The AIT Data Centre Audit identified total Data Centre loads of 148kW which costs Bedford Borough Council £88,178 per annum. The PUE (the ratio of “Total Data Centre Power Consumption” divided by the “IT Equipment Power Consumption”) of the Data Centre was estimated to be 2.1, roughly the current industry average.
Identified savings included:
- Adjusting humidifier settings to allow broader tolerances and reduce energy usage
- Retrofitting variable speed drives to fans and compressors
- Addressing poor air distribution issues to improve cooling and increase efficiency
- Elimination of hot air recirculation paths
- Use of a hot aisle separation system (HASS)
- Reduction in hot spots and raising of average temperature to ASHRAE standards
Many other resilience measures were also identified to improve the robustness of power and cooling systems in the Data Centre.
“The independent AIT Data Centre audit provided an evidenced based report clearly breaking down data centre running costs and giving clear targets to improve the resilience and efficiency of our Data Centre”, said Tony Pompa, Data Centre Manager, Bedford Borough Council. “It has helped focus our spend to best reduce our carbon footprint as well as provide real cost savings for the borough’s residents.”
By increasing Data Centre efficiency to a PUE of 1.5 by the audit showed that the Council would save over £37,000 per annum. The Council continues to drive down costs and are currently looking to install a free-air cooling system to further improve efficiencies.
