The photo of that unit is entertaining. Whoever buys it will need to setup 3x 30A 220v outlets. That's going to make some licensed electrician very happy.
At the old small office I would just pop some breakers out and replace them with 2 pole 30 amp ones. When it was at the hackerspace there was some sort of fused cut off switch box on the wall, so I terminated a twistlock 30A and ran from there over to a subpanel that had the 3 twistlocks for the Cray cabinets. I used A-B B-C C-A phases, so 208V each. I still have the subpanel and also a SquareD Powerlogic monitor w/ CTs and stuff that are mounted to the board that was with the system (might be visible in the picture.) I used a rubber core cable to run between the two -- which I originally had picked up to temporary run a 6 watt argon laser system with from time to time.
I originally had 4 of the J932SE systems, they were all HIPPI'ed together to form one system when used for power engineering for nuclear subs or something (Bechtel.) I dunno, it was all secret and they destroyed all of the hard drives and such from the system.
I never really thought the power was that crazy, I work in datacenters and these days there are single racks using twice what the Cray takes!
I worked with a Cray for a while of about the same vintage (pre-SGI Cray running UNICOS and using an Sun SPARC Classic as a helper). It was a large telco (MCI) and used for fraud-detection on calling cards. It was a UNICOS-based system in a private Colorado Springs datacenter about two blocks from some sort of manufacturing site for Cray (the building is on Rockrimmon in Colorado Springs - the former home of the late Seymour Cray). I thought the whole rig was interesting, but it was barely a few weeks before the whole company went through a near-death experience (two words: Bernie Ebbers) and I walked across the street to another company and scored a new gig (it was the late 90's, you could do that sort of thing then). I never got a chance to get really proficient with the hardware or with UNICOS. It was my singular regret with that gig, though.
Very cool! NASA LaRC had a J916 system used by some scientists for something, other than that I don't know of any others. I was a SGI guy at the same place, had some nice boxes.
