What is VMware Enhanced vMotion Compatibility (EVC) [vladan.fr]
I know many of you knows what that is, but this post is targeting people who do not or know a little bit, but they’re not sure if what they know is enough. If you’re experienced VMware admin you’ll won’t find probably anything you don’t already know. VMware Enhanced vMotion Compatibility (EVC) is a vSphere cluster feature which allows virtual machines (VMs) to use vMotion between hosts with different processors. (CPUs). The way that EVC works is basically masking the advanced capabilities of the newer CPUs in order to have the same level fo instructions across the whole VMware cluster.
