The website is pretty “technical content free” – it’s essentially a sell-sheet, without a summary of specifications. And, I couldn’t find anywhere that says how it works.

It's really cool (literally and figuratively).

We are most limited by datacenter floor space. We can manage to bring in more power (up to 40 MW for Frontier) and install more cooling towers (ditto), but we cannot simply add datacenter space. We have asked to build new building and the answer has been consistently "No." Summit is mostly water cooled. Each node has cold plates on the CPUs and GPUs. Fans are needed to cool the memory and power supplies and is captured by rear-door heart exchangers. It occupies roughly 5,600 ft^2. With 200 PF of performance and 14 MW of power, that is 36 TF/ft^2 and 2.5 kW/ft^2. I am wondering what the comparable performance and power is per square foot for the densest, deployed (not theoretical) immersion cooled systems. Any ideas? To make the exercise even more fun, what is the weight per square foot for immersion systems? Our data centers have a limit of 250 or 500 pounds per square foot. I expect immersion systems to need higher loadings than that.
