September 24, 2009, 9:25 PM — Data center managers should turn server temperatures up to 75 degrees Fahrenheit, and adopt more aggressive policies for IT energy measurement, Gartner says in a new report.
After conducting a Web-based survey of 130 infrastructure and operations managers, Gartner concluded that measurement and monitoring of data center energy use will remain immature through 2011. Only 7% of respondents said their top priorities include procurement of green products and pushing vendors to create more energy efficient technology. In general, data center managers are not paying enough attention to measuring, monitoring and modeling of energy use.
“Although the green IT and data center energy issue has been on the agenda for some time now, many managers feel that they have to deal with more immediate concerns before focusing attention on their suppliers’ products,” Rakesh Kumar, research vice president at Gartner, said in a news release. “In other words, even if more energy efficient servers or energy management tools were available, data center and IT managers are far more interested in internal projects like consolidation, rationalization and virtualization.”
About 63% of survey respondents expect to face data center capacity constraints in the next 18 months, and 15% said they are already using all available capacity and will have to build new data centers or refurbish existing ones within the next year. In a troubling sign, 48% of respondents have not yet considered metrics for energy management.
Gartner issued four recommendations for improving energy management:
• Raise the temperature at the server inlet point up to 71 to 75 degrees Fahrenheit (24 degrees Celsius), but use sensors to monitor potential hotspots.
• Develop a dashboard of data center energy-efficient metrics that provides appropriate data to different levels of IT and financial management.
• Use the SPECpower benchmark to evaluate the relative energy efficiency of servers.
• Improve the use of the existing infrastructure through consolidation and virtualization before building out or buying new/additional data center floor space.
