I agree keep the infrastructure stuff physically separate from the
student stuff. That said, say a 4 node cluster for infrastructure stuff
running VMs on each node in a scenario where the other nodes can take
over VMs from a failed node. Have them run to Fiber storage or some kind
of SAN and you should be all set.

For student stuff you can run a separate cluster using VMs for different
courses, maybe Vmware, maybe Xen whichever works for you.

CentOS should be able to handle all that very well, it is after all RHEL
and has been tuned for heavy duty workloads.
