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. -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.
