I was confused for a long time trying to reconcile the claim of "912 computers per rack" with what I observed in the video: 18 servers per cartridge, 16 cartridges per case, so 288 servers per case. I finally realized they must have meant cores: so 4 cores x 18 servers x 16 cartridges = 912 cores per case is probably how I would have put it.

Ballparking the size of the case based on the comparison of a single server to a business card, it looks like they're using roughly a 7U case. Anybody know more about the specs of a case-load of servers? I'd love to know what the power consumption is. If you could put 6 of those cases in a cabinet, that would be some pretty incredible compute density.

I hope they consider selling the system externally. At first blush at least it seems like it would be an ideal setup for hosting colocated trading applications.



Each server has 4 cores. So a rack contains actually 3648 cores, not 912!


You're assuming that when they say "912 computers per rack" they mean 912 4-core servers per rack. It's a reasonable assumption, that's how I interpreted that statement when I read it the first time. Nonetheless, I'm quite sure that that interpretation is incorrect.

If you watch the video carefully, you'll notice that their rack/case contains 16 cartridges, and each cartridge has 18 servers on it. That indicates they have 288 servers per rack. 288x4=912, so I believe that when they said 912 computers per rack, they actually meant 912 cores per rack.
