    摘要: Recently, along with the increase in the importance of data protection, there are increasing demands for constructing a computer system capable of protecting data even when widespread disaster occurs. In order to reduce the risk of data loss even when widespread disaster occurs, the present invention computes the risk of data loss for each replication relationship of data (combination of storage subsystems storing the same data), and allocates data so that the risks of losing data of all replication relationships are optimized.

    摘要: Data migration can be preformed between source and target storage subsystems without stopping exchanging data between a host computer and each of the storage subsystems.After a next access path, which should be set instead of a specific access path in an available state among access paths, is set between the host computer and a migration target logical unit via a host port and a target port, the status of the next access path is set to an available state and the status of the specific access path is set to an unavailable state. After the next access path is set to an available state, data is migrated from a migration source logical unit of the source storage subsystem to the migration target logical unit of the target storage subsystem.

    摘要: For a storage apparatus where flash memory disks and hard disks coexist, high-density mounting of flash memory modules is achieved. The storage apparatus includes flash memories and a storage controller. A second storage apparatus including magnetic disks is connected to the storage apparatus. The storage controller can form a storage area using a flash memory or a magnetic disk to create a logical volume. When an input/output request is issued from a host computer, if a storage area is formed with a flash memory, the storage controller directly accesses the flash memory to handle the request. When the storage apparatus defines a storage area formed with a flash memory, the storage apparatus defines the storage area by adding up the capacity of a storage area to be provided for the host computer and a substitute area capacity determined in consideration of restrictions on the number deletions of the flash memory.

    摘要: A storage system has a plurality of flash packages, and a storage controller for receiving a write request from a host and sending a write-data write request based on data conforming to this write request to a write-destination flash package. A virtual capacity, which is larger than the physical capacity of the flash package, is defined in the storage controller. The storage system compresses the write data, and writes the compressed write data to the write-destination flash chip.
