‘Optimised Cooling’

Date: 19th April 2010

Data Centre Management 010310Yorkshire Water has reduced power consumption at its data centre in Bradford, South Yorkshire, by 25 per cent following an Energy Assessment undertaken by Keysource. Following implementation of key recommendations, Yorkshire Water was able to optimise the cooling processes within the facility and achieve annual cost savings of up to £70,000.

Keysource was appointed by Yorkshire Water to conduct the energy assessment to provide a review of its data centre’s energy use and see how the company could reduce the overall operating costs and environmental impact of the facility. It provided a performance snap shot for the 50-rack computer room and a recommendation report that outlined a number of suggested changes.

Utilising the Green Grid metrics for measurement, Keysource measured the facility’s Power Usage Effectiveness (PUE) figure at 2.3, which meant that only 43 per cent of the total facility load was being used to power IT equipment. A second assessment that took place after a 12-month period found that the implementation of the recommendations had resulted in an improved PUE with 59 per cent of the total facility load being used to power IT equipment.

The improvements can be attributed to Keysource undertaking a full Computational Fluid Dynamics (CFD) analysis of Yorkshire Water’s data centre, which helped stakeholders understand airflow issues. As a result Keysource recommended the use of blanking panels, floor grille relocations, deployment of racks in hot and cold aisles to optimise airflow management and the introduction of a third cooling unit to improve efficiency.

Shakil Azam, IT Service Provisions & Data Centre Manager commented: “Keysource’s Energy Assessments and recommendations proved essential for our ongoing commitment to reducing energy consumption from our IT infrastructure. By working closely with Keysource, we have tapped into their extensive data centre knowledge and expertise, to achieve significant performance gains in terms of reduced costs and carbon emissions.”
