Metric Target Values

OMB will measure agency progress for this initiative using the following optimization, cost savings, and closure metrics and goals on a quarterly basis, by way of agencies’ quarterly data center inventory submissions. These optimization, cost-savings, and closure metrics and goals apply to all data centers at agency facilities.

Goal 1: Optimization

The following optimization metrics are listed in order of priority. Agencies shall achieve and maintain all listed target values by the end of fiscal year 2018:

Table 1- Government-wide Optimization Targets for Tiered Data Centers 24

Metric Definition Calculation FYE 2018 Target Value
Energy Metering (%) Percent of total gross floor area (GFA) 25, in an agency’s tiered data center inventory, located in tiered data centers that have power metering. Total GFA of Energy, Metered Data Centers / Total GFA of All,Tiered Data Centers 100%
Power Usage Effectiveness (PUE) 26 (Ratio) Proportion of total data center,energy used by IT equipment. Total energy Used / Total IT Equiptment Energy Used ≤ 1.5 (≤ 1.4 for new data,centers)
Virtualization (Ratio) Ratio of operating systems (OS) to,physical servers. (Total Server Count + Total Virtual OS) / Total Physical Servers ≥ 4
Server Utilization &,Automated Monitoring (%) Percent of time busy (measured as 1 –,percent of time spent idle), measured directly by continuous, automated,monitoring software,27 discounted by the,fraction of data centers fully equipped with automated monitoring. Average Server Utilization * Percent of, Data Centers Fully Equipped with Automated, Monitoring ≥ 65%
Facility Utilization (%) Portion of total gross floor area in, tiered data centers that is actively utilized for racks that contain IT, equipment. (Total Active Rack Count28 * 30 Sq Ft)/ Total Gross Floor Area ≥ 80%

Only the Server Utilization & Automated Monitoring optimization metric shall apply to non-tiered data centers. High-performance computing (HPC) nodes can be excluded from calculations of Virtualization and Server Utilization & Automated Monitoring.

Goal 2: Cost Savings and Avoidance

Agencies shall, by the end of fiscal year 2018, reduce Government-wide annual costs attributable to physical data centers by at least 25%, relative to the fiscal year 2016 IT Infrastructure Spending data submitted to the Federal IT Dashboard29. Agencies shall collectively achieve the following amounts of savings (combined cost savings and cost avoidance)30 in each of fiscal years 2016, 2017, and 2018:

Table 2. Cost Savings Target-

FY2014 Physical Data Center Spending Total Savings Targeted by FYE 2018
$5.4 billion $2.7 billion

Only the Server Utilization & Automated Monitoring optimization metric shall apply to non-tiered data centers. High-performance computing (HPC) nodes can be excluded from calculations of Virtualization and Server Utilization & Automated Monitoring.

Goal 3: Closed Data Centers

In all cases, the term “closed” for data centers shall refer exclusively to tiered or non-tiered data centers that: a) no longer consume power for physical servers; or b) no longer house physical servers (whether in a production, test, stage, development, or any other environment)31.

Based on the number of data centers designated by the agencies as already undergoing some part of the closure process, agencies currently plan to close 22% of tiered data centers and 50% of non-tiered, non-cloud data centers, for a total of 44% of all Federal data centers. OMB’s goal for the DCOI is informed by, but exceeds, agencies’ existing closure plans.

By the end of fiscal year 2018, agencies shall close at least 25% of tiered data centers government-wide, excluding those approved as inter-agency shared services provider data centers. Furthermore, agencies must close at least 60% of non-tiered data centers government-wide.32 This target will result in the closure of approximately 52% of the overall Federal data center inventory and a reduction of approximately 31% 33 in the gross floor area occupied by data centers government-wide. Agencies shall prioritize the closure of data centers that are unable to meet applicable PUE optimization targets and/or pose management or security challenges due to age.

In the long term, all agencies should continually strive to close all non-tiered data centers. Server rooms and closets pose security risks and management challenges and are an inefficient use of resources. As such, although at least 60% of non-tiered data centers are required to be closed before the end of fiscal year 2018, OMB expects that agencies will consider all such facilities as temporary and work to close them.

Within 30 days after publication of this document, OMB OFCIO will share with each agency its individual goal for data center closures, specifying the respective number of tiered and non-tiered data centers the agency must close. OMB may exclude from these agency-specific targets data centers that are physically inseparable from non-IT hardware (e.g. simulation and modeling devices, sensors, etc.) and that perform a specific, non-standard set of tasks (e.g. do not provide general purpose computing or storage services to Federal facilities).


Footnotes:

24 While agencies should strive to achieve each applicable optimization target for each data center, only PUE targets will be calculated on a per-data center basis. All other targets will be calculated at the agency inventory-level.

25 “Total gross floor area” is defined as total square footage available for IT equipment and includes all associated corridors, walkways, and air circulation requirements. This does not include office space, mechanical rooms, or storage areas.

26 PUE shall be calculated by OMB based on quarterly average IT and facility electricity usage data.

27 Server utilization shall be collected continuously and reported as a quarterly average.

28 “Active” racks are those that have IT equipment consuming electricity.

29 Benchmarked against the sum of all non-cloud data center costs (including data center labor, software, hardware, electricity, and facility) found in physical data center fields of the IT Inventory Summary Table of the IT Dashboard.

30 Estimated reduction in gross floor area of data centers is approximate and has been based on the average size, in square feet, of the data centers of each type to be closed.

31 Excludes print servers.

32 The baseline number of data centers is based on the agencies’ August 31, 2015, data center inventory submissions, as collected by OMB OFCIO through the Integrated Data Collection.

33 Estimated reduction in gross floor area of data centers is approximate and has been based on the average size, in square feet, of the data centers of each type to be closed.
