"Classification of Physical Data Centers
For the purposes of this memorandum, rooms with at least one server, providing services (whether in a production, test, stage, development, or any other environment), are considered data centers. However, rooms containing only routing equipment, switches, security devices (such as firewalls), or other telecommunications components shall not be considered data centers. Agencies shall perform a comprehensive review of their data center inventories and continue to maintain complete and updated data center inventories. This comprehensive review shall be completed by February 28, 2016, to align with the Integrated Data Collection (IDC) process.
Data centers shall be categorized into two groups: tiered(14) data centers and non-tiered data centers. Tiered data centers are defined as those that utilize each of the following:
All other data centers shall be considered non-tiered data centers.(15) Private sector-provided cloud services are not considered data centers for the purposes of this memorandum.
Agencies shall self-classify data centers as either tiered or non-tiered data centers based on the above criteria; however, any data center previously reported to OMB as a Tier 1-4 data center shall be automatically categorized as a tiered data center.
Under this memorandum, OMB sets closure and optimization targets that are applicable to each type of data center. Additionally, the terms "core" and "non-core" will no longer be used as the categorical benchmarks for OMB oversight."
