Oooh - good question. The SGI rack-back water cooled system is excellent, however the racks are SGI-size. You would be able to get multiple generations of SGI kit in the same racks - their IRU units are the same size, so you could go IA64/ICE/Ultraviolet. But that's not really multi-vendor equipment! On the cooling side, I heard that Imperial College went for a CO2 based cooling system - similar rack-back cooling radiators, but you pump CO2 through them. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
