The FIT4Green project has produced an energy-aware plug-in that reduces data centre energy consumption by more than 20%.

ICT as a whole is responsible for about 2% of global CO2 emissions, which is equivalent to the global CO2 emissions of aviation. Data centres are a significant part of ICT. The energy related costs total over 40% of data centres’ expenses.

FIT4Green, an EU project, which began in January 2010, concentrated on finding new solutions for saving energy in data centres.

The project designed and implemented an energy-aware plug-in on top of the current data centres’ management tools to orchestrate the allocation of ICT resources and turning off unused equipment.

The project achieved its goal with a 20 % direct ICT equipment energy savings without compromising compliance with Service Level Agreements (SLA) and Quality of Service (QoS) metrics.

The achieved savings in CO2 emissions were similar to the energy savings.

The direct energy savings in the ICT equipment induce remarkable additional savings due to the reduced needs for cooling, for example.

FIT4Green plug-in is designed to be applicable to any data centre type.

The plug-in was validated in three representative data centres:

VTT’s work in the project concentrated on the optimizations in the supercomputing scenario.

The target of 20% was reached in each test bed, and in some cases the savings were up to 50%.

The comparison point for all the savings was the same system without any energy optimizations.

All the 16 public deliverables of the project are freely available on the project web site.

The plug-in code has also been released as open source software.

FIT4Green was coordinated by GFI Informática with HP Italy Innovation Centre as the technological leader.

Other partners besides VTT were University of Passau, Jülich Supercomputing Centre, Imperial College London, University of Mannheim, Create-Net, Eni S.p.A., and Almende BV.
