ABSTRACT:
This invention provides a storage apparatus for inhibiting temperature increase in a chassis caused when a cooling fan or a module is detached and replaced due to the failure thereof. The storage apparatus comprises a controller for controlling data transfer, a power source supplying a power to a hard disk drive and the controller and having a fan, and a base chassis. The controller monitors a state of other controller and the power source, rotates the fan of the power source corresponding to the module in which a failure is detected at a first high speed higher than a normal rotational speed when detecting the failure of the other controller or the power source, and rotates the fan rotated at the first high speed at a second high speed higher than the first high speed when detecting the detachment of the module in which the failure is detected.
