Like the unfortunate person who continually diets but only seems to gain more weight, power-hungry data centers — despite adopting virtualization and power management techniques — only seem to be consuming more energy than ever, to judge from some of the talks at the Uptime Symposium 2010, held this week in New York.
“There is a freight train coming that most people do not see, and it is that you are going to run out of power and you will not be able to keep your data center cool enough,” Rob Bernard, the chief environmental strategist for Microsoft, told attendees at the conference.
Power usage is not a new issue, of course. In 2006, the U.S. Department of Energy predicted that data center energy consumption would double by 2011 to more than 120 billion kilowatt-hours (kWh). This prediction seems to be playing out: An ongoing survey from the Uptime Institute found that, from 2005 to 2008, the electricity usage of its members’ data centers grew at an average of about 11 percent a year.
But despite all the talk in green computing, data centers don’t seem to be getting more power-efficient. In fact, they seem to be getting worse.
