Facebook Opens First Data Center in Prineville, Oregon

          - Open Compute Technology Makes Data Center One of the Most Efficient in US -

Prineville, Oregon (April 15, 2011) – Facebook leaders joined state and local elected officials in Prineville, Oregon today to officially open the company’s first custom-built data center. The Prineville data center features leading energy-efficient technology, which Facebook recently shared with the industry as part of the Open Compute Project. 



“This data center is built for energy efficiency and is a milestone for Facebook,” said Tom Furlong, director of site operations at Facebook. “The new computing capacity will enable us to offer great new social experiences, while setting new standards for environmental responsibility in data center design and operations.”


Furlong also thanked local and state officials for their support of the project. “We went from bare ground to serving users in 15 months,” said Furlong. “That doesn’t happen without the support of city, county and state leaders who have been so helpful in this first phase of the project.”

The Facebook Prineville Data Center, which sits on a 120-acre parcel, is being built in two phases. The first half of the building, approximately 150,000 square feet, is complete. The second half, again approximately 150,000 square feet, will be completed at the end of 2011 and will have servers installed in line with demand.

The Data Center is expected to become LEED gold certified, and includes features such as rainwater reclamation, a solar energy installation for providing electricity to the office areas and reuse of heat created by the servers to heat office space.

In addition, Facebook pioneered several new technologies in the design and operation of the data center, including: New energy efficient server designs; specialized software to optimize server capacity; and a low-energy evaporative cooling system, which make use of the low humidity climate of Central Oregon’s high desert setting to eliminate traditional air conditioners. Overall, the data center uses 38 percent less energy to do the same work as Facebook's exiting facilities.

“I am proud to welcome Facebook as the newest member of Oregon’s innovative technology community,” said Oregon Governor John Kitzhaber. “Facebook will be great addition to the community of Central Oregon and will no doubt serve as a stable economic presence for years to come.”

Over the course of the project, more than 1,300 people have worked on the site – an average of 250 workers a day. When completed, Facebook has committed to hire 35 full-time employees to run and maintain the data center.

“Facebook has brought diversity to the job market at a time when unemployment has ranged from 17-20%,” said Prineville Mayor Betty Roppe. “During the past year Prineville has seen a loss of nearly 1,000 in population according to the US Census.  Facebook’s arrival has opened the market for other business recruitment. Their arrival has given the community a shot of OPTIMISM.”

Facebook has also committed to a $105,000 annual local grant program. To follow the progress of the Facebook Prineville Data Center, go to www.facebook.com/prinevilledatacenter. For more information on the Open Compute Project, go to http://opencompute.org.

Google's Data Liberation Front is an engineering team at Google whose "goal is to make it easier for users to move their data in and out of Google products."The team, which consults with other engineering teams within Google on how to "liberate" Google products, currently supports 27 products. The purpose of the Data Liberation Front is to ensure that data can be migrated from Google once an individual or company stops using their services.


home network

                                            home network

               A home network or home area network (HAN) is a residential local area network (LAN) for communication between digital devices typically deployed in the home, usually a small number of personal computers and accessories, such as printers and mobile computing devices. An important function is the sharing of Internet access, often a broadband service provisioned by fiber-to-the-home or via Cable Internet access, Digital Subscriber Line (DSL) or mobile broadband by Internet service providers (ISPs). If an ISP only provides one IP address, a router including network address translation (NAT), proxy server software and typically a network firewall, allows several computers to share the external IP address. The router function may be assumed by a PC with several network interfaces, but a dedicated router device is more common, often including a wireless accesspoint
, providing WiFi access.

computer network

             A computer network (or data network) is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet.
Network devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as servers and personal computers, as well as networking hardware. Two devices are said to be networked when a process in one device is able to exchange information with a process in another device.
           Computer networks support applications such as access to the World Wide Web, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications. The remainder of this article discusses local area network technologies and classifies them according to the following characteristics: the physical media used to transmit signals, the communications protocols used to organize network traffic, along with the network's size, its topology and its organizational intent.
