University report: Increased web usage could heat up data centers

Many universities, including Georgia Tech, have searched for energy-efficient cooling strategies that could be adopted well beyond higher education.

Technologists at Georgia Tech have studied ways to cool high-performing computer centers designed to run large simulations and process enormous amounts of data — two functions that had a major impact on the local energy grid.

“Rather than junking the old machine, Georgia Tech decided that we could recycle it and use it for energy-efficient IT research along with a host of other uses,” said Karsten Schwan, director of the school’s Center for Experimental Research in Computer Systems (CERCS).
