The ANSI/TIA-942 Site/Facilities Certification (DCCC) indicates that the data center facility under scope has been physically inspected for conformity to the design criteria of the ANSI/TIA-942 standard for the respective Rating level. This physical inspection covers both an assessment of all relevant design documents as well as a physical on-site inspection for each area under the scope of the ANSI/TIA-942 standard.
The ANSI/TIA-942 Site/Facilities Certification is valid for 3 years. By the end of year-1 and year-2, the data center should undergo a surveillance audit. Depending on potential site changes since the official certification audit, the surveillance audit could be based on self-declaration, remote validation or in very rare cases an on-site inspection. By the end of year-3, the data center has to undergo a recertification audit in order to maintain its certification.
EPI is the world's first and so far the only official ANSI/TIA-942 CAB authorised under the official TIA-942 Accreditation Scheme from TIA to provide data center conformity audit services to the ANSI/TIA-942 standard. EPI is also incorporated as a CB (Certification Body).
TIA-942 is the telecommunication infrastructure standard for data centres. This standard however not only cover the telecommunication part but also other important factors which lead to a robust data centre. The data centre will be reviewed for compliance in four categories:
For each of the categories, the data centre will be categorized in four rating levels (Rated 1-4), as well as an overall rating level.
ANSI/TIA-942 describes four rating levels in which data centers can be classified. Below are the high level descriptions of each rating level. Detailed specifications are given in the ANSI/TIA-942 standard.
Note**; The outcome of the Rating levels defined by TIA are similar to the outcome of the Uptime Tier levels i.e. both Rated-3 of TIA and Tier-III of Uptime are both defined as being a Concurrent Maintainable data centre.
