Explanation

HPE SimpliVity is a hyperconverged infrastructure solution that combines compute, storage, networking, and data services in a single appliance. HPE SimpliVity clusters are groups of HPE SimpliVity nodes that share the same federation and data center. HPE SimpliVity clusters can be expanded by adding new nodes to increase the capacity and performance of the cluster. However, adding new nodes with newer generation Intel CPUs to an existing HPE SimpliVity cluster may cause compatibility issues for vMotion, the VMware technology that enables live migration of virtual machines between hosts. vMotion requires that the source and destination hosts have compatible CPUs, meaning that they support the same set of CPU features. If the new nodes have different or additional CPU features than the existing nodes, vMotion may fail or To facilitate adding the new hosts to the cluster, one possible solution is to enable Enhanced vMotion Compatibility (EVC) on the cluster. EVC is a feature of VMware vSphere that ensures vMotion compatibility for the hosts in a cluster that are running different CPU generations. EVC masks the CPU features that are not common among all hosts in the cluster, so that all hosts present the same CPU feature set to the virtual machines. This way, vMotion can be performed without CPU compatibility errors.
