VMware vSphere 4.1 Update 2 Released

October 27th, 2011 by jason Leave a reply »

As I sit here working on an SRM lab, VUM just sent an email to me reporting 28 new patches for ESX(i) 4.1 including the release of 4.1 Update 2.

What’s New

The VMware vCenter Server 4.1 Update 2 release offers the following improvements:

  • Support for new processors: vCenter Server 4.1 Update 2 supports hosts with processors on AMD Opteron 6200 series (Interlagos) and AMD Opteron 4200 series (Valencia).
    Note: For the AMD Opteron 6200 and 4200 series (Family 15h) processors, vCenter Server 4.1 Update 2 treats each core within a compute unit as an independent core, except while applying licenses. For the purpose of licensing, vCenter Server treats each compute unit as a core. For example, although a processor with 8 compute units can provide the processor equivalent of 16 cores on vCenter Server 4.1 Update 2, only 8 cores will be counted towards license usage calculation.
  • Additional vCenter Server Database Support: vCenter Server now supports the following databases.
    • Microsoft SQL Server 2008 Express (x32 and x64)
    • Microsoft SQL Server 2008 R2 Express (x32 and x64)
  • Resolved Issues: This release delivers a number of bug fixes that have been documented in the Resolved Issues section.

  1. There are some really noteworthy bug fixes in Update 2 that I have listed on my blog at http://v-front.blogspot.com/2011/10/vsphere-41-update-2-released-whats-in.html.
    The most important one is a resolved vMotion issue that caused large-memory-VMs to lose pings while being migrated.

  3. Thanks for the post on the vSphere 4.1 update. Is vSphere 4 going to hang around longer than expected? I feel like it will be sort of like XP, people are still using XP and swear by it.
