Processors and guest operating systems that support VMware Fault Tolerance

Details

VMware Fault Tolerance (FT) requires specific processors (CPU) and guest operating systems.

Solution

Processors 

VMware collaborated with AMD and Intel in providing an efficient VMware FT capability on modern x86 processors. The collaboration required changes in both the performance counter architecture and virtualization hardware assists of both Intel and AMD. These changes could only be included in recent processors from both vendors: 3rd-Generation AMD Opteron based on the AMD Barcelona, Budapest and Shanghai processor families; and Intel Xeon processors based on the Penryn and Nehalem microarchitectures and their successors.

Download the VMware SiteSurvey (http://www.vmware.com/download/shared_utilities.html ) utility to check if your configuration can run VMware FT.  

For VMware FT to be supported, the servers that host the virtual machines must each use a supported processor from the same category as documented below:
Intel Xeon based on 45nm Core 2 Microarchitecture Category:
  • 3100 Series
  • 3300 Series
  • 5200 Series (DP)
  • 5400 Series
  • 7400 Series

Intel Xeon based on Core i7 Microarchitecture Category:

  • 3400 Series (Lynnfield)*
  • 3500 Series
  • 5500 Series
AMD 3rd Generation Opteron Category:
  • 1300 and 1400 Series
  • 2300 and 2400 Series (DP)
  • 8300 and 8400 Series (MP)

* requires VMware vSphere 4.0 Update 1 or greater

Guest Operating Systems
 
The following table displays guest operating system support for VMware FT. For specific guest operating system version information, see the Guest Operating System Installation Guide at http://www.vmware.com/pdf/GuestOS_guide.pdf.
 
The following values appear in the table:
  • Yes - Virtual machine can be FT-enabled while powered on.
  • Yes/Off - Virtual machine must be powered off before FT is enabled
  • No - Not supported by VMware FT.

Note: System vendors are certifying that their systems work with FT. You can find details on the FT-certified systems at http://www.vmware.com/resources/compatibility. More systems are being certified all the time, so check back if your platform is not currently listed.
You can also check processor, operating system, and virtual machine configuration compliance with FT by downloading and running the VMware SiteSurvey utility from http://www.vmware.com/download/shared_utilities.html. It highlights compliance issues and describes how to correct them.
