ABSTRACT: COOLING TRENDS IN DATA CENTERS
Shlomo Novotny, Vice President and Chief Technology Officer, Vette Corp.
One of the most critical sustainability issues with many data centers today is cooling. This is a result of the limitations of air cooling, which creates a very costly, complex, and inefficient infrastructure. Localized, passive, low-power dissipation liquid cooling devices at either rack level or rack proximity, when compared to traditional air-cooled methods, have the capability of reducing the power consumption of in-room cooling devices by as much as 90%. In addition, by allowing data centers to operate with higher-density racks, rack-level liquid cooling can reduce the data center IT footprint by as much as 80%. The beauty of augmenting existing cooling architectures with liquid-cooling at the heat source is in extending the viable life of a data center. It saves up to 10x when compared with the costs associated with building new facilities.
