A Rack of One's Own

the beast at this point will still consume less than a kilowatt at full juice. i have no idea why the chassis ships with 1620W supplies, unless perhaps SAS drives consume ridiculous amounts of power? which, speaking of storage...

the original point of this hoss was to get hard drives out of my workstation, and it was time they went. sixteen 18TB exosen were removed from use, and joined eight more virgin 18TBs. the result is 3x octadrive raid6zs each boasting 144 total, 108 usable, for a total of 324TB accessible at any given time. at full jam, this is about another 200W of mixed 5V+12V (see "[[Schwarzger%C3%A4t_III#The_drive_problem|The Drive Problem]]" for more details), and generates the system's only noise (though that'll change once the K80s arrive). my office is now several degrees cooler, a happy change i thoroughly welcome.

so, that's the story of my [[Strangelet|living room supercomputer]]. 96 watercooled Xeon cores, 9984 CUDA cores, 2.3TiB DDR3, 2.8TB NVMe SSD, 324TB SATA3 rust, 280Gb/s networking on a mix of fiber and copper, and 4x 80PLUS Platinum 1280W PSUs, drawing a maximum of ~1200W. the entire rack (machine, lighting, cooling, and all externals) consumes under 600W most of the time:

do you think this is some kind of game, son?
