Rack power density has been balooning the last few years. Typical power consumption was ~5kw per 42u rack for like a decade. Now we are nearing 20kw average. Compute oriented systems for AI workloads and whatnot pack 60kw+ per rack. A lot of older datacenters have to run half full racks because their central cooling system can't deal with the heat of full ones anymore.

We’re going to be reaching the limit of what traditional cooling methods like CRAC units are capable of with those densities. I hope to see more liquid cooling applications or other solutions like rear doors that aren’t as prevalent as traditional CRACs.

I used to for for a company that uses self enclosed cabinets to avoid the use of floor AC units and isolate intense workloads. Scalematrix / DDC. Super interesting compared to raised floor. From what I can tell it's still kinda expensive, but the idea is promising.

Oh nice. I’m familiar with Scalematrix. Raised floors aren’t as prevalent as they used to be and honestly it’s for the better.

Oh cool! Yeah, having now worked in a switch facility for another company, as well as raised floor sites, concrete slab, and cooling similar to these is the way forward.

Liquid door also comes to mind.
