    Abstract: A first communication path, which is coupled to a first controller and to a plurality of storage devices (PDEV), and a second communication path, which is coupled to a second controller and to these plurality of PDEVs are provided. Each communication path has a plurality of expanders coupled in series. In order to shorten the time during which the communication path is not used for I/O, either (A) the length of time for which I/O suppression is set for the communication path is shortened, or (B) the overall time it takes for processing other than I/O processing is shortened. In the (A), a determination as to whether or not the coupling between the expanders has been disconnected is made for the I/O-suppressed communication path, and in a case where the result of this determination is negative, a discover process is carried out after releasing the I/O suppression with respect to this communication path. In the (B), the number of command issue times of updating routing control information of the expander is reduced.

    Abstract: Port management information is prepared for managing information related to the status of each of a plurality of ports possessed by a storage system in a unified manner. Change of the status related to any one of a plurality of ports from 'normal' to anomalous is detected. For a subject external device which is using the anomalous path as an I/O path, a 'normal' port is selected, on the basis of the port management information, from one or more ports related to one or more paths which are being used as alternate paths. And information related to this 'normal' port which has been selected is notified to the subject external device. During path changeover, the subject external device selects as an I/O path an alternate path which is related to the 'normal' port specified from the notified information.

    Abstract: An integrated circuit implementing a storage-shelf router (2402, 2403, 2404, 2405) used alone, or in combination with other storage-shelf routers (2402, 2403, 2404, 2405), and in combination with path controller cards, to interconnect the disks within a storage shelf or disk array to a high-bandwidth communications medium, such as an FC arbitrated loop, through which data is exchanged between the individual disk drives of the storage shelf and a disk-array controller. A set of interconnected storage-shelf routers (2402, 2403, 2404, 2405) within a storage shelf can be accessed through a single port of an FC arbitrated loop or other high-bandwidth communications medium. Because, in one implementation, eight storage-shelf routers (2402, 2403, 2404, 2405) can be interconnected within a storage shelf to provide highly available interconnection of sixty-four disk drives within the storage shelf to an FC arbitrated loop via a single FC-arbitrated-loop port, a single FC arbitrated loop including a disk-array controller, may interconnect 8,000 individual disk drives to the disk-array controller within a disk array. The storage-shelf router can serve to translate FC-based communications protocols into one or more communication protocols appropriate to the internal links, providing for use of less expensive, non-FC-compatible disk drives within the storage shelf.
