EVC on ESXi 5.5 Cluster of both Intel Xeon E5-2630 v3 (Haswell) and Intel Xeon E5-2630 v4 (Broadwell)

[KobiLazar]

I have an existing Cluster of ESXi 5.5 Hosts (build 2068190), running on Cisco UCS blades running Intel Xeon E5-2630 v3 (codename Haswell).

I have purchased additional Cisco UCS blades and they are running on Intel Xeon E5-2630 v4 (codename Broadwell).

Do I need to enable EVC on my Cluster ?

Under the “enable EVC for Intel Hosts” I see the following options:

Intel “Merom” generation

Intel “Penryn” generation

Intel “Nehalem” generation

Intel “Westmere” generation

Intel “Sandy Bridge” generation

I don’t see “Ivy Bridge” nor “Haswell” …

What should I do ?

You should enable EVC to be able to migrate VM's between the different  types of hosts.

The following KB article lists the maximum supported EVC level per ESXi version, Enhanced vMotion Compatibility (EVC) processor support (1003212) | VMware KB

For ESXi 5.5, this is Intel Ivy Bridge. This EVC level can only be set from the vSphere Web Client as it is not visible with the vSphere C# Client.
