EVC Enable on cluster

[sreng channy]

Dear Expert team, 
Hope you good and well. 
I would like to be asked about the EVC enable on the cluster. 

I have HPE cluster is running on hardware below:

• Intel(R) Xeon(R) Silver 4214R CPU @ 2.40GHz | Hardware model: ProLiant DL380 Gen10
• Intel(R) Xeon(R) Gold 6226 CPU @ 2.70GHz    | Hardware Model: ProLiant DL380 Gen10

Cluster UCS01

• Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz | Hardware Model: UCSC-C240-M5S
• Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz | Hardware Model: UCSC-C240-M5S

Cluster UCS02

• Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz | UCSC-C240-M5S
  
• Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz | UCSC-C240-M5S

Cluster Lenovo

• Intel(R) Xeon(R) Gold 5317 CPU @ 3.00GHz | ThinkSystem SR650 V2
  
• Intel(R) Xeon(R) Gold 5317 CPU @ 3.00GHz | ThinkSystem SR650 V2 MB

Which the EVC model should I choice?

EVC needs to be set to the CPU with the lowest feature set, which - assuming you want to live migrate VMs between all of your clusters - would be the one for the E5-2630 v4 CPUs, i.e. "Broadwell".

Please note that setting an EVC mode requires that a.) the host's CPU supports that mode, and b.) no VM is currently running with a higher mode (with CPU features that are not provided by the EVC mode).
