Barclays to build energy-efficient datacentre with HP technology

Barclays has started an 11-month project to slash its carbon footprint by building an energy-efficient datacentre facility using Dynamic Smart Cooling technology from HP.

The project is part of the bank's five-year programme to reduce CO2 emissions by 20% per employee and cut the ratio of CO2 consumed against profit from 16.6 tonnes per million pounds of income down to 12.6 tonnes.

The smart cooling technology, which is being fitted in a new Barclays datacentre in Gloucestershire, would allow the bank to control cooling and so reduce electricity consumption. It will play a major part in helping Barclays achieve its carbon reduction target.

HP Dynamic Smart Cooling technology is designed to actively manage a datacentre's air-conditioning to deliver the right amount of cooling where it is needed.

Elaine Heyworth, head of environmental management for the global, retail and commercial banking division at Barclays, said, "The HP design uses two heat sensors on each server rack in the datacentre to focus cooling to where it is needed." Rather than cooling the whole datacentre, she said, "Smart Cooling allows us to reduce the amount of power we use to cool the equipment."

The system uses control software fed by continuous, real-time air-temperature measurements from the network of sensors throughout the Barclays datacentre to continuously monitor and adjust cooling equipment based on demand from the servers and storage devices.

As the air conditioners are used more efficiently Barclays is expecting to reduce its consumption significantly. "We expect to save 7,000 tonnes of CO2 per year,"

Heyworth said. Automatic temperature monitoring through Dynamic Smart Sensor should also enable the Barclays datacentre to respond faster to changes in temperature.

HP said this would put less strain on the chillers that cool the air around the datacentre.
