Equinix also allows customers to vary their cabinet size and alter installation options. Some customers have chosen to cage below the floor, or to the ceiling of the centre, or even have specialised equipment. The company also takes delivery of equipment on behalf of customers and has built separate rooms within the facility for secure storage, as well as a build room for customers to test equipment before bringing it to the cages.

Outside of the co-location farms are the computer room air conditioners, or CRACs. These are pressure controlled and connected to a dual-reticulation chilled water pipe system that runs below the access hallway (pictured).
Chilled water is provided from the mechanical plant in the centre, which also contains a massive chilled water buffer tank. This tank, which will be augmented with a second in the future, is able to provide 24 hours of cooling for a full design load. It is kept cooled at all times so that in the event of a power failure, where the centre's chillers and pumps are required to restart, cooling is maintained.
