Storage apparatus and fan control method and fan control program of storage apparatus
First Claim
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.

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.

6. A fan control method of a storage apparatus provided with 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 module and having a fan, and a chassis storing said physical memory device, said controller modules and said power source modules, said method comprising the steps of:
- monitoring a state of said other controller module and said power source module;
rotating 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; androtating 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. - View Dependent Claims (7)

8. A computer-readable medium including a fan control program for controlling a fan of a storage apparatus provided with 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 module and having a fan, and a chassis storing said physical memory device, said controller modules and said power source modules,
wherein, in order to control the fan of said power source module, a processing portion in said controller module is operated as a fan control portion which monitors a state of 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.
