I'm having some trouble to figure out vMotion (without EVC) is possible between hosts with X5600 and E7-2800 CPU's. Both CPU's are from the Westmere Generation. I've read the vMotion CPU compatibility guide and both CPU's are in group E. They have the same CPU features according to Intel spec sheets:
Intel® Xeon® Processor 5600 Series
Intel® Xeon® Processor E7-2800 Product Family
I'm thinking that vMotion is possible without EVC because they are from the same Westmere generation (EP and EX). Our supplier however tells me that i need the same CPU series for vMotion, in this case a machine with an E7 CPU to replace the X5600 host.
So is my supplier right or wrong? Do i need to buy a second server with an E7 CPU for vMotion compatibility or can i keep the servers with X5600 CPU's buzzing?
