Should these fail, the site has a diesel power generator, allowing the DNX to remain operating for hours even after the main power source has been lost. Other possible points of failure are covered off with redundant systems. There are multiple entrance points for network and power lines, and should one group of network lines fail, the others can pick up the slack. When all of the lines are running, this allows the DNX to have a very wide bandwidth. Climate control is another concern, and one that is not to be taken lightly.
Computers generate heat, which is bad for their circuits.
And naturally, with hundreds of high-power computers in a single room, a lot of heat is being created. The DNX has a high-tech climate control system, which keeps room temperature at a level where computers are safe from the risk of overheating or breaking down. But most important of all is the human element, since computers are not capable of maintaining or running themselves. The DNX is staffed twenty-four hours a day by personnel who are skilled at monitoring and supporting the servers. And that way, if something does break down, repairs will be conducted as quickly as possible.
