A Temperature and Humidity Requirements

This topic describes the environmental requirements of the data center where an Oracle Cloud at Customer is being installed.

Table A-1 Oracle Cloud at Customer Temperature and Humidity Requirements

Condition	Operating Requirement	Non-operating Requirement	Optimal Requirement
Temperature	5 to 32 degrees Celsius (59 to 89.6 degrees Fahrenheit)	-40 to 70 degrees Celsius (-40 to 158 degrees Fahrenheit).	For optimal rack cooling, data center temperatures from 21 to 23 degrees Celsius (70 to 74 degrees Fahrenheit).
Relative humidity	10 to 90 percent relative humidity, non-condensing	Up to 93 percent relative humidity.	For optimal data center rack cooling, 45 to 50 percent, non-condensing.
Altitude	3048 meters (10000 feet) maximum	12000 meters (40000 feet).	Ambient temperature is reduced by 1 degree Celsius per 300 m above 900 m altitude above sea level.
