A smarter algorithm could cut energy use in data centres by 35%

Date: 3rd May 2013

New research suggests that data centres could significantly cut their electricity usage simply by storing fewer copies of files, especially videos. For now the work is theoretical, but over the next year, researchers at Alcatel-Lucent’s Bell Labs and MIT plan to test the idea, with an eye to eventually commercializing the technology. It could be implemented as software within existing facilities. “This approach is a very promising way to improve the efficiency of data centres,” says Emina Soljanin, a researcher at Bell Labs who participated in the work. “It is not a panacea, but it is significant, and there is no particular reason that it couldn’t be commercialized fairly quickly.”

With the new technology, any individual data centre could be expected to save 35% t in capacity and electricity costs—about US$2.8 million a year or US$18 million over the lifetime of the centre, says Muriel Médard, a professor at MIT’s Research Laboratory of Electronics, who led the work and recently conducted the cost analysis.

Keysource says: It is exciting to see new IT innovations that will contribute to significant reductions in energy consumption. However, many data centre owners are missing a trick by not integrating the physical M&E infrastructure with the technology infrastructure, to centralise monitoring, management and intelligent capacity planning of a data centre’s critical systems.

Using a proven Data Centre Infrastructure Management solution it is possible to achieve complete visibility over all assets to support faster and more informed decision making, because you can’t improve what you don’t understand. This will help utilisise the infrastructure to increase operating efficiencies and reduce energy consumption.
