Digitial Realty in London - Five halls
Each data hall has staging workspace for technical operations, with lift access, power and cooling facilities throughout. The vast data halls are also kept cool with the help of 14 CRAC (computer room air conditioning) units that can be found operating in an N+2 configuration (providing back ups) in each of the 1,000 square foot pristine data halls.
The datacentre halls are raised 4m above ground level and have an 800mm raised floor. The floor can take loads of up to 12.5KN/m².
