Dear Firens;

I have a Cluster with two HP DL380 G6 (Xeon X5560) servers and i want to add another server HP DL380 G7 with these Types of CPUs:

I want to know that, which of these CPUs can use with EVC Mode in my Cluster?

[Dave_Mishchenko]

If you're mixing those two CPUs in an EVC cluster you'll need to set the EVC mode to Intel Nehalem.  See the KB article here for more info - http://kb.vmware.com/kb/1003212.

vCenter can also help to find the right baseline.

Just try to enable EVC on your cluster of old CPU: the only one that can be enable (without power-off the VM) is the right one
