Experian Cold Aisle Containment Testimonial
When Experian decided to look at reducing energy bills in their Data Centres they contacted our cold aisle containment manufacturer. As the density of equipment in the Data Centre increases so correspondingly does the heat output, which in turn places further pressure on the cooling systems required to keep the Data Centre cool. Of the total power required to run a Data Centre, up to 40% of it is necessary to keep the environment cool. By deploying cold aisle containment cooling power can be reduced by 25%. The low density area in Hall B with 75 server racks arranged in 3 aisles was chosen for the trial to prove the efficiency of retro-fitting containment to the cold aisles in this area. The aims were to prevent hot and cold air mixing, and reduce the volume of cold air needlessly re-circulating back to the CRAC units without being passed through the racks. The chosen solution was a cold aisle containment with ClearPath double self-closing doors at each aisle end, and drop down roof panels suitable for the water fire suppression system. The objectives of the project were simple:
- Increase power usage effectiveness in the company’s Data Centres and reduce energy costs.
- Support the company’s efforts in achieving their Corporate & Social Responsibilities objectives.
One key aspect of the chosen solution was the installation. At no point is it necessary to open a cabinet door since the system attaches to the cabinet’s external frame. Following completion of the installation the room was left to stabilise its air distribution. Two days later the air temperature and floor static air pressure measurements were taken. The room temperature had remained constant, floor plenum static pressures had increased by 80% and the cooling demand on the CRAC unit closest to the low-density area had reduced by 15%. Four CRAC units were then progressively turned off to compensate for the increase in floor static pressures, and the hall left to stabilise to ensure there was no undue rise in air temperature. The results were impressive; estimated total savings are £34,952 per annum gained from turning off 4x CRAC units, the reduction in PUE (Power Usage Effectiveness) from 2.0 to 1.93, leading to a reduction in Experian’s carbon footprint, and illustrating the company’s commitment to its Corporate & Social Responsibilities.
- Maximise the performance and life expectancy of IT equipment.
- Provides a simple and non-intrusive solution for reducing cooling power costs.
- Avoid the cost of acquiring new facility space if cooling capacity is constraining IT growth.
- Estimated total annual savings £34,952
- Payback in 10 months.
- C&SR – PUE reduced from 2.0 to 1.93.
After reviewing the performance Paul Dennis, Experian Technical Facilities Manager UK & Ireland said:
“When we looked at our options for retro-fitting Cold Aisle Containment into the chosen trial area, our greatest concerns were its ease of installation and compatibility with our fire extinguishing system. Having looked at the options available, the chosen solution was the natural choice.
From initial discussions through design & installation, to the final hand over, the process was seamless.
Based on the present level of savings being realised by the trial area, we have decided to undertake the full fit-out of our server areas using this system.”
