I was at Spiceworld 2012 Austin on the 11th and 12th of October and got some clarity on the issue of vSphere 5.1 Enhanced vMotion in Essentials Plus (which doesn’t have Storage vMotion). Mike Fegan, a VMware SE, explained that on Essentials Plus, we have the option to do a standard vMotion, if we are using shared storage, or a run state plus Storage vMotion, but not a pure Storage vMotion. He later re-stated that on Spiceworks. Thanks again, Mike.
