How did you arrive at the decision of not putting the GPU machines in the colo? Were the power costs going to be too high? Or do you just expect to need more physical access to the GPU machines vs the storage ones?
- g413n 1y agoWhen I was working at sfcompute prior to this we saw multiple datacenters literally catch on fire bc the industry was not experienced with the power density of h100s. Our training chips just aren't a standard package in the way JBODs are.
- Symbiote 1y agoIsn't the easy option to spread the computers out, i.e. not fill the rack, but only half of it? A GPU cluster next to my servers has done this, presumably they couldn't have 64A in one rack so they've got 32A in two. (230V 3phase.)
- pixl97 1y agoRackspace is typically at a premium at most data centers.
- Symbiote 1y agoI'm more surprised that a data centre will apparently provide more power to a rack than is safe to use.
- toast0 1y agoMy info may be dated, but power density has gone up a ton over time. I'd expect a lot of datacenters to have plenty of space, but not much power. You can only retrofit so much additional power distribution and cooling into a building designed for much less power density.
- lemonlearnings 1y agoAdding the compute story would be interesting as a follow up. Where is that done? How many GPUs do you need to crunching all that data. Etc. Very interesting and refreshing read though. Feels like what Silicon Valley is more about than just the usual: tf apply then smile and dial.
