Here's a look inside Facebook's data center in Forest City, North Carolina. The company launched this center in 2010.
Facebook began construction on its second data center in Lulea, Sweden, in March 2014.
Inside Lulea's first data center building, you can see Facebook's "vanity free" approach to design. For instance, there are no plastic bezels in front of its servers — something commonly found in other data centers — to allow those servers to draw in more air.
In the Lulea data center, web server and storage designs use snaps and spring-loaded catches to hold components in place.
Lulea's rapid deployment data center (RDDC) design is all about being lean, which allows Facebook to deploy two data halls in the time it previously took to deploy one, thus reducing the cost of construction.
This is Facebook's data center in Prineville, Oregon, which is the first data center deployed using the company's Open Compute Project designs.
Facebook used 1,560 tons of steel to build its Prineville data center, which is the equivalent of 900 mid-size cars.
Facebook's Prineville data center also uses a lot of wires and cables. In fact, there are 950 miles worth of wires and cables in this data center alone — roughly the distance between Boston and Indianapolis.
The Prineville data center also has a ton of concrete: 14,254 cubic yards, to be exact. Imagine a sidewalk that's 24.3 miles long.
Thanks to Facebook's unique server design, technicians, like this one working in Prineville, don't have to spend time finding the right tools to unscrew multiple components every time they need to replace a failed component.
Facebook's rapid data center deployment structure is similar to assembling a car: The structural frame is built before all of the components, which are attached on an assembly line in a factory. The entire structure is driven to the building site on a truck.
With the efficiency gains afforded by the unique server designs, Facebook has reduced the average repair time to swap parts by more than 50%.
Here you can see technicians delivering server racks to Lulea's building one, the company's first data center building.
As a result of these unique data centers, Facebook can handle the billions of daily "Likes" and photos, as well as the trillions of messages that have been sent since Facebook was founded over a decade ago.
