Efficient data center in Sefton, United Kingdom
Previously, the Council’s IT systems were disjointed and expensive. Now, a single data center in Bootle is home to the Council’s IT system, servicing 4,000 users at over 250 locations. As well as speeding up processes, the new technology is helping the Council to save costs by being more energy efficient. Compared to the previous data center, the new site emits 14.85 tons less CO2 per year thanks to a number of carbon reduction measures.
One major area where organizations can waste a lot of energy is through cooling IT hardware, which could otherwise become too hot and reach critical temperatures. To stop components overheating, Arvato introduced an energy-effi cient cooling system that uses hot and cold aisle containment, with one zone conducting cool air to the servers, and the other channeling the waste heat away. The separation of the air streams increases the effi ciency of the cooling system and keeps the hardware at optimum temperatures.
Furthermore, Arvato virtualized over 250 of Sefton’s physical servers. A virtual server shares a central high-powered physical server with other virtual units. The processor power is allocated based on demand. This avoids poor performance during periods of high usage, a historical problem with physical servers which have fi xed processor and memory availability. As most servers do not experience constant high demand – especially during non-work hours – processing power is reduced, which means the data centre needs less power and cooling.
These measures and others – such as using proximity sensors to control lighting – have reduced the Council’s energy consumption by 28,000 kilowatt hours per year – the equivalent of the annual energy consumption of six families. Not only has this helped to minimize the Council’s impact on the environment, but it also generates cost savings of roughly EUR 4,500 per year.
