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.

Abstract: A system and method for logging state data from a power system control device on a computer system is disclosed. The computer system includes a power system supplying power to the computer system. The power system has a power-up sequence having a plurality of stages. The power system control device is coupled to the power system. The power system control device includes a finite state machine circuit having states corresponding to the stages of the power-up sequence. The control device also has a write controller, a storage buffer, and a communication interface. The write controller writes the state of the finite state machine circuit in the storage buffer. An external controller is coupled to the communication interface and is operable to read the stored state data.
