Abstract

In one or more embodiments, one or more systems, methods, and/or processes may receive ambient temperature limits of information handling systems; may receive ambient temperatures associated with the information handling systems; may determine ambient temperature margins based at least on the ambient temperature limits and the ambient temperatures; may determine that each ambient temperature margin of the ambient temperature margins is above an ambient temperature margin threshold of ambient temperature margin thresholds associated with the information handling systems; in response to determining that each ambient temperature margin of the ambient temperature margins is above the ambient temperature margin threshold of the ambient temperature margin thresholds associated with the information handling systems, may determine that a supply air temperature of the computer room is to be increased; and may reduce a duty cycle of a cooling system of a computer room air handler associated with the computer room.
