The Office of Management and Budget is setting a new, more aggressive target for data center consolidation in federal agencies. OMB now thinks agencies will close 472 data centers by the end of 2012, up from a previous estimate the office gave in July of 373 closures. By the end of 2015 the goal is 962 centers. Meanwhile, agencies are being told to tackle IT infrastructure in even smaller spaces. OMB’s new definition of data centers will include spaces as small as 100 square feet.
