Along with humidity, temperature is crucial to a data center for optimal operations and protection of equipment. Which of the following is the optimal temperature range as set by ASHRAE?

The correct answer is C. 64.4 to 80.6 degrees Fahrenheit (18 to 27 degrees Celsius). ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) publishes thermal guidelines for data centers. Their recommended temperature range for data center environments is 18°C to 27°C (64.4°F to 80.6°F). Temperatures too low waste energy on…

Explanation

ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) publishes thermal guidelines for data centers. Their recommended temperature range for data center environments is 18°C to 27°C (64.4°F to 80.6°F). Temperatures too low waste energy on unnecessary cooling, while temperatures too high risk overheating equipment and causing hardware failures. This range balances equipment protection with energy efficiency and is the standard referenced in cloud and data center security certifications.
