We have just upgraded to vSphere 6 Essentials Plus so we can take advantage of vMotion. We are building an almost exact replica of our existing Dell PowerEdge T420 server, so that we can have high availability for our VMs, moving them from one physical server to the other, as needed. In looking through the DRS cluster documentation, it says that processors "must come from the same vendor class (Intel versus AMD) and the same processor family to be compatible for migration with vMotion. (vSphere 5.5 Documentation Center)"
Our current server has an Intel Xeon E5-2440 v2 processor (8 cores, 20 MB cache, 1.9 GHz). The vendor we are purchasing our new server build from has the same processor model number (Intel Xeon E5-2440), but with 6 cores, 15 MB cache, 2.4 GHz. They would have to special order the exact same processor we currently have. Will we run into any issues if the rest of the hardware is the same, but the processors are slightly different? Same vendor, same family, even same model number - just with less cores, less cache, more GHz. Is there anything I should consider before moving forward?
Thanks!
