Electricity produced by on-site diesel generators can cost three times as much as power bought from the grid. But data center owners have few choices. Fuel cells are still too small and too expensive. Small natural gas turbines are becoming more common, but have yet to capture significant market share. Indeed, backup power equipment has become as essential as fiber-optic cable.
Power supply plays a very big part of that.
The power redundancy provided by the diesels is one of the most expensive parts of a data center, Moore said. They simply have to have the horsepower to keep the lights on. A question here. Is the problem. After a year of first-class cruising on DSL, I got bumped back to steerage.
