Immersion-Cooled Server Cluster - Intro

This is the first published video of our Immersion server cluster demo. It's a 4 node, 8 socket server chassis,with 48AMD Opteron cores. Thanks to AMD, Harddata and Hardware Labs for collaboration.

It was built to demonstrate the ability to "hot swap" nodes without disruption to the other nodes. It will also be used to study fluid loss mechanisms, junction-to-water performance, etc.

In this video, the nodes are idling immersed in Novec 7100 which boils at ~60C. The power draw is 600W. The fluid is being condensed by water that is pumped through a radiator.

Soon this machine will be on the network and we can put it through its paces. More data to come...

The one you see in the video is pretty lossy because it has a flip top lid with no gasket etc. This Winter it will be put into a metal case with a few refinements like a bellows and check valve. Our Apple G5 runs that way with essentially no losses until one opens it for some reason.

How often does the fluid need to be changed/topped off in a settup like that?
