TIA-942 is the telecommunication infrastructure standard for Data Centres. This standard however does 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:
Further areas to be examined are operational management and other important aspects such as health and safety aspects.
For each of the categories the Data Centre will be categorized in four tier levels (Tier 1 -4) as well as an overall tier level rating.
The audit will provide a report of non-compliances as well as a "EPI Certificate" indicating the level of compliance to the ANSI/TIA-942 standard.
In the following two subsequent years the Data Centre will need to go through a surveillance audit. In the third year a complete (re)certification audit will be conducted to re-establish the Tier classification.
