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? 

Answer options:

A. 69.8 to 86.0 degrees Fahrenheit (21 to 30 degrees Celsius)
B. 51.8 to 66.2 degrees Fahrenheit (11 to 19 degrees Celsius)
C. 64.4 to 80.6 degrees Fahrenheit (18 to 27 degrees Celsius)
D. 44.6 to 60.8 degrees Fahrenheit (7 to 16 degrees Celsius)

C

The American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) recommends 64.4 to 80.6 degrees Fahrenheit (or 18 to 27 degrees Celsius) as the optimal temperature range for data centers. None of these options is the recommendation from ASHRAE.
