I have a Hyper-V R2 cluster with 2 nodes and we need to add a third. I know it is best to have the same hardware. Our current 2 servers are identical but the new one will likely be a newer model. How identical does the hardware need to be? Are there specifics that must be identical and if so how close do they need to be, processors, NICs, etc? Thanks.

Mostly the requirements are around processors. Definitely same vendor but also there are some specific features should match across hosts. To check the specific features you can use this tool:

Ok, to be more specific we currently have 2 HP Proliant DL580 G5s with 4 quad core processors that are identical. The new server would be a HP Proliant DL380 G7 with 2, 6 core processors. What problems might occur? Is this a good idea? Would 3 nodes in a cluster be a lot more challenging to manage particularly with failovers occuring to multiple servers?
The other option we are considering is to buy 2 new DL380 G7s and create a new cluster. Is this option better than going with a third node in the cluster particularly if the hardware is different?
