Abstract
One object of the disclosure is to reduce a capacity of cached data, reduce a transfer volume, or reduce a management cost. One aspect of the disclosure is a computer system including a storage control unit and a storage apparatus. The storage control unit receives a notification of information on an operation mode determined by an operation mode determination unit based on processing executed by a processing execution unit. When an access request is received via a virtual volume from the processing execution unit in a case where target data is not stored in a cache volume, the storage control unit executes an access to a real volume. The storage control unit controls the cache volume based on the information on the operation mode.
