Abstract
A control system for a plurality of hard disks includes a chip unit, a first storage unit, and a second storage unit. The chip unit includes a first, second, and third GPIO pin and a firmware. The first storage unit is coupled to the chip unit and a plurality of hard disks. The second storage unit is coupled to the chip unit and a plurality of hard disks. When the first GPIO of the chip unit receives a power on signal, the firmware carries out a staggered spin-up function, the second GPIO of the chip unit outputs a first signal to the first storage unit, the hard disks of the first storage unit execute spin up, after a preset delay time, the third GPIO of the chip unit outputs a second signal to the second storage unit, and the hard disks of the second storage unit execute spin up.
