That is a beast of a fan at the bottom.

It's an AlphaServer GS80, GS160 or GS320 (part for the last 2), think it's probably a GS80 (8 processors), but like the Origins the lines can blur. I think the blower is even bigger than the one used on SGI Predator racks, but DEC has always used pretty big fans on the large boxes.

The Predator rack has a fan tray, similar to an O2K, with 4 Nidec Beta V fans in it. It's the Onyx1, and the gfx module of an Onyx2 rack that have the really large blowers.

Biggest blower I've seen was in early Alpha server.

It was jokingly called the Alpha with an AMD! (Air Moving Device)

It's a weird rack in the auction, doesn't look at all like the originals.

Interesting, the IRIS x000 series has the annular blower. I wonder why they waffle between that and the fan tray.

VAX-6000 is supposed to be just about the ultimate - 3-phase blower motor on a very large fan.

Couldn't say. Meanwhile, I found back a picture I took when I took the 4D/380 apart for cleaning and replaced the power cable between the PSU and the 'blinkenlights' panel. It had shorted at some point in history and suffered the full 250A @ 5V wrath of the PSU, which had left molten plastic and drops of copper everywhere

The fan tray is operated from the -12V rail of the PSU, and I think under most circumstances that's the only significant load on that rail. The blinkenlight panel is always like this until it's initialized by the PROM. Needless to say, that wasn't going to happen here



Oh, I believe the SunFire V880 uses compatible fans. Probably a better chance to find one of those than a 'genuine SGI predator rack' fan.

Anyway, if you can house and feed it the Alpha GS80+ machines are kind of slick. They're similar to an Origin2000 in that they're expandable NUMAboxes.

This seems to be the System Logic Cabinet - other half of a larger GS160 or GS320 system.
It's pretty pointless if you don't have an existing GS160 that you want to expand or have a System Power Cabinet in place already - and CABLES. All in all it's worthless on its own, since it relies on power bricks much like the Origin3000 series and probably PCI-expanders for base I/O.

I think this link might clear things up a little: http://h18000.www1.hp.com/products/quic ... 23_na.html
