Yes, well it isn't that dense either. As I have written, it's 32 CPUs (16x 2 CPUs). 1 TB of RAM per CPU is not that huge a deal, it's perhaps 16x 64 GB (Milan uses 8 channels, 2 DIMMs per channel is reasonable), if you consider that is 16 GB of RAM per core. In HPC, you would probably shrink it to 1/4 of the volume (half width, 1 U dual socket server). Oxide probably focuses on optimal thermal efficiency since their limit isn't the space so much as the power density/ max. power per rack in existing DCs, which they are already pushing hard. (Of course they have lower power options too but they probably will not use 2048 cores.)
- spamizbad 5y agoThe problem with pushing higher compute density is you're running into the limits of what most DCs can provide in terms of power and cooling for a single rack. Usually it's specialized HPC facilities or hyperscalers pushing the power and cooling to handle stuff like that. Those people aren't likely Oxide's customers - they've already got their own hardware solutions.
- Tuna-Fish 5y agoThere are 32 half-width compute blades there, so probably single socket servers with 64 cores each.
- kaliszad 5y agoIt does look like it. Perhaps it is easier for maintenance, if you don't want to start with a full rack. The upgrade granularity is higher.
