Optimization Metrics

The Data Center Optimization Initiative (DCOI) provides a framework to help agencies meet Government-wide data center consolidation and optimization requirements. It outlines four major optimization metrics in which agencies are expected to show continuous improvement. Agencies must achieve and maintain all listed target values outlined in the DCOI memorandum by the end of fiscal year 2020, as described below:

Energy Metering

Energy-use data can help you track long-term trends, benchmark progress and performance, perform diagnostics, and alert data center operators to impending or ongoing system failures. Per M-19-19, Agencies are expected to have advanced energy metering and sub-metering, sufficient to accurately estimate Power Usage Effectiveness (PUE), for all remaining data centers over 100 kW that they are planning to keep open.

Virtualization

Data center virtualization includes virtualizing physical servers in a data center facility, as well as storage, networks and other infrastructure devices and equipment. The DCOI metric is the number of servers and mainframes that are currently serving as hosts for virtualized or containerized systems in an agency-managed data center.

Server Utilization/Automation

Server utilization is the percentage of time during which the server is busy processing jobs during a simulation. The DCOI metric is measured by the number of underutilized production servers in each data center, as determined by agencies with consideration for CPU usage and storage space.

Availability

Availability is reported in DCOI in terms of the planned hours of availability for each data center, as well as any unplanned outages for that data center over the reporting period, also measured in hours.
