|An Overview of the Water Cooling System for the IBM Power 575 Supercomputer|
|Keywords: Server, Water, Cooling|
|A technical perspective and review of water cooling technology as implemented in the recently announced IBM Power 575 Supercomputing System will be given. The use of indirect (cold plate) water cooling in combination with air-to-water cooling via a Rear Door Heat Exchanger (RDHX) will be described. The heart of the water cooling system, the Water Conditioning Unit (WCU), which distributes water to the multiple computing nodes as well as the RDHX, controls the cooling system water temperature, and transfers the system heat load to the building facilities cooling water will also be described. Attention will also be given to why water cooling was chosen and to what may lie ahead for future water cooled systems.|
