The white tank is a make-up tank in the Cooling Distribution Unit (CDU). Replacing blades may remove some water from the system. If the CDU needs to add some coolant, it pulls it from this tank.

The Cray racks are water cooled as far as I know. The can is a helium tank, which the sysadmins use to make their voices sounds like chipmunks. This is exactly what you need to do when you are dealing with nuclear weapons.

Are the blues and reds at the back of the units tubes for the liquid cooling or just cables? Also, in the last picture, what is the white gas can like container at the bottom of the last rack?

Hmmmm … bring on the petaflopping cephalopods (nodules of 16 MI300A or GH100 units, with uber-fast networking tentacles), scatter them about in a thousand remote locations, and heed the composable rise of solar-powered ExaCthulhu!

I agree–it is extreme. But that is supposed to be HPC’s job.

OK, now you went and hurt my head there….
