Abstract: A method is provided for optimizing fan speed control of a computer system that includes a fan unit, a temperature sensor, a control unit to control operation of the fan unit, and a disk storage unit. A forbidden range corresponding to a range for a fan speed is determined based on a relationship between fan speed and vibration of the disk storage unit. An optimized fan control table is generated based on a reference table relating to a relationship between ambient temperature and fan speed. The optimized fan control table is generated by making a part of the ambient temperature values in the reference table change to corresponding to a predetermined fan speed not smaller than a fan speed value corresponding to an upper limit of the forbidden range.

Abstract: A server utilizes a BMC to divide a video source signal into original analog and digital component signals, and stores the digital component signal in a set of registers of a duplicator. An ADC converts the original analog component signal into a converted digital component signal, which is stored in another set of registers of the duplicator. A switch set of the duplicator is switched to output a pair of the converted and the original digital component signals. One DAC converts the converted digital component signal into a converted analog component signal, which together with the original digital component signal, serves as a duplicated video signal.
