Only the Onyx series has graphics :-) Most of ours at NASA were headless 
with nothing but a serial console, and lots of CPUs. They crunched 
satellite data all day. 96 Processors on Origin 3800, Normally 32 IIRC on 
the Challenge XLs.

I didn't know there was a 3 phase option. Was it an Onyx2 or Onyx?

My Cray uses 5 of the Sun E10000 style Pioneer Magnetics 5000 watt 48vdc 
PSUs, and even it was single phase (although I had it sitting across 3 
phases just to get the power to it over a 30 amp cable.)

Very cool!

Yes, crammed full. The video cards are stuffed!
