Lulea, Sweden is home to Facebook’s newest data center and is already handling live traffic from across the world. The center runs on locally generated hydro-electric energy along with the icy Nordic air to power and cool the masses of servers while the excess heat generated is harnessed to keep the offices warm. All equipment is also 100% renewable. .
The upper level of Facebook’s data center serves as a huge cooling system, with fresh air entering the building through louvers and then passing through a series of chambers that filter and cool the air, which then enters the server area on the lower floor. This fan wall helps maintain pressure to guide the air through filters.
What happens to the warm air that comes out of the back of Facebook’s servers? It rises into a plenum above the data hall, and then into this chamber at the end of the “penthouse” level, where it will typically be vented to the outside through the row of fans at left. On cold days, the exhaust heat can be recirculated and mixed with outside air to adjust its temperature before entering the data hall.
Here’s one of the data halls in Lulea, with rows of server racks on either side of a central corridor. Cool air from the facility’s upper-level “penthouse” cooling system enters the room above this center aisle, and is diffused by the screens seen near the top of the photo, which help the air spread to the end of the rows.
Servers.Lots of servers. Here’s a look at the racks inside the Lulea facility, with network switches at the top of the rack, servers filling the bulk of the rack, and storage at the bottom.
