IBM green datacentre
IBM's 'green datacentre' in Poughkeepsie, New York has been designed as a showroom of 'best practices' for datacentre design. The facility, which performs workloads for IBM and some of its customers, has an air-cooled side and a water-cooled side.
It pumps in water from the nearby Hudson River to cool its racks and employs energy-saving techniques such as rear-door heat exchangers. Tidy cable management and heat-mapping help bring its PUE down to about 1.27.
