Asetek Inc., the world’s leading supplier of liquid cooling solutions for computers announced today that it will showcase a state of the art power efficient HPC cluster at SC12 in Salt Lake City, Utah - November 12-15. Formal presentations and live demonstrations will be available at Asetek’s booth #4045. The showcase is groundbreaking in the areas of power efficiency, performance and density. The cluster is built on an industry standard 48U rack, 46Us of which are filled with 23 2U 4-node Intel® H2216WPJR servers, each with dual Xeon® E5 2690 CPUs providing a total CPU and core count of 184 and 1472 respectively.
Under load, the fully populated rack consumes 37kW of power that is all converted in to heat. Using traditional server air cooling and room air conditioning, it would be impossible to run at these densities. In reality, it would require another 22kW of power just to keep it cool (Industry Average PUE 1.8/pPUE1.6). In the showcase cluster all CPU and memory heat, (85% of the total server heat generated) is cooled by Asetek’s warm water liquid cooling RackCDU™ system. As the servers are cooled by warm water, no power goes in to actively chilling the liquid. This means that 85% of all server generated heat is cooled by free ambient air.
The net result of using RackCDU™ in a data center is at least 50% savings on the cooling power bill, often times with immediate payback. Because the hot water generated from the RackCDU™ can be reused for facilities heating or cooling, data center operators now can achieve EREs of <1
