. It’s a great initiative, since there is quite a few books now very high quality telling us and teaching us how to do this or how to use that feature, but to think desing before the actual implementation, there are not so many.


Zimbra 7.0 is out

Zimbra 7 collaborative suite togegher with Zimbra Desktop 7 (beta) was released.

Today, just now the new Zimbra Collaborative Server 7 (ZCS) was released. Not so long time ago I reported on a sneak peak at Zimbra 7.0 Beta…. The time just run too fast.. The Zimbra Desktop (in Beta for now) is and will stay Free.

The new Zimbra is available as an OVF which can be deployed in your datacenter in minutes. See my article on deploying Zimbra OVF here…

Zimbra Integrates perfectly with Microsoft Outlook on the desktop side…


VMware Desktop Certification announced

The times when there were only one certification from VMware are gone. Sure there were always VCDX. But now not only VCP, VCAP-DCA, VCAP-DCD, but also VCA4-DT…..

As spotted on Eric’s blog today (as usually He got the latest informations first and for us the rest of our poor bloggers we try to limit the damages…. -:)…). VMware has announced the availability of Desktop Certification – The VMware Certified Associate 4 – Desktop (VCA4-DT).


Switch from RDP to PCoIP with a nice drop in the WAN network traffic

In this video from VMware TV you’ll see a VMware client using VMware View 4.5 in a heath-care environement.

A quick video about using VMware View for Virtualizing Desktops in medial care institutions.

What took my attention was the fact that when they swapped from classic RDP sessions to PCoIP provided by VMware View Virtual desktops, they saw a big drop in a WAN traffic – about 2/3rd….. In fact with more devices used in the medial institution, there were less traffic in the network.


Save [VDI] Storage using VM Swap File Host Placement

When designing VDI solutions for VMware infrastructures, one of the many ways to reduce shared storage consumption is to allow the placement of VM Swap files (.vswp) on host local storage. The .vswp file is automatically created by ESX when the VM is Powered On, and automatically removed when the VM is Powered Off.


VDI Flash Calculator v2.0 Released

I have just uploaded a new release of the online VDI Flash Calculator.

This release include a cool new feature – the ability to offload VM Swap Files to Local Storage. Many of my solution designs utilise local storage for VM swap files in order to save shared storage. I’m uploading this new release with an article discussing the benefits and downsides of VM Swap file in Local Storage. Read at Save [VDI] Storage using VM Swap File Host Placement.

Another nice feature is the ability to add high availability to connection servers.

The VDI calculator can be found at Alternatively, go to my blog homepage and select VDI Calculator on the top bar.


VDI and Microsoft Outlook, analysing the variables

VDI is a multitude of technologies that must work together in a premeditated way; and this we already know. However, couple weeks ago an interesting discussion in one of VMware’s internal forums sparkled my attention. The topic demonstrates clearly the level of attention and detail that a good VDI design should have. The central point of the question was about Microsoft Outlook configuration for VDI environments. Sounds simple, but let’s have a look.


VCAP-DCA Prep Video - Implement and Maintain Complex VMware HA Solutions

In this video I'll show you how to manipulate the slot size in a VMware vSphere HA cluster. You can set advanced attributes that affect the behaviour of your VMware HA The cluster.The das.slotMemInMB advanced value defines the maximum bound on the memory slot size. If this option is used, the slot size is the smaller of this value or the maximum memory reservation plus memory overhead of any powered-on virtual machine in the cluster.


VCAP-DCA Prep Video - Configure SNMP for ESX/ESXi

ESX/ESXi includes an SNMP agent embedded in hostd that can both send traps and receive polling requests. such as GET requests. This agent is referred to as the embedded SNMP agent. By default, the embedded SNMP agent is disabled. To enable it, you must configure it using the vSphere CLI command vicfg-snmp. In this video I'll show you how to enable the SNMP agent.



The bridge to the cloud - The vCloud Connector

VMware has announced a new free product which enables you to move and control your virtual machines and vApps in the cloud. The vCloud Connector will be available for download in Q1 2011.


Getting Started with SUSE Linux Enterprise Server for VMware

Alberto Farronato reports: SUSE Linux Enterprise Server For VMware Now Available To Many More VMware vSphere Customers - I am very happy to share some very exciting news for VMware vSphere customers: SUSE Linux Enterprise Server for VMware - VMware’s OEMed version of Novell SUSE Linux Enterprise Server (SLES) - is now available for free to customers with qualifying VMware vSphere licenses regardless of when these licenses were purchased.


My VCAP-DCA Exam Experience

Today I took my VCAP-DCA exam over at Global Knowledge in Nieuwegein. I had to complete approximately 40 assignments ranging from easy to ones I really didn’t know or had the potential to consume a lot of time. If you encounter a question you get stuck on, just write down the number and hop over to the next assignment. I  was able to complete the assignments with one hour left, but I skipped 10 questions. In the end I managed to complete 4 of those 10 when the exam ended.  The prep material I’ve used is:



VMware – SRM advanced setting for snap prefix 8/02/11 7:34 AM dan SRM VMware Advanced ESX ESXi mirrorview san snap srm SRM4 virtualcenter virtualisation


We haven’t been doing this in our production configurations, but if you want to change the behaviour of SRM with regards to the “snap-xxx” prefix on replica datastores, you need to modify an advanced setting in SRM. So, go to the vSphere client – SRM, and right-click on Site Recovery and select Advanced Settings. Under SanProvider, there’s an option called “SanProvider.fixRecoveredDatastoreNames” with a little checkbox that needs to be ticked to prevent the recovered datastores being renamed with the unsightly prefix.


Physically Separate Management Cluster

My recent foray into the world of vShield produced a contention recommendation from my friends at VMware. Today I want to ask you to educate me and our peers. I want to know: do you think it is a best practice that management products should be run on their own in a vSphere cluster?

The recommendation that all management products should be placed in a separate physical cluster came from friends at VMware that I greatly respect. This guidance was raised as the properworkaround to the “vShield App will kill vCenter networking” issue. With vShield only managing test and production clusters and vCenter running in a separate management cluster, the network-killing circular dependency between vShield and vCenter is avoided.


vCenter out of Space! – A Lesson on Shadow Copy

Ran into an issue today where my vCenter would not come back up after a reboot. Standard troubleshooting ensued… the DB is up, it is accessible, odbc is Kosher, etc. At that point, Windows helpfully popped up a message balloon: “I pity the fool who runs outta disk space!”

So I dug, and a dug… and the numbers were not adding up… the system folders, vCenter folders, etc only accounted for ~2GB of a 50GB disk. So where was it?

That’s when I found this helpful gem:


VMware View 4.5: Rebalance

Rebalance: A desktop rebalance operation that evenly redistributes linked-clone desktops among available datastores.

When testing this, customers can often see unexpected results. This is often due to their misconception of how this function of View works.


Get Rid of those ESXi Tech Support Mode Warnings

One nice enhancement in VMware ESXi 4.1 is Tech Support Mode — supported command-line access for advanced troubleshooting.  However, a big drawback of enabling this capability is the appearance of a new Configuration Issues warning in the vSphere Client:


SLES for VMware Entitlement Expands Broadly

Great news for long-time VMware vSphere customers:  the free SLES for VMware entitlement is now retroactive for almost all customers currently active on vSphere 4.0 U2 or later.

When initially announced last year, access to SLES and ongoing patch downloads were offered to customers that purchased vSphere after June 9, 2010.  With this recent change, VMware is extending rights to SLES for practically all customers current on SnS.

Please see the official VMware announcement for all the details.



I got an email from Chris Dadswell who has created a really cool Mind Map based on the VCAP-DCA blueprint.

I recently started using mind mapping for more things so if you are interested you can check it out at


Automated support bundles

I received an email recently from a gentleman asking if it was possible to export the support bundles for each host on a daily basis, this can be useful for not only having an archive of your system logs to help resolve problems and work out when they started but also useful for auditing purposes.

At the moment he was doing this manually every day by using the virtual infrastructure client as can be seen below – you can imagine how long this was taking !


The Cloud…now closer than ever!

Today VMware announced the intent to release vCloud Connector before the end of Q1 as a free download to it’s vSphere customers. So what is vCloud Connector you ask? Well, it is a huge leap forward in making the Hybrid Cloud concept a reality. vCloud Connector is a plug-in that you install into your vSphere Client, it will allow you to easily move your virtual machines from your local/trusted/secure datacenter (Private Cloud) to the dynamic/scalable/on-demand Public Cloud while never leaving the vSphere Client, in fact you can still manage those virtual machines that moved over!


VMware vCloud Director 1.0 Performance and Best Practices — Paper Published

Do you want to know how many VMware vCloud Director server instances are needed for your deployment? Do you know how to load balance the VC Listener across multiple vCloud Director instances? Are you curious about how OVF File Upload behaves on a WAN environment? What is the most efficient way to import LDAP users? This white paper, VMware vCloud Director 1.0 Performance and Best Practices, provides insight  to help you answer all the above questions.


Using the vSphere Plan & Design Kit

As part of my role I very often review design documents that other consultants/architect have written, and not only those of VMware employees but also from external people. On top of that of course I also see a lot of VCDX application packages pass by. Something struck me the other day when I was doing the 3rd review in just a couple of hours and I started thinking about the designs I had reviewed so far and noticed there was a common theme.


Storage Performance

This is just a post to make it easier finding these excellent articles/threads on VMTN about measuring storage performance:

Scott Drummonds – Storage System Performance Analysis with Iometer

VMTN Unofficial Storage Perf Thread I –

VMTN Unofficial Storage Perf Thread II –

All these have one “requirement”  and that is that Iometer is used.


VMware vCloud Blog: When Your Data Center Has Packed Its Bags

I recently grabbed lunch with a friend of mine whose company had just moved their data center several states away.

Physical Data Center Migrations such as these are truly epic quests: one hopes that servers come off the trunk in roughly the same shape they possessed when they were placed on the truck. Once the gear is brought into the new data center you try to re-assemble all the building blocks in the same manner as the original datacenter.

Carefully and in the proper order, one powers on servers one-by-one hoping that disks haven't been jostled and all networks were reconstructed correctly. Of course the data center reconstruction didn't go entirely to plan and the poor guy spent most of his holiday trying to get his services to start up once again. Physical servers and networks can be very delicate items that require a good deal of precision to move, no matter if it is three yards or three states.

Virtual Datacenter Migrations


VMware ThinApp Blog: Launching a ThinApp Packaged App in Windows Compatibility Mode

Recently we were asked again about being able to launch a ThinApp packaged application in Windows Compatibility Mode. While VMware Community Member EuwRhU posted a script on how to do this here (Thanks EuwRhU!), I wanted to capture this knowledge in one location here on the ThinApp Blogs as we've been asked a number of times since EuwRhU's posting on how to do this.

Well my vegas trip is over and I am back in Brisbane after an incredibly interesting and successful trip. I am so luck to work for a company like VMware that has so much faith in it’s employees. We have such amazing leadership, vision, technology and passion for what we do. I feel privileged to be able to work with such smart and dedicated people. This week I will be kicking off a new section which will hopefully increase the newsletter’s content and usefulness for all of you. The new section will include information that is put together by a number of key internal employees, however all of this information is of course public or opinion based. I hope that you enjoy this new section.


Disaster Recovery:

As many of you are aware the recent floods in Queensland and now cyclones in the far north of the state have caused major damage. One of the key topics that comes up during these times is how robust is our disaster recovery strategy. While this is something that should be considered all of the time during times of catastrophe these procedures are scrutinized and often put into action during this time. As VMware customers I urge you to discuss your current DR strategy in it’s entirety with your TAM with special regard to your virtualized environment, highlighting areas of risk and concern.


From next week in Brisbane we will also be starting the Lunch and Learn sessions again. This is a series of very informative technical sessions which are presented by our System Engineers and Technical Specialists on a variety of topics. The newsletter will always contain details on the upcoming session at the end of the newsletter. Please note that unless otherwise indicated all sessions take place at the Brisbane VMware office.


I hope that you all have a wonderful week ahead


Best Regards

Neil and Paul

Tips and Tricks how-to best manage Memory under VMware vSphere

There is new how-to Whitepaper from vKernel written by Jonathan Klick, which gives you some interesting ideas on the memory management in your vSphere Infrastructure. You can get the Free White Paper at this address.

This white paper provides information on the key memory metrics you should use for VM (virtual machine) memory allocation sizing and performance issue monitoring, as well as recommendations on how to make these assessments when large memory pages are in use.


Check alignement and Wasted Space with free tool from VirtualizePlanet

Free tool to check alignement of your VMs and also Wasted space on your VMDKs.

Ricky El-Qasem from has build a nice free tool which enables you to check the alignements of your VMs in the cluster and also check wasted space in your VMDKs. It’s 2 in 1 tool. I was actually participating in the building process, since I did some beta testing for Ricky. Not only me, but also other bloggers too. It was fun.

It’s a tiny package to download (2.6 Megs) . Make sure that you have .NET installed on your system otherwise during the installation process the latest .NET will be downloaded and so the installation process can get lengthy.

How to use it? Very easy. Just check the About button on the software. You’ll see a nice page where you can see the instructions….-:). Basically just click on nice VMware Tree button on the left top side of the program, where you enter your vCenter or ESX(i) credentials, and here you go. Next thing you must do is to go to Scan Options button, where you enter your Domain credentials which might be different from your vCenter credentials.


APAC Virtualization Roundtable (SNIA with @Rodos) – Wed 2/2

This week megastar Rodney Haywood (@rodos) hosts the show interviewing Paul Talbut from SNIA.

SNIA lead the storage industry worldwide in developing and promoting standards, technologies, and educational services to empower organizations in the management of information. Hear from local SNIA general manager Paul Talbut about SNIA in Australia, what they do and what’s planned for this year.

If you interested in joining the APAC Virtualization Roundtable initiative to host or guest an episode please reach out to me or Alastair Cooke.


Load Balancing Health Monitoring Traffic

For the purpose of hardware sizing one of my customers asked me about the amount of bandwidth traffic that is required by Load Balancers in order to maintain a constant View health monitoring.

The most common types of health monitoring are ICMP and HTTP.

HTTP health monitors are optional in a VMware View deployment, however strongly recommended. The Load Balancer appliances issue a GET URL command to retrieve the index.html page from each connection broker in the pool.

When the Load Balancers probe a Security Server, the Security Server immediately performs a check against the Connection Server for which it is configured. This check between the Security Server and Connection Server  happens over the AJP13 (TCP 8009) connection.

The picture below (if you can read) demonstrate a WGET command issued against a connection broker – for VMware View 4.5 the index.html is 1.2K.


VMware vSphere Design - The only book to cover how to properly design a VMware vSphere 4 implementation

VMware vSphere is the industry’s most widely deployed virtualization solution. The current release VMware vSphere 4 is considered the most robust and sophisticated virtualization product. This book is the only one of its kind to clearly and concisely show you how to create a vSphere 4 implementation so that it is tailored to meet a company’s needs and resources. Expert authors share with you the factors that influence and shape the design of a vSphere 4 implementation. You will learn how to make the right design decisions for your company.


Technical Papers: SAP Solutions on VMware vSphere 4 - Best Practice Guidelines

This paper provides best practice guidelines for deploying SAP® software solutions on VMware
vSphere 4. These guidelines only provide general recommendations and do not target any specific size or type of SAP solution implementation.

VMware has created separate best practice documents for the individual areas of storage, networking and performance. (See the Resources section for a list of these publications.) SAP also has created a variety of technical notes, published in the SAP Marketplace, for more information about virtualizing SAP solutions on VMware virtual infrastructure. Reference numbers of these notes are identified in this document, and you can refer to these additional technical notes in conjunction with the information provided here.


vShield, vCenter, and Management Clusters

I recently tweeted looking for VMware customers using the vShield products in production. There was very little response. It seems that vShield Edge and App are barely being used at all in production. It is possible that some rough patched need to be sanded down to polish vShield to its appropriate luster. But if you are not playing with these products now, you owe it to yourself to download the trial versions.

Our fantastic APJ vSpecialist organization has been spending with vShield. Many of us believe vShield to be one of the most exciting editions to the VMware portfolio in a long time. It is simple, elegant, and very powerful. But there is a very big danger with vShield: improper use can disable the network connection of vCenter virtual machines. Fixing this problem is not intuitive.


Cannot start a Virtual Machine

I was presented with an issue yesterday regarding a VM that I was not able to start

I went through KB Article 10051, step by step, until I got to:


VMware View Desktops: IDE or SCSI? BusLogic, LSI Logic or PVSCSI?

BusLogic IDE LSI Logic PVSCSI SCSI vdi view

I've seen and had many discussions around this topic when discussing VMware View desktop design, so I though I'd gather as much information as I could to help you decide.

From the information below, I would personally recommend using the following:

Windows XP: LSI Logic Parallel or SAS

Windows 7: LSI Logic SAS

The PVSCSI controller will be the controller of the future so you may also want to keep this in mind. Of course you can make your own decisions. Most of the points made are desktop focused, however most will apply outside of a View environment.


The VCAP-DCA Study Guide Lives On

I had previously stated that I would no longer be keeping up with the VCAP-DCA study guide I had created and that will still stand true, however I have found someone else to take over updating it. Damian Karlson whose blog you can find at has stepped up and volunteered to take over keeping the guide up to date. Damian has a great knowledge of VMware and as someone who is pursuing the exam will be able to give the guide the attention it needs.


ESXi Chronicles: Scripted install with ESXi

I received a couple of questions around doing a scripted install with ESXi and decided to write up a script and show you the steps required. Doing a scripted install with ESXi though is fairly simple:

Boot from the ESXi CD-Rom

Press "Tab" when the "VMware VMvisor Boot Menu" is displayed

Edit the  string so that it includes the location of your script.

When including the location of your script make sure you append it after "vmkboot.gz" and before "--- vmkernel.gz" as William Lam pointed out in his blogpost. It should resemble the following screenshot.


VMware Support Insider: Cannot power on any VMware View virtual desktop in pool

Another in our Resolution Paths series, here is a ResPath article for those of you who use VMware View. Recall that a ResPath article outlines a step by step process to resolving an issue.

Let's start by looking at the Respath titled: Cannot power on any VMware View virtual desktop in pool

You'll be interested in the KB article if:

You cannot power on any virtual desktop in a pool, or,

You are having power on issues with your View virtual desktops


VMware Support Insider: VSphere Hypervisor licensing

Today we have a guest post from Ganesh Shetty, who is a Tech Support Engineer in our Bangalore office who specializes in Licensing issues. Today, he answers some very frequently asked questions about ESXi, or as it now known, vSphere Hypervisor.

If you are planning to install vSphere Hypervisor (formerly known as VMware ESXi Single Server or free ESXi) soon, here is some licensing information that may be helpful.

The free vSphere Hypervisor Serial Key that you receive can be used to license any number of standalone ESX hosts as long as they don’t exceed 100 physical servers. We get a lot of questions on this.

Another commonly asked question is what features does vSphere Hypervisor contain?

Secure Remote Access with View and PCoIP

13/12/10 6:14 AM by Mark Benson

View Security Server is a component of View that is typically deployed in a DMZ to support remote access to virtual desktops. When accessing desktops from the Internet, such as by the home or mobile worker, Security Server provides the required level of security and connectivity. It ensures that the only remote desktop traffic that can enter the corporate data center is traffic on behalf of a strongly authenticated user. It also ensures that the user can only access desktop resources they are authorized to access.

VMware SRM with CLARIION SRA Gotcha

07/01/11 6:50 PM by Brian Norris

I was working on a VMware SRM with EMC CLARIION implementation when I come across another gotcha and thought id post about it.  I had to change the IP Address’s for the CLARIION management ports at the DR site and with doing so I went into SRM and edited the array manager configuration so the DR array information used the new management IP Address’s for SPA and SPB.  After performing a rescan of the storage and getting a hideous error, I went looking in the logs and found the following error.

Presentation on VMware vSphere 4.1 Storage Features

29/01/11 3:58 AM by Scott Lowe

EMC - vSphere, RecoverPoint, and Business Continuity for Microsoft Exchange 2007

08/10 by EMC

This detailed whitepaper documents the testing and validation of the disaster recovery capabilities of VMware vCenter Site Recovery Manager with EMC RecoverPoint, and EMC Replication Manager in a Microsoft Exchange 2007 environment.  Testing included validating the performance of 4000 very heavy Exchange 2007 users when replicated to a remote site 100km away using asynchronous RecoverPoint.  Using this configuration, both Microsoft Jetstress and Microsoft Load Generator were used to validate the performance of Exchange 2007.  All Exchange performance metrics fell well within the guidelines provided by Microsoft.  Recommended reading for all customers interested in BC regardless if you are an EMC customer.

The VCE Model: Yes, it is different         

22/01/11 by Nicholas Weaver

This post comes out of a slide deck I authored last week for a partner event. I decided I was going to try and illustrate why the VCE model really is such a different approach to other datacenter and private cloud models.  Normally my blog is light on vendor specific commentary. I see myself more as a virtualization geek who just happens to work for an awesome company (EMC) than a hardcore analysis/blogger. But I have seen so much messaging lately that distorts the VCE message, I really felt the need to offer my own perspective.


For background, Virtual Computing Environment (VCE) coalition is an unprecedented collaboration of three information technology (IT) industry leaders (VMware, Cisco, and EMC) focused on helping customers build a Private Cloud though a shared vision using aligned products and technologies. The coalition has been created to accelerate the customers’ ability to increase business agility through greater IT infrastructure flexibility, and lower IT, energy, and real estate costs through pervasive datacenter virtualization and a transition to private cloud infrastructures.  With the VCE strategic alliance providing reference architectures, solutions, and services, market adoption of virtual datacenter architectures can be increased with less risk and greater reward to enterprises and IT organizations. VCE also offers a joint vision, technology development roadmaps, integrated transformation services, and solutions that will reduce the time needed for a customer to realize business value. Over the last six years VMware, Cisco, and EMC have been developing this alliance through partnerships to lead the effort in the virtualization of datacenter architectures. VCE solutions, consumption types, and technology development work streams have been created specifically for this initiative, as well as reference architectures that have been defined and tested.  Check out the VMware Reference Architecture for Cisco UCS and EMC CLARiiON with VMware View 4.

Generating Load to Test DRS

03/02/11 by Duncan Epping

Every once in a while you would want to stress a VM or multiple VMs to test the working of for instance VMware DRS. There are multiple tools available but most of them only focus on CPU and are usually not multithreaded. My colleague Andres Mitchell developed a cool tool which will load a multithreaded CPU load and will generate memory load.


Alternatively, remember the CPU Busy script from the VMware VCP410 course – Refer

View 4.5 - Install and Configure Article Series

15/09/10 by Paul Slager

While I was at VMworld a few weeks ago VMware announced its latest release of its virtual desktop platform, VMware View 4.5! I have been closely watching the VDI market this past year but haven’t felt compelled to start doing any thorough tests because of several issues. First there was a battle over which protocol would reign supreme. I didn’t want to jump on any technology before that issue was clearly sorted out. Second, most of our users are laptop users and the offline desktop feature now called local mode was seriously lacking some luster. Third, I was waiting to perform a Windows 7 upgrade in alignment with the Virtual Desktop Project. Finally I wasn’t sure that the cost savings were quite there yet after performing a few preliminary TCO’s.


I believe that VMware has sorted out the protocol issue by implementing PCOIP and RDP. PCOIP still has issues over the WAN just like any of the other protocols that have come out but it’s much more efficient then RDP. Local desktops have been vastly improved and now you can even have your linked clones go “offline”. I am currently preparing for a Windows 7 upgrade so now is as good as time as any. Hold tight because this is going to be quite a ride. A virtual desktop project is no small project. I truly think that you need to put more effort and planning into this than you did with your server virtualization project. Part 7 of the series, ” VMware View 4.5 Planning & Implementation”, will bring to light some of the key factors in your decision making process to help you plan your project.


This ten part series is in no way an exhaustive guide, as too many variables exist. However, if you have questions about something that I didn’t write about please ask and I will help you as best as I can.

VMware TAM Newsletter 3.02

Posted by nisserow Feb 4, 2011

From the editors Virtual Desk


Hi everyone, this week’s newsletter comes to you from Las Vegas where I am attending a VMware employee conference. Of course it is also great that this conference is being held in Las Vegas. There are a number of new additions to the newsletter which I will be bringing you starting next week. With the help of my TAM colleague Paul and some of the wonderful folk at VMware who are always sending us useful information we have included much of this in the newsletter this week. Of course we have only included news that is of public interest but due to the source of this we feel that it is a great addition to our newsletter and we will try and include this type of information as often as possible.


To all of my TAM customers I look forward to seeing all of you next week when I am back and hopefully talking to you about some of the exciting new technologies that we will be bringing to the world of virtualization in the near future.


Have a fantastic week everyone.


Best Wishes

Jumbo Frames Comparison Testing with IP Storage and vMotion - VMware Virtualization Evangelist 25/01/11 12:03 AM jason Virtualization Hardware Networking VMotion VMware vSphere

Are you thinking about implementing jumbo frames with your IP storage based vSphere infrastructure?  Have you asked yourself why or thought about the guaranteed benefits? Various credible sources discuss it (here’s a primer).  Some will highlight jumbo frames as a best practice but the majority of what I’ve seen and heard talk about the potential advantages of jumbo frames and what the technology might do to make your infrastructure more efficient.  But be careful to not interpret that as an order of magnitude increase in performance for IP based storage.  In almost all cases, that’s not what is being conveyed, or at least, that shouldn’t be the intent.  Think beyond SPEED NOM NOM NOM.  Think efficiency and reduced resource utilization which lends itself to driving down overall latency.  There are a few stakeholders when considering jumbo frames.  In no particular order:


VESI and PowerGUI going to merge

ESX Virtualization 24/01/11 10:35 PM Vladan SEGET Free Stuff PowerGui scripting VMware VMware Power Pack


Vesi and PowerGUI will become one tool. In fact the efforts are made to maintain unique platform only and merge those 2 projects.

What now? Many vSphere administrators now still have the possibility to use PowerGUI which is another graphical user interface which can be used to run, create and test new scripts. Very popular VMware Power Pack can be used with PowerGUI. Dimitry Sotnikov who is the person in charge of PowerGui, and I already reported about this tool here and here, has informed about why the process of merging those 2 projects.

It’s an unique free tool which is helpful not only for vSphere environments, but there are also PowerPacks for Hyper-V, Active Directory, Exchange Server and others…. See how the PowerGUI can help you with daily tasks of maintenance, reporting etc….

Top 20 vCenter Performance Metrics to Care About

NTPRO.NL - Eric Sloof 26/01/11 6:31 PM (Eric Sloof) Online Training

With virtualization come management challenges. Now that applications compete for shared, dynamic infrastructure resources such as storage, memory, and CPU, an inevitable resource allocation problem arises, that if not addressed will impact the performance of both VMs and their associated applications. This presentation discusses the 20 metrics that truly matter in vCenter to evaluate and manage this situation.


VMware – Installing APC PowerChute Network Shutdown 24/01/11 8:30 PM dan ESX ESXi VMware apc PCNS PowerChute virtualisation


I’ll admit I haven’t had to install APC’s PowerChute Network Shutdown product on my ESX(i) hosts lately, as the kind of DCs I’m hosting stuff in doesn’t cater for the UPS in a rack scenario. That said, I’ve had the (mis)fortune to have to install and configure this software in years gone by. As luck would have it, VMware published a KB articlerecently that points to APC’s support website for information on the how and what. There are two PDF files on the APC support page – one for ESX and one for ESXi. So, if you’re into that kind of thing, then you should find this useful.


Revisiting Snapshots from ESXi (TSM) Tech Support Mode

We’ve covered snapshots here a few separate times in past. However most of these were focused on ESX classic or preforming the work using one API or another. As VMware is making the shift to ESXi, it makes sense that you will need a way to deal with snapshots from the ESXi console (aka TSM/Tech Support Mode).


The Future of SRM – Part Deux

RTFM Education 27/01/11 1:23 AM Mike Laverick SRM

This little missive concerns other functionality of SRM which we may see in the future… It’s much more general than the 1st part which focused on VMware’s HBR (Host Based Replication) technology. You can see some tantalizing hints at the future direction of SRM such as being a tool facilatate site migrations, perhaps even been used as engine to move VMs into the cloud. I also take a peek at some of improvements in re-IPing virtual machines, and VM Groups.


Uptime: New Hardware Can Affect TPS

I recently deployed some new hardware in my lab and to my surprise discovered that after moving several VMs to the new hosts their memory utilization went up.  I also noticed that Transparent Page Sharing (TPS) wasn’t working on these hosts.  This didn’t make sense so naturally I did some digging and I want to share with you what I’ve learned as I know I’m not the only one upgrading hardware and many of you will likely stumble onto this same issue.


VMware vCloud Blog: Cloud Architecture Patterns: VM Template

VMware Blogs 25/01/11 3:14 AM

By Steve Jin, VMware R&D


Standardize new virtual machine provisioning with templates


Creational pattern


It’s been a pain to create new virtual machines with the right software installed and configured properly. You can always use tools like KickStart to automatically install the operating system and then install other software as needed. But configuring such an environment is not trivial, and it takes a long time from start to finish.

With the rise of virtualization, more virtual machines are provisioned (and decommissioned) than ever before. Installing each new virtual machine from scratch is not the ideal solution.


While virtualization highlights the provisioning problem, it also offers an easy solution. It’s called a virtual machine template. You can pick and configure every piece of software you will need into a template, and clone it to new instances whenever needed. It’s not only easier but also much faster.


ESXi Chronicles: Adopting ESXi, now is the time!

VMware Blogs 25/01/11 3:47 AM

Within the virtualization community we have been seeing more and more people adopting ESXi. Not only adopting it but also actively evangelizing the use of ESXi over ESX classic. The main argument being of course the reduction in operational effort involved with maintaining the platform. Last week two excellent articles were published. The first article was by Bob Plankers of fame. Bob wrote an excellent article countering all often heard complaints about ESXi.

Announcing VMware vSphere Design 1/02/11 12:00 AM slowe Collaboration Virtualization VMware vSphere Writing

This is a joint post of three prominent writers in the virtualization community: Forbes Guthrie, Scott Lowe, and Maish Saidel-Keesing.

For the past 6 months we have been working on a joint project. It has actually been kept pretty quiet, and it is now time to make this public.

Previous VMware vSphere books have focused on how to master the technology, deep-diving into certain elements and giving tips & tricks that help you manage your virtual infrastructure.

But we felt there was something missing in all these books. What was missing was how to design an infrastructure, accounting for all the elements that you need to consider. For example:


Failed to activate the software license workaround #VMware #View

vFAIL.NET 27/01/11 10:19 PM Sean Crookston VMware view KMS MAK VMware View




Recently I was setting up a VMware View in my home lab and came across this error, which I had seen before. The error occurs because a KMS server is not properly setup to activate the Windows 7 linked clones. As result I could not access any of the linked clones I created .

I don’t need these machines for any reason other then to play around with different options for linked clone pools so I began looking for a work around to this issue and found one here. In the base image you created, you would have installed the VMware View Agent. On that system you will find two registry keys of interest that you may want to modify. As stated, this is not supported by VMware but may be good for proof of concept or demo purposes as getting a KMS server can sometimes be difficult to get set up in certain


How long does it take to become a VCDX?

vFAIL.NET 1/02/11 4:00 AM Sean Crookston VCAP-DCA VCAP-DCD VCDX VMware vcp



I recently have received a couple of questions regarding how long it takes to get the VCAP-DCA and a while back someone even asked how long the whole process to become a VCDX might take.

The purpose of this blog entry is not to answer the question but to discuss what it takes for each step, although I will try and explain what time I have taken on the steps I have completed thus far.  I have an idea in my mind when I would like to do certain parts of the path but the true answer will depend on when I feel I am ready. For purposes of simplicity and the fact the VCDX3 has only one last defense possibility(I believe), this will focus strictly on those who are not a VCDX 3 already and are pursuing the VCDX 4. As I have only gotten as far as getting my VCAP-DCA, I hope to update the latter part of this entry with more of my experiences.

Uptime: Tuning the DRS Migration Threshold

VMware Blogs 1/02/11 1:58 AM

I often get asked for advice on tuning the DRS migration threshold, and my standard answer is to stick with the default.  However, I can appreciate that when you provide a nice looking slide bar with five possible settings there is a natural tendency to want to change things, and trying to convince people to resist this urge requires a bit more than a simple “stick with the default”.  So let me explain why, in most situations, keeping the default migration really makes sense.


Uptime: PSODs and VMware HA

VMware Blogs 1/02/11 9:22 AM

Despite our best efforts here at VMware, there are occasions where a PSOD may occur.  PSODs can occur for a wide range of reasons, including out of memory and hung CPU conditions.  In a HA protected environment, if a PSOD does occur you would expect that the VMs that were running on the host that encountered the PSOD would be failed over to another host.  There does exist a corner case where this may not be the case.  Let me explain why:
