Power-systems company Global Power Supply announced that Facebook's now infamous data center in Prineville, Oregon, has some of its products ensuring adequate power back-up.

In a statement GPS said the client required a custom-designed system and back-up generators that could handle the demands of the facility's massive server loads. The vendor is also providing services and support for its products, although it did not specify which products have been deployed at the site.

Jay Park, director of data center design and construction at Facebook, said: "Global Power Supply has been a valuable member of our data center deployment team, their expertise in standby power applications as well as their competent and responsive project management approach has allowed us to meet our project goals."

Facebook has released a lot of details about the design of its Oregon data center, the first the company built for itself. Through opencompute.org, it released design documents for the facility's power and cooling systems, as well as the custom-made servers running its applications.

In brief, the electrical system uses 480/277VAC distribution with a 480VDC UPS system, integrated with a server power supply. Power is fed through a dedicated 115kV substation.

Diesel back-up generators have a standby rating of 3,000kW/3750kVA.

As it is continuing to expand capacity at Prineville, Facebook is well on its way to completing its second data center in Rutherford County, North Carolina. In an update on the North Carolina data center's Facebook page, the team said it had successfully fired up medium-voltage switchgear at the site.

Facebook is using a combination of colocation facilities and its own data centers to support its massive social-networking application.
