University of Leeds trials submerged servers
The University of Leeds is running fully immersed servers, claiming 80 percent to 97 percent power consumption savings over traditional air cooling.
The University worked with Iceotope to fully submerge its servers for cooling purposes instead of using traditional air fed cooling systems. Using 3M’s Novec liquid, the non-conductive liquid allows electronics to be submerged in it without damaging the equipment. The liquid is pumped directly to the servers and uses a heat exchanger system to carry away the heat. The University claims that the liquid cooling system uses 80 watts of power to cool clusters that use 20 kilowatts and claims the system does away with the need for traditional data centre support services such as air conditioning or air purification units.
Jon Summers, from the University of Leeds School of Mechanical Engineering department said, “The liquid we are using is extraordinary stuff. You could throw you r mobile phone in a tub of it and the phone’s electronics would work perfectly. But the important thing for the future of computing and the internet is that it is more than 1,000 times more effective at carrying heat than air.”
