I'm curious about buying a cMP and letting it double as my file server and a workstation. Is it possible to run the RAID array in a VM? Is there a way to have VT-d extensions with the 5,1 Mac Pro (or 4,1)? Without VT-d extensions, my understanding is I can't have RAID in a VM so using the 4,1 or 5,1 Mac Pro as both a file server and workstation is not possible. Am I correct? Thanks.
