Oct. 24, 2007 Hewlett-Packard is reporting a 20% drop in energy use at a reseach data center in Bangalore, India, in the largest deployment of its Dynamic Smart Cooling system to date.

HP tested its new cooling system under real-world conditions at the 70,000-square-foot data center, one of the largest in India. The facility, a consolidation of 14 HP labs in Bangalore, features a mix of older equipment and newer server racks and blades.

The cooling system employs a network of 7,500 sensors to yield real-time data center air-temperature measurements, which it then uses to respond to facility failures, anomalies, and brownouts.

Once fully optimized, HP expects its new facility to use 40% less energy than a typical data center, saving 7,500 megawatt-hours (MWh) and reducing carbon dioxide emissions by about 7,500 tons each year.

Among IT executives greatest concerns today are power, cooling and energy efficiency, said Jerald Murphy, senior vice president and research director of the Robert Frances Group, an IT consulting and research firm. As companies look for solutions that help move them toward highly efficient data centers, they need to make smart changes today. Companies can reap incredible power savings without having to completely rebuild their data centers.
