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.
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.
