Nerval's Lobster writes with news that U.S. federal agencies are falling behind in their efforts to consolidate government data centers. Current plans call for a savings of $2.4 billion and the closing of over a thousand data centers, but 17 of 24 agencies still haven't provided details on their IT infrastructure and usage. A new report from the Government Accountability Office highlights the problems with this consolidation effort. "Data centers represent a significant cost to the federal government. Electricity to operate federal servers and data centers costs around $450 million a year, according to an EPA estimate cited in the report. Moreover, federal agencies reported limited reuse of data centers, along with server utilization rates dipping as low as 5 percent. The GAO report features agencies claiming several challenges on the way to data-center consolidation. These included accepting cultural change as part of the consolidation; funding the consolidation and identifying the resulting cost savings; operational challenges including procurement and resource constraints; and difficulties in planning a migration strategy."
