Like the unfortunate person who continually diets but only seems to gain more weight, power-hungry data centres - despite adopting virtualisation 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.
Power usage is not a new issue, of course. In 2006, the US Department of Energy predicted that data centre 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 centres grew at an average of about 11% a year. But despite all the talk in green computing, data centres don't seem to be getting more power-efficient. In fact, they seem to be getting worse.
