Intel has endorsed Green Revolution Cooling’s CarnotJet submersion cooling system following one year of testing. Intel found that submerged servers used 7 per cent less energy at platform level due to removal of server fans and reduction of leakage currents in mineral oil coolant, and reported a cooling PUE (Power Usage Effectiveness) of 1.02-1.03, which means the CarnotJet system requires just three per cent of IT power to cool the IT servers. Modern data centres typically have a PUE of 1.6-1.7 and air-cooled servers that use 5-25 per cent more energy than submerged servers.
According to Green Revolution Cooling (GRC), Intel’s support for submersion cooling has bolstered sales of the product and the company has announced an installation base of more than a megawatt with a number of new installations on the way. GRC has also recently hired a Systems and Controls team to further refine the control system I/O for data centre integration. In addition, a factory server warranty from Supermicro for submersion-ready servers installed in the CarnotJet system has been announced.
