Storage apparatus and control method therefor
First Claim
1. A disk array device comprising:
- a controller;
a plurality of storage devices including a first storage device and a second storage device, which store data sent from said controller; and
a plurality of cooling devices including a first cooling device which cools said first storage device and a second cooling device which cools said second storage device,wherein said controller controls an output level of said first cooling device to be set to a first output level when said first storage device is in a first operating state where said first device is ready to store data sent from said controller; and
controls an output level of said second cooling device to be set to a second output level which is lower than said first output level when said second storage device is in a second operating state where said second storage device is ready to shift to said first operating state for storing data sent from said controller according to a command sent from said controller.
