I have 2 type of server  with different type of cpu as below :

HP DL380P g8 (Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz)

HP DL380P G9 Intel(R) Xeon(R) CPU E5-2698 v3 @ 2.30GHz

I want to ensure is that possible reside these different type of server in one cluster with EVC mode ? if YES, which type of EVC mode had to select ?
