Abstract
Provided is a storage apparatus for providing a logical storage area as a data storage area to an external apparatus, comprising: a physical storage medium for creating the logical storage area; first and second storage control modules each of which is communicatively coupled to the physical storage medium to control data input/output processing between the external apparatus and the logical storage area; and first and second power supply modules each of which supplies power to the physical storage medium and the first and second storage control modules and includes a blower for generating a cooling airflow to cool down the physical storage medium and the first and second storage control modules, wherein the blower of the first power supply module generates a first cooling airflow which flows through the physical storage medium, the first storage control module, and the first power supply module, the blower of the second power supply module generates a second cooling airflow which flows through the physical storage medium, the second storage control module, and the second power supply module, and in a case where the first power supply module is removed from the storage apparatus, the blower of the second power supply module generates a third cooling airflow which flows through the physical storage medium, the first storage control module, and the second power supply module as a replacement for the first cooling airflow.
