Abstract
Methods, systems and devices are provided for configuring an airflow cooling system shared by a plurality of IHSs (Information Handling Systems). An initial fan speed is set by a chassis manager that controls airflow cooling shared by the IHSs. The chassis manager broadcasts the initial fan speed to the plurality of IHSs. Each IHS receives the initial fan speed broadcast and determines its own fan speed requirements. If an IHS requires a fan speed greater than the initial fan speed, the IHS broadcasts a fan speed request. Each IHS continues to monitor fan speed broadcasts and broadcasts a request if its determined fan speed is greater than the most recent broadcast. The IHS that broadcasts the greatest fan speed request is designated as the dominant IHS. The chassis manager sets the airflow cooling system fan speed based on the fan speed requests broadcast by the dominant IHS.
