Department of Defense Implementation of the Federal Data Center Consolidation Initiative: Implications for Federal Information Technology Reform Management

The Department of Defense DOD is the single largest energy consumer in the nation. As the largest owner of federal data centers, with 772, the DOD has more than twice as many centers as any other agency. By consolidating some of its data centers, DOD could have a significant positive impact on energy savings for the federal government. DOD has instituted a number of policy directives, as have all federal agencies, that influence energy use in its data centers. Data centers are facilities buildings or parts of buildings used to store, manage, and disseminate electronic information for a computer network. They house servers, which are computers used to perform network-management functions such as data storage and processing, and communications equipment and devices to connect the servers with the network. Data centers usually draw their power from the electric grid, but they may also contain specialized power conversion and backup equipment to maintain reliable power. Power consumption varies greatly among data centers but is typically many times higher than for other kinds of buildings. Within the context of the FDCCI, DOD s efforts are intended to address concerns about rising energy demands and costs of data centers, associated increases in carbon emissions, expanding real-estate footprints of data centers, and rising real-estate costs. According to DOD, the Department plans to reduce the number of its data centers by about 30 by 2013, and the number of servers by 25. DOD intends to use savings generated from consolidation to pay the consolidation costs. DOD also plans to use cloud computing as part of its savings effort.
