Mr Wayne Salter (CERN)
Over the past few years, CERN has been working to improve the efficiency of its main Data Centre that was built in the early 70s. Most of the equipment hosted in the Centre relies on an air-cooling infrastructure that was designed and installed many years ago. By applying small changes to the existing, and ageing, cooling infrastructure, CERN has significantly improved the energy efficiency of the Data Centre. This has permitted to cool more equipment with the existing infrastructure and to make important energy savings. This presentation reports on the most important steps taken to improve the cooling efficiency in the Data Centre and on the corresponding achieved savings.
