Adding a PowerShell Windows Update Script to my VMware Customizations

In my environments, we typically convert the templates to Virtual Machines once a quarter so we can install Windows Updates.  This means, there could be a number of patches to install if you’re 2+ months out from the last time they were updated.  So I decided to use a PowerShell script that my coworker wrote to do Windows Updates and run it during the Run Once phase of the vCenter Customizations. Typically, I have my customizations set to automatically login

Perception is Reality When Virtualizing Business Critical Apps

It’s been too long since I’ve blogged anything on a regular basis.  Sorry about that.  I would love to blame it on the three books I’ve written in the last year but that isn’t the only reason.  Hopefully I can turn it around and start writing on a regular basis again. I’ve been sitting on this one for a while but finally had some time to get it down.  When it comes to virtualizing business critical applications, the perception of

Microsoft removes SVVP Support Policy Wizard..and I think it’s a good thing

Microsoft first released the Server Virtualization Validation Program back in 2008 to help validate their products running on server virtualization technologies (both Microsoft and 3rd party).  Followed soon after that release was a tool called the SVVP Support Policy Wizard which made it very easy to simply plug in your application, OS version, and desired hypervisor and out would come a support statement. Recently Microsoft removed the SVVP Support Policy Wizard and replaced it with a more generic support stance

Virtual machine snapshots and tier-1 apps: Not always supported

After seeing a discussion in the vExpert forums and in my own experience in talking to customers, I came to the conclusion that many people aren’t aware of some of the support restrictions around virtualizing tier-1 Microsoft applications. The one support requirement that many folks aren’t aware of is the use of virtual machine snapshots on Microsoft applications, particularly Exchange or SQL.  For both applications, Microsoft is explicit in stating that virtual machine snapshots of any kind are not supported.

Guest clustering on vSphere: A familiar topic revisited

Yes, it’s 2012 and we’re still talking about whether or not organizations should consider running a Microsoft Windows Failover Cluster (sometimes referred to as MSCS clustering) in a vSphere environment.  I know this topic has been written about before by others but I wanted to share some of my own thoughts and experiences around this topic.  My focus these days is helping organizations virtualize their mission critical applications, and in that pursuit the topic of guest clustering comes up often.

New SQL 2012 Licensing and Its Impact On Virtualization

Last week Microsoft released their updated licensing scheme for SQL Server 2012, which is due to be released next year.  Though there are a number of changes to the product and to how it is licensed, in my mind the biggest change is that Microsoft has moved to a per core licensing model for SQL.  The Server + CAL model still exists as well but for this post I’ll focus on the per core licensing and changes that affect those
