HP Labs Develops New Tech for Cooling Data Centers

By NewsFactor Network | December 21, 2006

HP Labs research center has developed a new approach to cooling data centers by adjusting air-conditioning systems to changing server loads more precisely than what’s available now.

HP says its Dynamic Smart Cooling (DSC) technology, which the company claims can deliver 20% to 45% savings in cooling energy costs, depending on the size of the data center, will be available in mid-2007.

DSC involves placing several heat sensors on racks of servers throughout the data center, which send information on changes in temperature to a central monitoring system. As the sensors detect an increase in a server’s temperature, a signal is sent to the nearest of several air-conditioning units to throttle up to cool that server. When the server cools down because it’s not doing as much computing, the air conditioner throttles down.

HP, which first introduced the concept of Dynamic Smart Cooling in 2003, revealed a number of additional program details recently. It announced creation of a Data Center Solution Builder program with design partners that will work with HP to implement a DSC solution, which can be retrofitted into an existing data center.

HP has started trials of the technology is going to implement DSC in new data centers for its own operations at six U.S. locations.

Also, Pacific Gas & Electric Co., the power utility serving Northern California, will make rebates available to data centers that deploy DSC, said Mark Bramfitt, of PG&E.

DSC is a way of addressing an energy consumption problem data centers didn’t have just five years ago, said Chandrakant Patel, an HP Fellow and one of the system designers.

“Five years ago, no one got fired for wasting energy but they did get fired if the server went down,” Patel said.

But today, energy consumption is an issue and Dynamic Smart Cooling technology addresses data-center…
