Best Practices: running vCenter virtual (vSphere)

Yesterday we had a discussion on running vCenter virtual on one of the internal mailinglists. One of the gaps identified was the lack of a best practices document. Although there are multiple for VI3 and there are some KB articles these do need seem to be easy to find or complete. This is one of the reasons I wrote this article. Keep in mind that these are my recommendations and they do not necessarily align with VMware’s recommendations or requirements. Sizing Sizing is one of the most difficult parts in my opinion.

Hotfix needed to move R2 differencing disk to Windows Server 2008

A virtualization MVP recently bought this to my attention: In Windows Server 2008 R2 there was a minor change to the format of differencing virtual hard disks.  As a result you will need to apply an update to Windows Server 2008 if you want to move differencing disks from Windows Server 2008 R2 to Windows Server 2008. You can download this update from here: http://support.microsoft.com/kb/971677 Note that this applies to Windows Server 2008 and Windows Server 2008 SP2 (not to Windows Server 2008 R2).  If you do...

The Time to Redefine Client Application Licensing is Now

There’s been plenty of fanfare surrounding the release of Citrix XenDesktop 4.0 this week. I plan to blog about the XenDesktop 4.0 technical features after I’ve spent some quality time with them in my lab over the next couple of weeks. However, I’d like to contribute to the XenDesktop 4 conversation by talking about its impact on client software licensing. It’s no question that user expectations for how they should access corporate resources are changing. Sometimes I need to quickly grab or view a doc from my iPhone. Other times I... [Lire la suite]
