The powerful tape technology can address data security with tape encryption as well as long term data protection.
Discover what disk and tape really cost -- and which solution provides lower total cost of ownership and optimizes energy use for your organization
The Clipper Group explores the truth behind the myths of tape, digging into the misconceptions in the disk vs. tape debate.
Over two thirds of disk-only users look to add tape back into storage infrastructure according to recent survey.
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 Tuesday. 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 management concerns about the operating expense of powering and cooling, said Paul Perez, vice president of HP's Technology Solutions Group.
At a demonstration of the technology for media Tuesday at HP Labs in Palo Alto, Calif., journalists could see that the data center in a nearby room was using 117 kilowatts of electricity to stay cool. But when the DSC system kicked in, consumption dropped to 72 kilowatts.
