CGGVeritas liquid-cooled datacentre, Texas
Some datacentres are pushing the boundaries of cooling tech, for instance by dipping IT systems in liquid. Green Revolution Cooling says its dielectric coolant provides the most efficient cooling and lowest cost per watt in the industry, reducing total energy consumption by 95 percent.
Here are two quads with eight racks and two water modules each as part of the CGGVeritas installation in Houston, Texas, which boasts 24 racks with 600KW capacity.

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.

GE datacentre, Kentucky
General Electric's Adrian Shankln, Global Data Center Manager (above), shows off one of the racks of new high density servers in GE's $48m state-of-the-art datacentre in Louisville, Kentucky.
The facility is one of the first in the world with LEED Platinum certification. LEED stands for Leadership in Energy and Environmental Design and is awarded by the US Green Building Council for projects that go above and beyond standard building codes to create sustainable, energy-efficient buildings. It's tough to get the basic LEED certification, and only six percent of all LEED buildings achieve the Platinum certification.
The site has a rich history: in 1954, the Louisville GE complex became home to the first UNIVAC computer deployed in a private business (before that, all computers were part of government projects).
