HyperFlex supports Intel v3 and Intel v4 CPUs on the same fabric interconnect. Enable VMware Enhanced vMotion Compatibility (EVC) to migrate virtual machines between Intel v3 and Intel v4 CPUs. After EVC is enabled, all hosts in the HyperFlex cluster are configured to give them a baseline with features of the lower model of CPU. Identical CPU features are exposed to virtual machines regardless of which host they are running on, so virtual machines can be migrated between hosts in a HyperFlex cluster. This ensures CPU compatibility for vMotion even if the hosts have different underlying hardware.
