Abstract:
1. A storage apparatus comprising: two or more controller modules controlling a data transfer with a host machine and a data transfer with a physical memory device; two or more power source modules supplying a power to said physical memory device and said controller modules and having a fan; and a chassis storing said physical memory device, said controller modules and said power source modules, wherein a first controller module of said two or more controller modules monitors a state of the other controller module and said power source module, rotates the fan of said power source module corresponding to the module in which a failure is detected at a first speed which is higher than a normal rotational speed when the failure of said other controller module and said power source module is detected, and rotates the fan rotated at said first speed at a second speed which is higher than said first speed when it is detected that said module in which the failure is detected is detached.
