    Abstract: A management system for managing storage systems, having first correspondence information concerned with correspondence of copy pairs with copy groups as setting of remote copying of data in logical volumes of the storage systems, and second correspondence information concerned with correspondence of physical paths and logical paths between the storage systems with the copy groups, wherein when failure information designating a certain physical path is received, a copy group affected by failure in the certain physical path is specified and displayed by referring to the first correspondence information and the second correspondence information. Consequently, physical paths can be monitored from the viewpoint of remote copying.

    Abstract: The present invention relates to a storage device in which the MR-IOV is applied to an internal network of a storage controller. Data path failover can be executed in the storage device. The internal network of the storage controller is configured to enable the access of a virtual function (VF) "VF 0:0, 1" of each endpoint device (EDO-ED2) from a root port RP0. Likewise, "VF 1:0, 1" of each endpoint device can be accessed from a root port RP1. In a first data path from the RP0 to EDO in a normal state, "VF 0:0, 1" and "MVP 0, 0" are connected by VF mapping. When a failure occurs on the first data path, the MR-PCIM executes the VF migration, whereby in the second data path from the RP1 to EDO, "VF 1:0, 1" and "MVF 0, 0" are connected by VF mapping. As a result, failover to the second data path is realized.

    Abstract: The storage system includes a first storage subsystem having a first logical volume to be accessed by a host computer, and a second storage subsystem connected to the first storage subsystem and having a second logical volume to be mapped to the first logical volume. The first storage subsystem includes a memory having definition information for defining a plurality of logical paths that transfer, to the second logical volume, I/O from the host computer to the first logical volume, and a transfer mode of the I/O to the plurality of logical paths. At least two or more logical paths among the plurality of logical paths are defined as active, and the controller transfers the I/O to the at least two or more logical paths set as active.

    Abstract: An integrated circuit implementing a storage-shelf router (1018) used along, or in combination with other storage-shelf routers (1014), and in combination with path controller cards, to interconnect the disks (1022-1025) within a storage shelf or disk array to a high-bandwidth communications medium through which data is exchanged between the individual disk drives or the storage shelf (1100) and a disk-array controller (1006). In various embodiments, the present invention provides virtual disk formatting by a storage shelf router (1018) and the storage shelf (1100) in which the storage-shelf is included, to external computing entities, such as disk-array controllers (1006) and host computers (1002). By providing virtual disk formatting, a storage-shelf router (1018) can provide to a disk-array controller (1006), and other external computing entities, the disk-formatting convention (4410) expected by the disk-array controller (1006), even though disk drives (1022-1025) and other storage systems that do not conform to the expected formatting conventions may be included in the storage shelf (1100) and interconnected to a disk-array controller (1018) and other external processing entities via an interface provided by a storage-shelf router (1018). Virtual disk formatting, in addition, allows a storage-shelf router to format a disk drive differently from the disk formatting expected by external computing entities, so that the storage-shelf router (1018) can transparently include additional information into disk sectors (4402), such as additional error-correction information.

    Abstract: A storage system has a plurality of control modules (4-0, 4-1, ..., 4-7) for controlling a plurality of storage devices (2-0, 2-1, ... , 2-25), which make mounting easier whilst maintaining a low latency response even if the number of control modules increases. A plurality of storage devices are connected to each control module using back end routers (5-0, 5-1, ..., 5-7), so that redundancy for all the control modules to access all the storage devices is maintained. The control modules and the back end routers are connected by a serial bus, which has a small number of signal lines, the interface being constituted by a back panel (7). This configuration can easily be scaled without mounting problems.
