I had a quick question on a cluster. Since this is a production cluster I wanted to double check for clarification. Currently have a 3 node 2012 R2 hyper-v cluster. The servers are all Dell R610's with Dual Intel E5540 processors. I wanting to introduce a 4th node into the cluster only I was thinking of doing an R610 with Dual X5570 processors for a little more power. My questions is, since these are all R610's and the processors are all from the same generation/release date, would I still have to go through and mark the checkbox on all the VM's for the "migrate to a physical computer with a different processor version"? Or since they are the sam Generation would everything work as normal. Any other pitfalls I'm missing?
