ABSTRACT:
Client101sends a function to be executed to server102,and at the same time, sends information such as the send destination disk unit, function name, version, etc. The server stores the received function, uses the received information to create function information127,creates function information126that contains access area list124to be sent to disk unit103,and then sends the function and function information126to the disk unit. The disk unit stores the function and function information. When a function execution request is sent from the client to the server, if the server is also sent parameters, it creates additional function information126and sends said function information126together with the function execution request to the disk unit. The disk unit performs the function execution and restricts accesses during execution according to function information126.
