A storage system has a plurality of control modules for controlling a plurality of storage devices, which make mounting easier with maintaining low latency response even if the number of control modules increases. A plurality of storage devices are connected to the second interface of each control module using back end routers, so that redundancy for all the control modules to access all the storage devices is maintained. Also the control modules and the first switch units are connected by a serial bus, which has a small number of signals, constituting the interface by using the back panel. By this, mounting on the printed circuit board becomes possible.
