Rackspace's Slough-based datacentre houses the hardware for its UK cloud, along with the other servers rented by its customers. It has 1,600 racks in place, of which 120 support its cloud.
The datacentre, in operation since June 2008, was in the process of being expanded when ZDNet visited in 2011, with the company adding a further data hall. At the same time, Rackspace is bringing in new cooling systems to increase the efficiency of the site and cut its power costs.
Rackspace's server hardware is predominantly supplied by Dell. It operates a multi-vendor networking approach: Cisco is the predominant provider of switching technology, while Juniper Networks supplies backbone services and Brocade provides equipment for load balancing.
