Tech giant Microsoft has started dipping its servers in liquid to make them more energy efficient and improve their performance, according to a report by The Verge. This isn’t the first time the company has made promises of a liquid-based solution. The data center was moved to the ocean in 2018. Called Project Natick, 864 servers and approximately 27 petabytes of storage were tossed to the bottom of the Scottish Sea.
Back to the present, the Redmond-based tech giant has started dipping its server rack into one Liquid bathThe fluid used for the process is a non-conductive fluorocarbon based fluid. It absorbs the heat from the server components through direct contact. According to the report, the liquid reached a lower boiling point at 50 degrees Celsius. Then the liquid condenses and rains again in the bathroom. The process starts again as a cycle, as a closed cycle cooling System. No cooler is required to condense the liquid, and no energy is required to move the liquid in the liquid bath, the report said.
The liquid bath-based cooling also allows the company to pack the hardware closer together, reducing the footprint. Compared to air cooling, the smaller space would accelerate the cooling via liquid baths. The company is currently only experimenting with the new approach and examining whether this method is reliable enough for future use and how it could benefit the cloud and AI.
