A UK data centre claims to have reduced its servers' energy needs by 40 per cent.
Ultraspeed, based in Shoreditch, said that it had dealt with the growing issue of power hungry servers by switching from AC power to DC and by opting for diskless servers.
The biggest savings came from switching the type of power the London data centre used. DC power is more efficient and the excess heat is created away from the server, reducing data centre cooling needs.
Jordan Gross, Ultraspeed commercial director, said: "The inherent stability and efficiency of DC power has been known for years yet very few companies operating large server farms actually use it.
"With a potential reduction in overall carbon emissions from that initiative alone of around 30 per cent, this is inexcusable."
Ultraspeeed has also cut its power needs by switching to servers without a hard disk. As most server crashes are caused by the single disk failure, removing the servers' storage capacity and transferring it to a storage area network (SAN) where data is replicated and accessible from different disks cuts down on server failures and cuts power consumption by ten per cent.
A third step the company introduced was using low-voltage processors, which according to the company produce more computing power per watt.
