Abstract
A storage apparatus includes: a storage drive providing a physical storage area for creating a logical storage area used by an external apparatus; a storage controller including a plurality of central processing units (CPUs) executing data write processing from the external apparatus to the storage drive, and data read processing from the storage drive; a plurality of cooling fans cooling the storage drive; a temperature sensor detecting a temperature of air introduced or discharged by the cooling fans; and a revolving speed sensor detecting a revolving speed of each cooling fan. Any of the CPUs executes operation control processing in which, through a data network path to the storage drive for the data write and read processing, measurement values of the temperature and revolving speed sensors are acquired and a revolving speed setup value of the fans is calculated and is transmitted to the cooling fans.
