Over the past two and a half years, the VTT Technical Research Centre of Finland has been involved in a project that seeks solutions for saving energy in data centres. The EU project, called FIT4Green, designed and implemented an energy-aware plug-in that can be installed on top of the data centres’ management systems and which coordinates the allocation of ICT resources and turns off unused equipment.
The plug-in can help data centres to achieve 20 per cent direct energy savings in their ICT systems. Major savings can also be achieved in carbon dioxide emissions, depending on the energy sources utilised by the data centres. In addition to direct energy savings, reductions are also possible through the decreased need to cool the equipment.
The FIT4Green plug-in was designed to adapt to all types of data centres. VTT’s role in the project focussed on optimisations in a supercomputing scenario in which a single centre’s savings depended on the utilisation rate of the system. Each of the test beds achieved the targeted 20 per cent savings, in some cases with figures rising up to 50 per cent. The comparison points for the savings were the same systems without the energy optimisation.
GFI Informática organised FIT4Green and HP Italy Innovation Centre was the technology leader for the project. Other partners in the project were, in addition to VTT, the University of Passau, the Jülich Supercomputing Centre, Imperial College London, the University of Mannheim, Create-Net, Eni S.p.A., and Almende BV.
