vSphere with Heterogeneous CPU's

[Nicodemus555]

Can anyone direct me to documentation on how vSphere or ESX 4 handles Heterogeneous CPU processors... i.e., AMD + Intel mixed in the same envirnonment..?

Appreciate it.. -

Mixing AMD and Intel is not an option.... (if you need vMotion, DRS)

Enabling EVC helps out mixing CPUs within in the same family.. Check http://kb.vmware.com/kb/1003212

Depending on how many hosts with each make processor you have, you could set up clusters containing each type. Such as Cluster A with all Intel processors, and Cluster B with all AMD processors. That way you can have HA/DRS/etc functioning in each cluster (internally, just not to the other cluster)...

Personally, I'd dump the AMD hosts and get all Intel powered units to replace them.

In general that's not a problem. HA doesn't care about CPUs, so HA cluster will run perfectly on heterogeneous CPUs. Only possible issue here if you have some CPU-sensitive application in VM.

But as already said, AMD/Intel mix is not supported for VMotion, DRS and FT. You have to create different clusters with AMD or Intel CPUs only.
