Data Center Optimization: Agencies Report Progress and Billions Saved, but OMB Needs to Improve Its Utilization Guidance, Report to Congressional Committees [open pdf - 3MB]
From the Highlights: "In December 2014, Congress enacted federal IT [information technology] acquisition reform legislation known as FITARA [Federal Information Technology Acquisition Reform Act], which included provisions related to ongoing federal data center consolidation efforts. OMB's [Office of Management and Budget] federal Chief Information Officer launched DCOI [Data Center Optimization Initiative] to build on prior data center consolidation efforts and improve federal data centers' performance. FITARA included a provision for GAO [Government Accountability Office] to annually review agencies' data center inventories and strategies. This report addresses (1) agencies' progress on data center closures and the related savings that have been achieved, and agencies' plans for future closures and savings; (2) agencies' progress against OMB's data center optimization targets; and (3) the effectiveness of OMB's metric for server utilization and how the agencies are implementing it. To do so, GAO reviewed the 24 DCOI agencies' data center inventories as of August 2020, their reported cost savings documentation and data center optimization strategic plans, and OMB's revised utilization metric."
