    摘要: A computer system in which an encryption-decryption process performed by one encryption-decryption module can be moved to another without stopping the process for a read/write request from a host computer. The computer system has a host computer, and a storage system for storing encrypted data. The storage system provides a storage area for accepting access from the host computer. In performing a process for changing the data encrypted and stored by the destination source, the move destination encrypts the data decrypted by the move source which further encrypts and stores the data encrypted by the move destination, and after all data is stored, the move source decrypts and stores the further encrypted data.

    摘要: A copy source storage controller received write data added with a time and issued from a host computer transfers the write data with the time to a copy destination storage controller. If there are a plurality of copy destination storage controllers, a representative copy destination storage controller compares times of write data copied to the plurality of copy destination storage controllers, and writes the write data in copy destination logical volumes in the sequential order of time. The representative copy destination storage controller judges that integrity of the write data is established, if a communication procedure is established with the copy destination storage controller and if the statuses of the copy source/destination logical volumes are coincident. In remote copy which guarantees integrity of write data and traverses a plurality of storage controllers, it is possible to judge at an optional time point whether integrity of write data can be guaranteed.

    摘要: A data storage or management method is provided which allows both a content object-based access and a file-based access. A first request for storing a content object in accordance with the processing of an application program executed in a host is sent to an object archive control functionality executed in the host, an intermediate server, or a storage apparatus. The object archive control functionality generates an object identifier corresponding to the content object received in response to the first request, a directory name corresponding to the object identifier, and a plurality of file names corresponding to a plurality of fields contained in the content object. The storage apparatus stores a directory having the directory name and the plurality of files having the plurality of file names in accordance with the second request.

    摘要: When there is a change in a group of volumes managed by a host computer, data duplication processing is immediately carried out against the changed volume. The host computer includes a volume-managing portion, a data duplication-controlling portion which executes the data duplication of data stored in a volume in a main data center, and a data duplication storing portion which stores data necessary for the data duplication. The data duplication-controlling portion compares data held by the volume-managing portion with the data in the data duplication storing portion, and updates the data in the data duplication storing portion based on the data held by the volume-managing portion.

    摘要: A computer system including a first storage system connected to a first host computer, a second storage system connected to a second host computer and a third storage system connected to the first and second storage systems. The second storage system sets transfer setting before an occurrence of a failure, the transfer setting being provided with a dedicated storage area to be used for transferring data to the third storage system by asynchronous copy in response to a failure at the first host computer. Before the start of data transfer between the second storage system and third storage system to be executed after an occurrence of the failure, the second storage system checks the dedicated storage area, data transfer line and transfer setting information, and if an abnormal state is detected, this abnormal state is reported to the host computer as information attached to the transfer setting.
