What is the minimum required Tier level for a data center under the ANSI/TIA-

  1. Tier I

  2. Tier II

  3. Tier III


    anation: The ANSI/TIA-942 standard defines four Tier levels for data ers, with Tier I being the minimum requirement. Tier I data centers ha e path for power and cooling distribution, with no redundant compone er Tier levels (II, III, IV) introduce more redundancy and fault toleran res. Therefore, the correct minimum required Tier level under the I/TIA-942 standard is Tier I.
