To resolve the problem that it is difficult to appropriately process successive media data and the like.
In a data storage array apparatus having a controller 1001 to receive instructions to execute data processing and to make two or more data processing devices share the load of executing of the received instructions, the controller 1001 issues the received instructions until the number of the instructions under waiting for execution or under execution by data storage devices 1021-102n has reached up to a predetermined number (1), holds the received instructions without issuing them after the number under waiting for execution or under execution has reached up to the predetermined number (2) and issues successively the instructions which have been held when the remaining number has reached to zero with completion of the executions of the instructions under waiting for execution or under execution, issues instructions which have been held or newly received until the number of instructions under waiting for execution or under execution has reached up to the predetermined number (3).
