Immersion Cooling Drives Server Power Densities To Insane New Heights (datacenterfrontier.com)
1sockchuck writes: By immersing IT equipment in liquid coolant, a new data center is reaching extreme power densities of 250 kW per enclosure. At 40 megawatts, the data center is also taking immersion cooling to an entirely new scale, building on a much smaller proof-of-concept from a Hong Kong skyscraper. The facility is being built by Bitcoin specialist BitFury and reflects how the harsh economics of industrial mining have prompted cryptocurrency firms to focus on data center design to cut costs and boost power. But this type of radical energy efficiency may soon be key to America's effort to build an exascale computer and the increasingly extreme data-crunching requirements for cloud and analytics.
...they want their cooling back: Cray-2
I was actually one of the admins for a Cray-2 (and other systems) at NASA LaRC from 1988-1992. It was pretty cool (no pun intended). The chassis was Plexiglas (or something else clear) and you could see the 3D circuit boards immersed in the Fluorinert - which was wicked expensive back then. I always wanted to put some plastic fish inside the system... The system was moved to the Virginia Air and Space Center (VASC) for a while after being decommissioned sometime later.
It must have been something you assimilated. . . .
