Hi Richardson,
Thanks for the reply.I ran the compatibility report and I found that Intel Xeon Processor E5-2680 v4 which is (Broadwell) does not show up in the compatibility list for Intel Xeon Processor E5640 (Westmere EP)
So if I understand correctly you are advising to make possible vMotion between these two models of CPU, configure your cluster with EVC L3 (Westmere)??
Is that correct?
