VMware KB: Enhanced VMotion Compatibility (EVC) processor support

VMware KB: Enhanced VMotion Compatibility (EVC) processor support

Documento da VMware, explicando a compatilbilidade dos processadores xeon 5500 com a familia de processadores 5600 através do vmotion.

Enhanced VMotion Compatibility (EVC) simplifies VMotion compatibility issues across CPU generations. EVC automatically configures server CPUs with Intel FlexMigration or AMD-V Extended Migration technologies to be compatible with older servers.

After EVC is enabled for a cluster in the VirtualCenter inventory, all hosts in that cluster are configured to present identical CPU features and ensure CPU compatibility for VMotion. The features presented by each host are determined by selecting a predefined EVC baseline. VirtualCenter does not permit the addition of hosts that cannot be automatically configured to be compatible with the EVC baseline.
