Google is building a new computing center that could house up to 450,000 servers. Could you imagine what it would sound like if they were all jet engine fan cooled?
“The computer servers that fill huge data centers are producing more heat with every new generation of processors. It’s a problem that’s sending engineers on a search for cooling fans that are both small enough to fit inside ever-smaller server chassis and powerful enough to dispel increasing amounts of heat. At Hewlett-Packard, they’ve found one answer in an unexpected place: model jet airplanes.
To cool its next generation of commercial servers, the company is using electric-ducted fans (EDFs), originally developed by model airplane hobbyists to power radio-controlled jets. Essentially propellers in a box, the fans run so fast and produce so much air pressure that they should be able to provide the cooling needs for the next several generations of HP servers, according to Wade Vinson, an engineer in the company’s Industry Standard Server Group.
