    摘要: There is provided a computer system comprising a first storage system and a second storage system coupled to the first storage system. The first storage system provides a first storage area. The second storage system provides a second storage area. The second storage system reads and writes the requested data from and to the first storage area associated with the second storage area; specifies the first storage area associated with the second storage area from which the data is to be erased upon reception of a request for erasing the data stored in the second storage area; and transmits the request for erasing the data to the first storage system providing the specified first storage area. The first storage system erases the data stored in the specified first storage area, based on a data erasure condition included in the request for erasing the data.

    摘要: A computer system for preventing data loss that includes: a first storage system having a data storage extent for storing data sent from a host computer; a second storage system having at least one actual replicated data storage extent associated with the data storage extent; an archive appliance having a storage medium associated with the replicated data storage extent in the second storage system; and a data copy unit for controlling copy processing for reading data from the data storage extent in the first storage system and writing the read data to a first actual replicated data storage extent in the second storage system in accordance with specific configuration information. The system also has a connection switching unit for changing the specific configuration information so that a second actual replicated data storage extent, instead of the first actual replicated data storage extent, is associated with the data storage extent.

    摘要: To prevent, when data is erased from a storage system that stores differential of updated data, a large amount of differential data from being created, a storage subsystem provides a first storage area which stores data, and includes a second storage area which stores a replication of data stored in the first storage area. When the data stored in the first storage area is updated, the data is replicated to the second storage area before the data is updated. When a request to erase the data stored in the first storage area is received, replication of unupdated data to the second storage area is suspended and the data stored in the first storage area is erased based on the request to erase the data.

    摘要: A computer system comprises a storage subsystem, a host computer and a management computer, and stores catalogue information containing correspondence between a first volume for data reading or writing and a second volume for storing a copy of the data stored in the first volume. The management computer requests the storage subsystem to erase the data stored in the first volume upon reception of an erasure request of the data stored in the first volume. The storage subsystem erases the data stored in the first volume. The management computer specifies a second volume for storing the copy of the data stored in the first volume based on the catalogue information. The storage subsystem erases data stored in the specified second volume. Thus, security risks are reduced by erasing data regarding the data when the data stored in the volume is erased.

    摘要: There is provided a logical volume management method for storage system. When a logical volume is created on a flash memory drive, a management computer allocates logical volume while flash memory chip border of flash memory drive is taken into account. Specifically, a table for managing a correlation between each parity group and the flash memory chip of the flash memory drive is obtained and the logical volume is allocated in such a manner that a flash memory chip is not shared by a plurality of logical volumes. When complete erasing of logical volume data is performed, the management computer specifies a flash memory chip on which complete data erasing is to be performed, and the storage system completely erases data exclusively on the chip of interest with a use of a function of completely erasing data at a time by chip unit of the flash memory chip (chip erasing).
