VMWare ESX vLockstep support

I am interested in ESX Advanced for its fault tolerance feature.

I know this requires that all CPUs on the servers support the vLockstep Feature found on some AMD and Intel processors.  

My question is do the servers have to have the same brand CPU's.  Can I have 1 server with Intel Processors and 1 server with AMD processors and VMWare fault tolerance on them?

    Assisted Solution

    You can use CPU masking to enable/disable features presented to the guest to allow for using different CPU's, but this is only recommended when you have the same brand of CPU.

    I wouldn't recommend that you try mixing AMD and INTEL cpu's for HA.

    For normal HA is perfectly fine to mix but you cant mix them for FT and FT esx hosts must have CPU from the same category
