Abstract
A hardware-based fan controller for controlling fan modules in a computer system having multiple computer nodes is disclosed. Each of the computer nodes has a service processor. The fan controller includes a slave module that receives fan speed commands from each of the service processors. A fan speed generator is coupled to the slave module and a subset of the fan modules. The fan speed generator receives fan speed commands from the slave module and fan speed outputs from the subset of fan modules. The fan speed generator is configured to output a speed command to each of the fan modules in the subset.
