Nope. I have decided not to touch blade servers until the technology matures a bit. The bladecetner in particular is not appealing with it's laptop hard drives. Yes you can add a SCSI module to a server, but then you start defeating the purpose by taking away a slot for another server. I suppose you could hook it up to a SAN and boot off that SAN, but all in all, the technology is not there.
As far as your question goes, I would consult the documentation.
It is what it is!!
