"Each immersion tank can contain 16 Bricks. A Brick consists of a backplane board, 32 PEZY-SC2 modules, 4 Intel Xeon D host processors, and 4 InfiniBand EDR cards. Modules inside a Brick are connected by hierarchical PCI Express fabric switches, and the Bricks are interconnected by InfiniBand."
I remember some offhand remarks on that. Apparently the rooms for these systems had cheap ladles hanged somewhere and engineers would have fun scooping out water puddles collecting on top of enclosures full of fluorinert coolants. That's tanks full of PFAS in layman's terms...
