I mentioned ESX 3.5 Update 5 only yesterday in my post about VMtools on Windows 2008 R2. Little did I know that 16 hours later I’d be writing about it again to say that it had been released!

The update can be downloaded from VMware’s website as usual. Shamelessly copied from the release notes, here’s what you can expect to have changed:

Enablement of Intel Xeon Processor 3400 Series – Support for the Intel Xeon processor 3400 series has been added. Support includes Enhanced VMotion capabilities. For additional information on previous processor families supported by Enhanced VMotion, see Enhanced VMotion Compatibility (EVC) processor support (KB 1003212).

Driver Update for Broadcom bnx2 Network Controller – The driver for bnx2 controllers has been upgraded to version 1.6.9. This driver supports bootcode upgrade on bnx2 chipsets and requires bmapilnx and lnxfwnx2 tools upgrade from Broadcom. This driver also adds support for Network Controller – Sideband Interface (NC-SI) for SOL (serial over LAN) applicable to Broadcom NetXtreme 5709 and 5716 chipsets.

Driver Update for LSI SCSI and SAS Controllers – The driver for LSI SCSI and SAS controllers is updated to version 2.06.74. This version of the driver is required to provide a better support for shared SAS environments.

Newly Supported Guest Operating Systems – Support for the following guest operating systems has been added specifically for this release:

For more complete information about supported guests included in this release, see the VMware Compatibility Guide: http://www.vmware.com/resources/compatibility/search.php?deviceCategory=software.

  • Windows 7 Enterprise (32-bit and 64-bit)
  • Windows 7 Ultimate (32-bit and 64-bit)
  • Windows 7 Professional (32-bit and 64-bit)
  • Windows 7 Home Premium (32-bit and 64-bit)
  • Windows 2008 R2 Standard Edition (64-bit)
  • Windows 2008 R2 Enterprise Edition (64-bit)
  • Windows 2008 R2 Datacenter Edition (64-bit)
  • Windows 2008 R2 Web Server (64-bit)
  • Ubuntu Desktop 9.04 (32-bit and 64-bit)
  • Ubuntu Server 9.04 (32-bit and 64-bit)

Naturally you’ll need to upgrade vCenter to Update 5 to gain some of these benefits. The release notes for that mention only one significant enhancement:

Support for High Consolidation in VMware HA Clusters – VirtualCenter 2.5 Update 5 includes significant performance and scalability improvements to VMware HA. Use VirtualCenter 2.5 Update 5 for environments with more than 35 virtual machines per host in an HA cluster.
For information on the ESX Server host settings required for this scalability improvement, see ESX Server host settings required for environments with up to 80 virtual machines per host in an HA Cluster (KB 1012002).

I think that there is a good chance that Update 5 may be the last major update that the 3.5 line of products receives. Or at least it will be for some time. I’ll have some upgrades to do as a result of this release but I’m pushing for upgrades to vSphere like crazy. You know it makes sense.
