Fan management system
A fan management system includes a chassis housing a storage fan system, a storage system cooled by the storage fan system, computing fan subsystems, and computing devices cooled by respective ones of the computing fan subsystems. Each of the computing devices detects a multi-computing-device configuration that includes the computing devices and, in response, determines a computing device chassis location for that computing device. Each computing device then receives fan inventory information that describes the storage fan system and the computing fan subsystems, distinguishes between the storage fan system and the computing fan subsystems based on the fan inventory information, identifies the computing fan subsystem that is configured to cool that computing device based on the computing device chassis location for that computing device, manages the computing fan subsystem that is configured to cool that computing device, and ignores the others of the computing fan subsystems.
