A storage apparatus 10 includes a communication control processor 11 that is a processor configured to control communications with a host apparatus 3, and plurality of main processors 12 each configured to perform an I/O process on a storage drive 171 according to an I/O request received from the host apparatus 3. The storage apparatus 10 manages data to be stored or that has been stored in the storage drive 171 in accordance with the CKD format. The storage apparatus 10 distributes the I/O process to the plurality of main processors 12 in units of the data fields on basis of the operation rates of the respective main processors 12, information on a C field, a K field, and a D field that are data fields forming a record of data targeted by the I/O process and managed in CKD format, and an I/O load indicator being a load indicator of the I/O process currently running on each of the main processors. |
