New Technology Slashes Data Center Energy Consumption

A new energy-aware plug-in can reduce energy consumption in data centers by more than 20 percent, according to researchers with the European Union-funded Federated IT for a Sustainable Environment Impact (FIT4Green) project.
Experts from industry and academia designed the technology to work on top of the current management tools used by data centers to organize the allocation of information and communications technologies resources and turn off unused equipment.
The FIT4Green plug-in does not compromise the equipment's compliance with service-level agreements and quality-of-service metrics. The plug-in is designed to work in any data center type, and the savings ranged from 20 percent to as much as 50 percent during testing. Moreover, the savings in carbon dioxide emissions were on the same scale as the energy savings, while direct energy savings for information and communications technology gear also induced additional savings due to reduced cooling needs.
One of the project participants, the VTT Technical Research Center, mainly focused on optimizations for supercomputing applications. The technology is now available to data centers, while the plug-in code has been released as open source software.
