<p>The storage system according to the present invention allows the number of host connections to be increased by connecting a plurality of storage control devices (10, 20) so that commands and data can be directly exchanged between each storage control device. The first storage control device has a plurality of controllers (100A, 100B), and the second storage control device also has a plurality of controllers (200A, 200B). Within each storage control device, controllers are connected by inter-controller communication paths (P1, P2). Also, between storage control devices, controllers belonging to different storage control devices are connected by inter-device communication paths (NPA, NPB). If the subject of processing of a command received by one storage control device is under the control of another storage control device, the command is transferred from the one storage control device to the other storage control device via the inter-device communication path.
