So what’s that good for? Like eight of Nvidia’s NVL-72s?
As GPUs and AI accelerators push beyond one kilowatt of power consumption, many systems builders are turning to liquid cooling to manage the heat. However, these systems still rely on complex networks of plumbing, manifolds, and coolant distribution units to make it all work.
While a megawatt of capacity might seem like an obscene amount of cooling, when it comes to cooling modern AI systems, it doesn't go as far as you might think. Next-gen systems from companies like Nvidia will cram somewhere between 5.4kW and 5.7kW of compute in a single RU server and upwards of 120kW in a single rack.
Rent-a-GPU outfits like CoreWeave and Lambda are deploying tens of thousands of accelerators. Even with a megawatt cooling capacity, they will still need a lot of CDUs if they want to take advantage of Nvidia's most compute dense configurations.
