Physical to Virtual Planning
Im about to start planning my p2v of servers, but Im not entirely sure what specs to give the new VMs. Im not able to do an actual P2V using SCVMM as I will be moving services off old 2003 servers to new 2008R2 machines, so most will be rebuilds.
But at the moment our current servers are vastly overspecced (24gb ram on a file server, 16gb ram for a box running oliver, etc). So obviously Im not going to be needing to provision anything like that for the virtual servers, but the question is, what would be a good spec.
Is there an agent or something I can run on the servers over a month to log Memory and CPU averages to give me a rough idea of what they are actually using?
And also with regards to virtual processors, each of our servers has 24 cores, how many virtual processors should each VM get?
