摘要： A first storage system is provided with a first storage device containing an encryption processing unit, and a controller having an encryption processing unit and an access control unit. The access control unit judges whether a writing destination in the case of having processed a write request from an upper-level device is a first logical volume or a second logical volume, and in the case of having judged to be a first logical volume, transmits write data to a first storage device corresponding to the first logical volume without encrypting in the encryption processing unit of the controller, while on the other hand, in the case of having judged the writing destination to be a second logical volume, transmits the write data to a second storage system after having encrypted the target writing data with the encryption processing unit of the controller.

摘要： A storage system 1 including multiple slots for loading a block I/O interface controller, a file I/O interface controller, and any other kinds of interface controllers that are combined freely. The storage system 1 includes a management table that manages fail-over-enabled devices by grouping those devices in accordance with the interface type and the domain to which each device belongs; an information table that directs a fail-over procedure; and fail-over controlling means that takes over the processing of a failed interface controller belonging to a fail-over-enabled group. The fail-over system offers several modalities for monitoring failures, selecting takeover controllers and restoring functionality. Storage system 1 solves conventional problems by providing a system that can mount a plurality of file systems, and that resists multiple failures detected in a fail-over server.

摘要： One code (a compressed redundant code) is created based on a plurality of first redundant codes, each created on the basis of a plurality of data units, and this compressed redundant code is written to a nonvolatile storage area. This compressed redundant code is used to restore either a data element constituting a multiple-failure data, or a first redundant code corresponding to the multiple-failure data, which is stored in an unreadable sub-storage area of a partially failed storage device, and to restore the data element constituting the multiple-failure data which is stored in a sub-storage area of a completely failed storage device, based on the restored either data element or first redundant code, and either another data element constituting the multiple-failure data or the first redundant code corresponding to the multiple-failure data.

摘要： A storage system comprises a primary storage system comprising a primary storage apparatus and a primary control apparatus for controlling the primary storage apparatus; and a secondary storage system comprising a secondary storage apparatus and secondary control apparatus for controlling the secondary storage apparatus. The primary storage apparatus and the secondary storage apparatus are connected to each other via a communication line. The primary storage system sends, to the primary storage apparatus, a data-transfer instruction instructing the primary storage apparatus to transfer predetermined data stored in the primary storage apparatus to the secondary storage system. The primary storage apparatus receives the data-transfer instruction, reads out the predetermined data from the primary storage apparatus, and sends the data via the communication line to the secondary storage apparatus of the secondary storage system.
