This is what is inside the slots on the rack. Very efficient! We’re looking at an open case containing drives and circuit boards with very shiny copper pipes for liquid cooling. It’s sitting on a little table next to an orange bollard with “do not cross” tape hanging off it.

More pretty green lights! A couple of rack units with lots of happy little drives, churning away on goodness knows what.

Newer units! This is NVIDIA gear, I have been told. And very expensive because people want to use this type of gear to get ChatGPT to do whatever it is people do on ChatGPT. But not these unit. No, they are here to do data analysis to project the impacts of climate change, develop drought resistant crops, and understand viruses at the atomic level.
