Telecity Powergate datacentre
TelecityGroup's Powergate co-location facility in west London (above) is used as a spillover capacity site for data from the company's five Docklands-based and two City-based datacentres.
The facility has a PUE rating of around 1.65. As a co-location provider, Telecity is not able to choose the hardware in the facility, but it has some control over how it can increase energy efficiency.
It offers varying levels of security to companies, ranging from open racks (left) to cages (centre back) to cages with biometric and/or password protection (right).
