“ It is our belief that in data centres , white space is gold and cabinets are diamonds ,” says Collier . Accordingly , the company emphasises achieving maximum efficiency for its clients , with clear examples of improvement . “ In a typical room , of around 10,000 square feet , the owner ’ s plan was to put in 418 cabinets . With Tier E / A , the owner could put 512 cabinets in that room . That ’ s 22 % or so more cabinets in the same space . Every one of those cabinets increases revenue . So if I can put 94 more cabinets in the same space , I have a compelling story to tell .”

Another crucial element of the data centre puzzle is uptime , with redundancy therefore being critical . “ What data centres typically look for is N + 1 redundancy . So for every four or five air handlers , designers add another for redundancy . But this does not provide effective redundancy unless the extra unit is adjacent to the unit that goes down . We , on the other hand , build a central mechanical equipment room and , by providing a mixing box , are able to provide true N + 1 redundancy
