Was looking through my office window at the data closet and (due to angle, objects, field of view) could only see one server light cluster out of the 6 racks full. And thought it would be nice to scale everything down to 2U. Then day-dreamed about a future where a warehouse data center was reduced to a single hypercube sitting alone in the vast darkness.
I had this problem with Equinix! They limited our company to like 10kva per rack, and we were installing nvidia dgx servers. Depending on the model we could fit only one or two lol.
