Facebook has a new server farm in Lulea, Sweden.
Facebook has a new server farm located in the northern Swedish city of Lulea.
Facebook’s Lulea plant is the firm’s first facility outside the U.S., in a location chosen because the fierce cold will help to keep the company’s racks of high-performance computers cool.
The company looked at several sites across Europe, and picked Lulea for its cold climate. The move will see Facebook become faster for European users.
“Facebook has more users outside the U.S. than inside,” said Tom Furlong, Facebook director of site operations.
“It was time for us to expand in Europe.”
Tom Furlong said users across Europe would get better performance from having a node for data traffic closer to them.
Facebook currently stores data at its sites in California, Virginia and Oregon and is building another facility in North Carolina.
Companies rely on additional data centres not only to provide faster connections for people nearby, but also as backup in event of a system failure.
BlackBerry’s recent service collapse showed how much damage can be caused by companies having too few data centres to shoulder the load if one hits a technical hitch.
Lulea is located 60 miles (100 kilometers), south of the Arctic Cicle and lies near hydropower stations on a river that generates twice as much electricity as the Hoover Dam on the border of Nevada and Arizona, Facebook said.
In case of a blackout, construction designs call for each building to have 14 backup diesel generators with a total output of 40 MW.
Facebook’s Lulea data center, which will consist of three 300,000-square foot (28,000-square meter) server buildings, is scheduled for completion by 2014. Lulea site will need 120 MW of energy, fully derived from hydropower.
While many server farms rely on chiller systems, Facebook’s will use an advanced cooling system powered by evaporating water.
For around eight months of the year, Lulea plant will cool itself using the icy outside air.
The heat from the server racks will also warm up the offices at the plant.
Facebook didn’t comment on the price of its investment, but Lulea officials have previously projected construction costs of up to 5 billion kronor ($760 million).
“We knocked on doors at Facebook’s head office (in Palo Alto, California) and today they’re moving in to Lulea – this is huge, really huge,” said Matz Engman, who heads the Lulea Business Agency, a public-private partnership working to attract businesses to the region.
As winter temperatures well below freezing and summertime highs that rarely climb above 80F (25 degrees C), Lulea has used its frigid climate as a selling point in its efforts to establish itself as a hub for server farms.
It was reported that other Nordic cities have adopted similar strategies.
Google purchased a paper mill in Hamina, southern Finland, two years ago and turned it into a data center, using seawater from the Baltic Sea for its cooling system.
Servers inside data centers are the backbone of Internet services such as Facebook. The servers store and transmit billions of status updates, links, photos and all the outside apps used by Facebook’s members.
