Data Centres: Building Up: Nine-Foot High Server Racks

Wednesday, March 24th, 2010

How do you get more mileage out of your data center space?

Some companies in the US are building up, rather than out. By using taller racks and cabinets, these users are able to pack more servers into each square foot of data center space. This practice is being reported in leased data center facilities designed to support higher power densities.

“Our customers are more and more sophisticated, and now they understand that power density is just a matter of how high the racks can go,” said Hossein Fateh, President and CEO of DuPont Fabros Technology. “You can build vertically as well as horizontally, and when you build your rack higher they don’t have to pay extra for it. To be more efficient, they will build a nine foot rack. We just went through the exercise with one customer who hadn’t done it before.”

A standard server rack is seven feet high and can accommodate 42 units (42U) of rackmount server equipment in a 19-inch wide slot. There are many options in rack size, with manufacturers offering enclosures that are up to 23 inches wide (a size often used for telecom equipment) and height options ranging from 44U and a nine-foot tall 58U rack.
