    摘要： The present invention provides techniques, including a method and system, for transferring data between computer systems, for example, a mainframe and a Personal Computer (PC), having storage systems of different formats, efficiently. One embodiment provides a method for transferring data from a first system, having a first processor and a first memory, using a first format to a second system, having a second processor and a second memory, using a second format. The method includes a first system receiving data of a first format from a first disk unit; processing the data of the first format into transformed data, where the transformed data is the data transformed into the second format; storing the transformed data in the first memory; and sending the transformed data from the first memory to the second system responsive to a request from the second system.

    摘要： A data sharing method and system between information processing systems which enable an information processing system to share data in an internal disk unit possessed by another information processing system. A disk control unit within the other information processing system having an external disk unit or an external disk unit includes a disk data sharing mechanism for creating a read/write request to the internal or external disk unit from a command equivalent to a read/write request to a data in a conventional disk subsystem. This mechanism emulates a CCW command to access data in the disk unit.

    摘要： A storage system includes plural storage apparatuses storing data, and a storage controller which transmits and receives data between an external computer and the plural storage apparatuses, and further controls the plural storage apparatuses. Logical devices each representing a logical storage area are defined on the storage apparatuses. When one logical device is in a state of allocation to the external computer and stores data used by the external computer, and the logical device is deallocated from the external computer, the storage controller performs a processing such as erasing data from the logical device to be deallocated. The processing is performed according to the logical device being deallocated.

    摘要： Data states of storage apparatuses are managed. When a storage apparatus is allocated from a storage pool to a computer, management information written in the storage apparatus is erased if the data state of the storage apparatus is unknown. When the storage apparatus becomes unnecessary and is restored to the storage pool, the management information is also erased. Further, when the storage apparatus is allocated to the computer, a level of confidentiality is set. When the storage apparatus is restored to the storage pool, data in the storage apparatus is automatically erased according to the set level of confidentiality.

    摘要： In a computer system that includes a first computer, a second computer, a first storage apparatus storing data in a fixed-length block format used by the second computer, and a backup apparatus connected to the first computer and storing data in a variable-length block format, the present invention provides a backup method for backing up data stored in the first storage apparatus to the backup apparatus. The first computer sends the second computer a request to read data in the fixed-length block format. In response to this request, the second computer reads the fixed-length block format data from the first storage apparatus and transfers this data to the first computer. The first computer converts the transferred fixed-length block format data into variable-length block format data. The converted variable-length block format data is stored in the backup apparatus.

    摘要： The storage system is coupled to a computer and includes a plurality of physical storages being used to configure a first logical storage and a second logical storage, a control unit receiving a read request and a write request from the computer; and a cache memory storing data which is sent to the computer. The control unit determines whether a request from the computer is a write request or a read request. If it is a read request, the control unit reads data from the cache memory or at least one of the plurality of physical storages based on the read request. If it is a write request, the control unit determines whether destination of the write request is the first logical storage.
