Rackspace's datacentre in Slough has been built to balance efficiency with ease of access, as its managed hosting business requires it to offer a variety of services that include the rapid swapping out of servers.
It is also the cradle for Rackspace's UK-based cloud, and the company has plans to expand the facility by a further 17,000 square feet in August in a bid to boost its compute capacity. It also wants to make it more efficient by introducing some free-air cooling.
