HP and Barclays have signed a letter of intent to introduce HP technology to reduce energy consumption and carbon emissions for the new Barclays Data Centre in Gloucester, UK. HP Dynamic Smart Cooling technology along with other measures will allow Barclays to save up to 13 per cent of total energy used for its Data Centre. It is estimated that the Data Centre will reduce its carbon footprint by around 7,470 metric tonnes of carbon dioxide (CO2) per year. The HP Dynamic Smart Cooling technology manages a Data Centre's air conditioning to deliver the appropriate cooling to where it is needed using real time air temperature measurements. Barclays and HP are cooperating on power-optimized servers, HP BladeSystem and HP Thermal Logic technology adoption and virtualization-based consolidation. Barclays claims that energy savings achieved already range from 18 per cent per server to 40 per cent energy savings per Data Centre.
