What is the overall Rating of this data center when the Rating is based on the ANSI/TIA-942?

A data center scores Rated-3 in mechanical, Rated-4 in electrical, and Rated-2 in architectural.

What is the overall Rating of this data center when the Rating is based on the ANSI/TIA-942?
A . Rated-2 since that is the lowest rating received
B . Rated-4 since that is the highest rating received
C . Rated-4 since electrical is more important than mechanical and architectural
D . Depends on the Rating scored in telecommunications

View Answer

Answer: A

Explanation:

According to ANSI/TIA-942 standards, the overall data center rating is determined by the lowest rating among all evaluated categories. Therefore, if a data center is rated 2 in architectural, despite being rated higher in mechanical and electrical, the overall rating is Rated-2. This approach ensures that all aspects meet a minimum standard and prevents a higher rating if any critical area does not comply.

Detailed Explanation

ANSI/TIA-942 evaluates data centers across several areas, including mechanical, electrical, architectural, and telecommunications. The overall rating reflects the lowest rated category, ensuring that no aspect of the data center’s design or operation falls below the specified level. Thus, in this case, the architectural rating of 2 dictates the final rating, ensuring a comprehensive and balanced assessment of reliability and resilience across all aspects.

EPI Data Center Specialist References:

EPI Data Center Specialist training aligns with ANSI/TIA-942, stating that the final rating must reflect the lowest score to ensure comprehensive reliability across all critical infrastructure categories. This avoids overstating the data center’s resilience and ensures uniform standards across areas.
