During peak hours, admins want their servers fully charged and running at full bore to ensure their apps are delivered without annoying service lapses. But during non-peak hours, there's no logical reason why machines need to feed on as many watts of energy.

But during non-peak hours, there’s no logical reason why machines need to feed on as many watts of energy.In an effort to help cut down on that energy waste — and the associated energy and cooling bills — Citrix today announced a new PowerSmarts feature for its Citrix Presentation Server line, which lets admins set policies to “automatically dial server power down based on application traffic levels,” according to the company.The company claims the feature can help customers datacenter energy consumption costs by up to fifty percent, a rather impressive claim if it’s accurate. “The key to any effective response to green IT challenges is to be able to maintain, and even increase, the capacity of IT infrastructure while reducing its energy consumption,” said Scott Herren, Citrix group vice president and general manager of the Citrix Application Virtualization Group. “By powering down unused Presentation Servers during off-peak usage, we are helping our customers be more green and at the same time putting money right back into their wallets.” Citrix also announced that HP is the first company with hardware to support the PowerSmarts feature in its HP ProLiant portfolio.Notably, HP itself unveiled a power-capping feature of its own earlier this year called HP Insight Power Manager, part of the company’s Systems Insight Manager (SIM) hardware management platform. PowerSmart is compatible with all current versions and editions of Citrix Presentation Server and iLO-enabled HP servers. It will be available in December to all Citrix Presentation Server customers as a free download at www.citrix.com/cdn. Technology Industry
