Cassatt recommends that organizations use Active Power Management software to turn off idle servers. The goal: reducing data center power costs and reclaiming capacity.
However, using policy to turn on and off servers is a new approach that many organizations haven't tried before. What do the experts say about using a power management approach of this type in your data center? We've gathered recommendations from notable industry leaders on the topic, and you might be surprised how much they agree it's an approach worth pursuing. Take a look:
US EPA: "Enable power management on 100% of applicable servers; Enable power management at data center level of applications, servers, and equipment for networking and storage"
~ EPA Report to Congress on Server and Data Center Energy Efficiency, August 2007 (executive summary, table ES-1)
www.energystar.gov/.../EPA_Report_Exec_Summary_Final.pdf
"The EPA [U.S. Environmental Protection Agency] is currently working alongside various industry groups to develop Energy Star products and rating systems for energy-efficient data centers," said Andrew Fanara, U.S. EPA Energy Star product development team lead. "We have for some time recognized the energy-saving opportunity to actively power-manage idle servers in the data center, and are encouraged that private sector vendors like Cassatt are taking their own energy efficiency initiatives in this space."

"If current trends continue, U.S. data center power consumption will nearly double from 2005 levels by 2011," said Jonathan Koomey, consulting professor at Stanford University and a key contributor to the EPA's 2007 Report to Congress on Server and Data Center Energy Efficiency. "Server power management technologies can be effective in improving energy efficiency in data centers and alleviating the power and cooling constraints faced by many of these facilities."

The 451 Group: "...we believe that power management will be an important technology that runs through the entire movement working towards greater eco-efficiency in IT... ...[that] datacenter power management will not only be a separate market, but a growing one."

The Uptime Institute: "...The Institute's research indicates that the savings which could be realized from effective and reliable energy-save features could be substantial in many cases ...and to mandate their use within their IT organizations. Simply abandoning the idea of energy-save features leaves a potentially large efficiency opportunity untapped."

Emerson Power: "More sophisticated power management - enabling power management features provides tremendous savings... More sophisticated controls that would allow features to be enabled only during periods of low utilization, or turned off when critical applications are being processed..."
