摘要： To enhance capacity expansion property of a storage system for providing a thin provisioning volume, this invention provides a computer system including: a first storage system; and a second storage system for providing a second volume to the first storage system. The first storage system is configured to: define at least one first volumes; define a first storage pool including the defined first volume and the provided second volume; provide to the host computer a first thin provisioning volume that is recognized as a volume having a capacity equal to or larger than that of storage areas assigned from the first storage pool. The first thin provisioning volume is thus assigned with both storage areas of the first volume and storage areas of the second volume, which are included in the first storage pool.

摘要： A storage system is connected to a computer, and a name server exercising control over the interrelation between initiators and targets, and includes a first storage node and a second storage node. The first storage node has a first logical unit to which a first target is set, and the second storage node has a second logical unit. For data migration from the first logical unit to the second logical unit, the first storage node forwards data stored in the first logical unit to the second storage node, and the second storage node stores the data into the second logical unit. The first storage node also forwards information about the first target to the second storage node, and the second storage node sets a target to the second logical unit using the received information about the first target.

摘要： A storage device managing one or more logical volumes is connected with a name management device through an IP-SAN 6 composed of a switch. The storage device stores a topology table saving connecting relation among physical ports of host, physical ports of the storage device and physical ports of the switch, reads an identifier of the host and an identifier of the logical volume, selects a unused first physical port of the switch by referring to the topology table, selects a second physical port of the switch connected with the storage device, registers a group composed of the host and the logical volume with the name management device, and executes a configuration of allowing packets to be transferred between the first and the second physical ports with respect to the switch.

摘要： A pool is formed based on a plurality of storage devices. This pool is constituted by a plurality of real pages. Real pages of different lengths are included in this plurality of real pages. Among a plurality of virtual pages which make up a virtual volume, a controller compresses a write data element for a write destination virtual page, selects a real page of a real page length based on the data length of a data unit including the compressed write data element, and allocates the selected real page to the write destination virtual page.

摘要： A storage system is provided which is capable of realizing a remote copy function for speeding up lines virtually by satisfying such demand to distribute copy data into a plurality of lines. In a storage system for connecting a local storage device and a remote storage device via a plurality of lines, the local storage device includes a remote copy program for distributing data of a plurality of logical volumes accessed from a host computer into a plurality of paths on the basis of status of the plurality of paths interposing the plurality of lines, to perform a remote copy from the local storage device to the remote storage device. Accordingly, the local storage device distributes data of the logical volumes into the plurality of lines to copy the data to the remote storage device, resulting in speeding up the lines virtually.

摘要： The storage system of the present invention is able to update a secret while maintaining a session between a host and storage. The administrator configures a new secret for the host and the storage. The session manager issues a request to the storage to open a session that uses the new secret. The session manager opens a session that uses the new secret following authentication. A response to an old command issued prior to the secret update is transmitted from the storage to the host via a session that uses an old secret. A new command following the secret update is transmitted from the host to the storage via the session that uses the new secret. When all the old command processing is complete, the old secret using session is closed.
