Humidity levels for a data center are a prime concern for maintaining electrical and computing resources properly as well as ensuring that conditions are optimal for top performance.
Which of the following is the optimal humidity level, as established by ASHRAE?

Answer options

• A. 20 to 40 percent relative humidity
• B. 50 to 75 percent relative humidity
• C. 40 to 60 percent relative humidity
• D. 30 to 50 percent relative humidity
