AIUI the 15kW power limit per rack is going to be a constraint down the line, since it appears that newer AMD hyperscale hardware will be built for a higher level of power density, one that pretty much relies on the use of liquid cooling. To some extent, that was the point of those new Zen 4c and 5c core designs. Even with Oxide's use of rack-scale fans, I'm not sure that they'll be able to shed the amount of heat that these newer chips are going to be designed for. Of course there are very similar concerns if you want to do HPC with CPU+GPU compute, too.
- actionfromafar 3y agoI wonder how much such concerns will matter in a real-life scenario. They mentioned they can use power-save features of AMD CPUs better than any other hardware vendor. Interesting offering from Oxide nevertheless. They seem to take a broad system view. It's like a rack is like a very large PC, not a bunch of PCs in a rack. Makes me think of IBM a bit.

For something like HPC, many systems are getting into water cooling nowadays: either air-cooled servers with a rear-door radiator (60kW), or with water-cooling right to the servers. * https://www.lenovo.com/us/en/servers-storage/neptune/ https://www.lenovo.com/us/en/servers-storage/neptune/ * https://www.supermicro.com/en/solutions/liquid-cooling https://www.supermicro.com/en/solutions/liquid-cooling
