摘要： A storage apparatus includes a drive unit in which a logical unit is formed, and a controller unit for accessing the logical unit by controlling the drive unit according to an access request sent from a host apparatus. The storage apparatus issues a logical unit takeover request to the other storage apparatuses, allocates a logical unit of another storage apparatus that will accept the transfer of the logical volume to its own logical unit according to a takeover approval sent from other storage apparatuses in response to the takeover request, and thereafter migrates data of the own logical unit to a logical unit of another storage apparatus. Subsequently, the path is switched so that the access request from the host apparatus is given to one of the other storage apparatuses.

摘要： Proposed is a storage controller and its control method for speeding up the processing time in response to a command in a simple manner while reducing the load of a controller that received a command targeting a non-associated logical volume. This storage controller includes a plurality of controllers for controlling the input and output of data to and from a corresponding logical unit based on a command retained in a local memory, and the local memory stores association information representing the correspondence of the logical units and the controllers and address information of the local memory in each of the controllers of a self-system and another-system. Upon receiving a command sent from a host computer, the controller determines whether the target logical unit is associated with the controller of a self-system or another-system based on the association information, and, when the logical unit is associated with the other-system controller, the controller transfers and stores the command to and in the corresponding other-system controller based on the address information.

摘要： During iSCSI communication, according to the contents of commands issued by a host computer, the command response time is increased due to the influence of the TCP Delayed ACK. Thus, a command issued by the host computer is analyzed, the number of TCP/IP packets required for transmitting the data requested by this command is calculated, and a precedence packet is transmitted, so that no influence is experienced due to the Delayed ACK.

摘要： A storage control apparatus stores a device attribute that indicates whether a physical storage device that is made to be a basis of a pool of a creation target is an encryption device (a physical storage device that is provided with an encryption function) or an unencryption device (a physical storage device that is not provided with an encryption function) as a pool attribute for the pool. In the case in which a pool attribute that has been stored for a pool with which a virtual volume that is a virtual logical volume of a creation target is associated indicates both of an encryption and an unencryption, the storage control apparatus associates the virtual volume of a creation target with a physical storage device that conforms to an attribute that has been specified as a volume attribute of the virtual volume of a creation target among an encryption device and an unencryption device that are a basis of a pool of the associated destination. The storage control apparatus stores a volume attribute of the virtual volume of a creation target.
