ANSI/TIA-942 Audit & Certification

ANSI/TIA-942 Design Certification (DCDV)

The design documents of the data centre under scope are reviewed for conformity to the design criteria of the TIA-942 standard for the respective Rating level.

About DCDV

Validate the Design Before Construction

TIA-942 Design Certification (DCDV) confirms that the design documentation for the data centre within scope has been reviewed for conformity against the applicable design requirements of the TIA-942 Standard for the intended Rating level.

The certification focuses on the design stage, helping organisations identify conformity requirements before implementation and construction are completed.

The TIA-942 Design Certification is valid for one year and may be extended where the site is not yet operational.

What Is Assessed?

Four Assessment Categories

Architecture

Site location, building considerations, fire safety, physical security and related architectural requirements.

Electrical

Electrical infrastructure, power distribution, redundancy and supporting systems.

Mechanical

Cooling, environmental systems and associated mechanical infrastructure.

Telecommunications

Telecommunications infrastructure, cabling and connectivity requirements.

ANSI/TIA-942 Rating Levels

Understand the Four Rating Levels

TIA-942 describes four rating levels in which data centres can be classified. Detailed specifications are given in the standard.

Rated-1: Basic Site Infrastructure

A data center which has single capacity components and a single, non-redundant distribution path serving the ICT equipment. It has limited protection against physical events.

Rated-2: Redundant Capacity Component Site Infrastructure

A data center which has redundant capacity components and a single, non-redundant distribution path serving the ICT equipment. It has improved protection against physical events.

Rated-3: Concurrently Maintainable Site Infrastructure

A data center which has multiple independent distribution paths serving the ICT equipment. From a conformity point of view, it is acceptable to have one distribution path serve the ICT equipment with the second distribution path to be on standby for maintenance purposes. However, most data centers use both distribution paths on a continuous basis. The data center is required to be concurrently maintainable meaning that each and every capacity component including elements/components which are part of the distribution path, can be removed/replaced/serviced on a planned basis without disrupting the ICT capabilities to the End-User. It has protection against most physical events.

Rated-4: Fault Tolerant Site Infrastructure

A data center which has multiple independent distribution paths serving the ICT equipment which are all active. The data center allows concurrent maintainability and one (1) fault anywhere in the installation without causing downtime. The data center must be capable to automatically detect a fault, automatically isolate the fault and to automatically continue operation. It has protection against almost all physical events.

Note:

At a high level, ANSI/TIA-942 Rated-3 and Uptime Tier III both address the concept of concurrent maintainability. However, ANSI/TIA-942 and Uptime Tier certifications are separate schemes with their own requirements and assessment criteria.
