For technology companies like Facebook and Google, the data center should be at a military level of secrecy, with most of the company's internal staff not even going to get in.
Recently, however, Facebook has invited some reporters to visit its Prineville data center in Oregon State.
(Prineville is located in northwestern United States.) Figure from: Google)
The Prineville Data Center is the first data center on Facebook. It currently has three large buildings, the smallest of which covers an area of 350,000 square meters; The latest one is still under construction and covers an area of 450,000 square meters. Each of the three buildings is enough to hold a rocket launcher, and there is plenty of room to spare.
Let's look through the pictures.
Slightly high-profile signage
Other companies don't usually put a sign next to their own data center, but Facebook doesn't. This is the entrance mark that it sets next to the Prineville complex.
Water and solar energy
Facebook chose to set up a data center in a deserted Oregon State to take advantage of the cool air here, instead of the server cooling function. In the picture we can also see that there is a huge reservoir for cooling when the weather gets hotter.
On the electricity side, the data center consumes most of the electricity that the local grid supplies, but Facebook also uses solar power to generate electricity.
Spare equipment
If there is a problem with the data center, the technician will take out some spare equipment from the room. Each of them has been labeled with barcodes, and has been kept in custody.
Community
In a small town like Prineville, Facebook is a more important employer. Facebook has helped boost local power and water systems, so it has been welcomed by local people.
Data of the "morgue"
This room is not even available to most of the data center staff because it is dedicated to disk data cleanup. In this room, Facebook deletes the data from the disk and then puts the disk back into use or destroys it directly.
Snacks
Yes, even if the feeling of cold place, there will be snacks appear, and seemingly a lot.
Ubiquitous servers
Facebook does not use air conditioning to adjust the temperature, so in the server room, not so noisy, the temperature is more comfortable. The server on the left side of the picture stores the user's account information.
So theoretically, if you're logged into Facebook today, chances are you're already connected to the server in the picture.
or the server
These servers are primarily responsible for hosting Facebook's social network data.
Aisle
There are about 24 server shelves on each side of the aisle.
Server Details 1
The following diagram provides a clearer view of the server details. The blue light that appears here is emitted by LED lights.
Server Details 2
Look, there's nothing to explain.
Heat discharge
In order to cool the CPU, the cold wind needs to be pumped from the outside, and then the cold wind is drawn to the corridor in the diagram. When the cold wind gets hot, it will be discharged. Unlike other directions in this building, these aisles are noisy and very hot.
Fan
This picture shows the server's fan.
Big Sur
The data center placed Facebook's Big Sur AI server. Each one is equipped with 8 Nvidia high-end chips. These servers look a bit thicker than the rest of the Facebook servers.

Big Sur Detail Figure 2
As you can see, each Big Sur server has two CPUs.
Cooling system
The second floor of the server room is the cooling system. The right side of the picture is where the outside air comes in. But before they come in, they have to pass through a screen to filter out the dust from the air.
Cooling system Details
When the air is filtered, it is necessary to enter a gas cooling system.
Fan
The fan in the figure can inhale the air into the server room.
Large fan
When the cold air completes their mission, it will be drawn out by the outside Wind fan.
Building No. 4th
In this photo, there is building No. 4th. This building is basically contributed to the "Frozen memory". The so-called "Frozen Memory" refers to the old users posted on Facebook for some long time photos, articles, videos and other data, the user basically will not go to see. After all, Facebook can't delete them, so move the data to building 4th.
Therefore, the servers in building 4th are basically "asleep" unless they receive data requests from users.
Construction of Building No. 3rd
Building No. 3rd is still under construction.
Backup generators
If there is a power failure, the giant generators in this picture can play a role.
Frozen memories.
This is the server used to store "Frozen memory". There are 32 servers on each shelf that can store 2PB of data. (1PB=1024TB,1TB=1024GB)

Equipment test Lab
In addition to storing "Frozen memories", building 4th was also used as a mobile device testing lab for Facebook. There are about 60 shelves in the picture, with 32 phones on each shelf. These phones are designed to test new versions of Facebook apps.
Facebook icons
Facebook logo is rarely seen in the data center, but it's not.
The Last Egg
The so-called egg is Apple's data center in Prinevile. Unlike Facebook, Apple does not set any logos around it.
