【超“酷”的公司:Facebook北极建数据中心】Facebook在距离北极仅70英里的瑞典吕勒奥建设了一个数据中心,占地4万多平米,相当于六个足球场,目前有150名工作人员,这里常年气温在零下50度左右,据了解,这种低温可以帮助数据中心节约约40%的电力。

That's really cool: Facebook gives rare glimpse inside its gigantic Luleå server farm just 70 miles from the Arctic circle

Mark Zuckerberg has given a rare glimpse inside one of Facebook's secretive server farms.
The Facebook boss said he is going to reveal more pictures from Facebook's facilities around the world.
To kick off the project, he revealed a stunning series of pictures of the firm's gigantic Luleå data center in Sweden.
'Over the next few months, I'm going to start posting some rare photos of the most advanced technology Facebook is building around the world,' Zuckerberg posted.
The Luleå data center opened in 2013, and was Facebook's first outside the US.
It is located deep in the forests of northern Sweden.

'It's a key part of our global infrastructure, and it uses a variety of local natural resources to increase efficiency and save power,' said Zuckerberg.
'The small town of Luleå is less than 70 miles south of the Arctic Circle, and it's typically pretty cold.
'The temperature in the area is below 50 degrees most days, so we use large fans to pull in the outside air to naturally cool the thousands of warm servers that line the center's broad hallways.'
A dozen hydro-electric plants operate on nearby rivers, providing a reliable and renewable power source.
The whole system is 10% more efficient and uses almost 40% less power than traditional data centers, Facebook claims.
'Inside, the main building is the size of six football fields,' said Zuckerberg.
'Nearly all the technology in the facility, from the servers to the power distribution systems, is based on Open Compute Project designs as well.
'You probably don't think about Luleå when you share with friends on Facebook, but it's an example of the incredibly complex technology infrastructure that keeps the world connected.

'I'm looking forward to sharing photos of more of our advanced technology soon.'
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.
Facebook didn't give 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.
With winter temperatures well below freezing and summertime highs that rarely climb above 80F (25 degrees Celcius), Lulea has used its frigid climate as a selling point in its efforts to establish itself as a hub for server farms.
Other Nordic cities have adopted similar strategies.
In 2009 Google purchased a paper mill in Hamina, southern Finland, 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.
