Microsoft is now submerging servers into liquid baths – Tom Warren

Microsoft is starting to submerge its servers in liquid to improve their performance and energy efficiency. A rack of servers is now being used for production loads in what looks like a liquid bath. This immersion process has existed in the industry for a few years now, but Microsoft claims it’s “the first cloud provider that is running two-phase immersion cooling in a production environment.”

The cooling works by completely submerging server racks in a specially designed non-conductive fluid. The fluorocarbon-based liquid works by removing heat as it directly hits components and the fluid reaches a lower boiling point (122 degrees Fahrenheit or 50 degrees Celsius) to condense and fall back into the bath as a raining liquid. This creates…
