we got a vmware cluster with 16 physical servers they are connected to virtual infrastructure with VMotion / DRS. All data is stored on a SAN.
Usually we use Debian Linux servers but we are about to migrate our windows servers to that cluster instead of buying new hardware for them.
My question is, is there a way to minimize the licensing costs for windows. I know there is the windows datacenter edition and it allows us to run unlimited servers on a single server (licensed per CPU) but with 16 * 4 CPUs (and more to come) we would feel "a little bit overlicensed" to deploy our 12 (!!) windows servers (win 2k3 standard using 1 cpu) in that cluster.
So is there a way to tell vmware vmotion to move those windows servers just around let's say 3 servers licensed with 4 cpu datacenter editions? Or how should we proceed here?
