Environmental data centers have been successfully acquiring, disseminating, and archiving data for decades. However, the increasing volume and number of data sets, coupled with greater demands from more diverse users, are making it difficult for data centers to maintain the record of environmental change. This workshop report focuses on technological approaches that could enhance the ability of environmental data centers to deal with these challenges, and improve the ability of users to find and use information held in data centers. Among the major findings are that data centers should rely more on off-the-shelf technology-including software and commonly available hardware-and should shift from tape to disk as the primary storage medium. Such technological improvements will help solve many data management problems, although data centers and their host agencies will have to continue to invest in the scientific and human elements of data center operations.

Over the last 15 years, the federal government's increasing demand for IT has led to a dramatic rise in the number of federal data centers and a corresponding increase in operational costs. According to OMB, the federal government had 432 data centers in 1998 and more than 1,100 in 2009. Operating such a large number of centers is a significant cost to the federal government, including costs for hardware, software, real estate, and cooling. For example, according to the Environmental Protection Agency, the electricity cost to operate federal servers and data centers across the government is about $450 million annually. According to the Department of Energy, data center spaces can consume 100 to 200 times more electricity than a standard office space. According to OMB, reported server utilization rates as low as 5 percent and limited reuse of data centers within or across agencies lend further credence to the need to restructure federal data center operations to improve efficiency and reduce costs.
