LinkedIn has opened a state-of-the-art green data centre in Hillsboro, Oregon. Known internally as LOR1, it has two buildings located on a campus managed by Infomart. The “social networking services” facility uses the ChilledDoor refrigeration system, has access to hydroelectric power and in the future could feed 100% renewable energy.

The green data centre facility offers eight MW of power capacity, cooling a shelf level and a new red topology that is based on 100G connectivity. It has received the Efficient IT (EIT) recognition from the Uptime Institute and has the mission of being a model for future LinkedIn data centres.

LinkedIn offers computer services in the United States (Virginia and Texas) and one in Singapore, but its data centre capacity needs to continue to grow. The Hillsboro facility is served as a test for the Altair Project, a new hyper-scale infrastructure approach.

The campus near Portland has two buildings and four data rooms, which have a cooling system called MotivAir ChilledDoor. A water-cooled door mounts to the back of a rack, with the mission of cooling the air that expel the servers mounted inside. The system adjusts to a variable heat load and an energy distribution of 400 volts.

This cooling system “communicates with air sensors to look at naturally cool temperatures in Oregon, instead of using energy to create cool air,” explains Michael Yamaguchi, director of data centre engineering at LinkedIn. “Incorporating efficient technologies like these allows our operations to run with a PUE of 1.06 during the economising mode,” he added.

Inside the green data centre a single type of red switch, called “Pigeon” has been deployed, which was developed internally by LinkedIn engineers. The complete network has been designed to use the IPv6 protocol from day one. In addition, the facility has access to a hydroelectric power source, and LinkedIn flat that feeds to 100% of renewable energies.

“Our latest data centre is a big step forward, and we are not allowed to deploy hyper-scalable architecture when it is more efficient in how we consume resources,” said Sonu Nayyar, vice president of production and IT operations at LinkedIn. “We seek to improve how we generate energy, with the ultimate goal of achieving our goal of 100% renewable energy,” he added.
