PROBLEM TO BE SOLVED: To improve performance and reliability of a storage controller especially for offering high performance making the best use of high-speed data transfer brought by a fiber channel. SOLUTION: A loop 133 is a shared loop transmission path having a fiber channel interface. HIFC 103, 104, and 105 are connected to host computers 100, 101, and 102 different in interface respectively and provided with a conversion function with the fiber channel interface if necessary. Control processors 114-117 are shared between the HIFC 103-105. The control processors 114-117 refer to FCAL management information 113 respectively, incorporate a frame having a set address from frames flowing through the loop 133, and process an input/output request within a set LUN area.
