    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.

    摘要: For a storage apparatus in which flash memory disks and hard disks coexist, high-density mounting of flash memory modules is achieved. A storage apparatus in accordance with the present invention includes flash memories and a storage controller. A second storage apparatus including magnetic disks is connected to the storage apparatus. For creation of a logical volume, the storage controller can form a storage area using a flash memory or a magnetic disk. 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 input/output 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 imposed on the number of times of deletion of the flash memory.

    摘要: A second storage maps a migration source volume to a virtual volume of a migration destination volume according to storage virtualization technology. A host system including a host switches an access path from an access path to the migration source volume to an access path to the migration destination volume. The second storage executes copy processing of migrating, from the migration source volume to the migration destination volume, data in an assigned area of a virtual volume according to thin provisioning of the migration source volume based on the information contained in the first thin provisioning information in the first storage, and copying that data from the migration destination volume to a virtual volume according to thin provisioning of a copy destination volume in the second storage. The second storage associates the virtual volume of the copy destination volume with the migration destination volume in substitute for the original virtual volume.

    摘要: A multiple disk system comprises plural physical drives organized as plural groups of disks. Each group is accessed as a plurality of logical volumes. One of the logical drives is considered a primary volume and one or more other logical volumes are considered as secondary volumes, which together constitute a mirroring group. Data contained in a memory records such organization. The data is consulted to select a secondary volume when the disk group containing a primary volume fails.

    摘要: Long-term preservation of data (archive) has become more important. In order to reduce the maintenance cost for data, a first storage system consolidating a disk system and an MT library system has a disk interface with respect to a host computer and has a function of storing a logical volume in an MT. In addition, the first storage system has a function of managing information such as information indicating in which MT the logical volume is stored, and in which slot of a library the MT is stored. By using such functions, it is possible to integrally manage storage areas of the disk system and the MT library as logical volumes, thereby reducing the management cost.

    摘要: In general, a DRAM is used as a cache memory, and when attempting to expand the capacity of the cache memory to increase the hit ratio, the DRAM is required to be physically augmented, which is not a simple task. Consequently, a storage system uses a page, which conforms to a capacity virtualization function (for example, a page allocatable to a logical volume in accordance with Thin Provisioning), as a cache area. This makes it possible to dynamically increase and decrease the cache capacity.

    摘要: A first virtual storage and a second virtual storage share an external LU (Logical Unit) inside an external storage. The first virtual storage comprises a first LU, which comprises multiple first virtual areas and conforms to thin provisioning, and an external capacity pool, which is a storage area based on the external LU, and which is partitioned into multiple external pages, which are sub-storage areas. The second virtual storage comprises a second LU, which comprises multiple second virtual areas and conforms to thin provisioning. In a data migration from the first LU to the second LU, for a data migration from a first virtual area, to which an external page has been allocated, to a second virtual area, the first virtual storage notifies the second virtual storage of a migration-source address, which is an address of the first virtual area, and an external address, which is an address of the external page that has been allocated to this virtual area, and the second virtual storage stores a corresponding relationship between the notified migration-source address and external address.
