With the launch of VMware vSphere this week there are some new features to play with. One of the most interesting features, I think, is VMware FT (Fault Tolerance). Implementation of this features introduces some new caveats, in the case of FT you can not use all CPU’s and you can only apply FT on virtual machines with 1 vCPU. 1vCPU limits the implementations but is very easy to check in contrast to finding more compatible CPUs.

To check which CPUs are compatibel Gabrie van Zanten from Gabes Virtual World published a great article with a matrix of compatibel and incompatibel CPUs.

You can check the list and read the article here.
