It would not be unlikely for the power of this workstation to be comparable to more than the processing capabilities of a fully populated Proliant DL580 quad CPU Xeon server.

Good point. I don't particularly doubt that it is there, just don't want to count unhatched chickens, you know? HP used to sell Proliants with the built in virtualization disabled via BIOS. Not that IBM would pull that, but without knowing that the feature is there for sure, it's something to look into.
