Temperature And Humidity Requirements - Oracle EXADATA X6-2 Installation And Configuration Manual

that the facility administrator or qualified electrical engineer verifies the grounding
method for the building, and performs the grounding work.

1.5 Temperature and Humidity Requirements

Airflow through Oracle Exadata Rack is from front to back. Refer to
Environmental Requirements
The following table lists the temperature, humidity and altitude requirements for
operating and non-operating machines.
Table 1-34
Condition
Temperature
Relative humidity
Altitude
Set conditions to the optimal temperature and humidity ranges to minimize the chance
of downtime due to component failure. Operating Oracle Exadata Rack for extended
periods at or near the operating range limits, or installing it in an environment where it
remains at or near non-operating range limits could significantly increase hardware
component failure.
The ambient temperature range of 21 to 23 degrees Celsius (70 to 74 degrees
Fahrenheit) is optimal for server reliability and operator comfort. Most computer
equipment can operate in a wide temperature range, but near 22 degrees Celsius (72
degrees Fahrenheit) is desirable because it is easier to maintain safe humidity levels.
(page 1-1) for information on cooling and airflow.
Note:
Studies have shown that temperature increases of 10 degrees Celsius (15
degrees Fahrenheit) above 20 degrees Celsius (70 degrees Fahrenheit)
reduce long-term electronics reliability by 50 percent.
Excessive internal temperatures may result in full or partial shut down of
Oracle Exadata Database Machine.
