摘要： A host and a storage system each keep a shared identifier indicating a state of a system. The storage system acquires, at update of data, a data pair including data for a change through processing of the host and data before the update. The storage system relates the data pair to a shared identifier. When the host indicates an identifier, the storage system restores data using the data pair.

摘要： In a storage system comprising multiple storage devices with different interfaces, the characteristics, including the type of interface, of the storage devices on which the source volume is constructed are checked, a volume having the characteristics that match them is selected as the destination volume, and the contents of the source volume are automatically replicated into the destination volume. Candidates for replication (destination) volumes are automatically selected and presented to the user or the administrator, and replication volumes are automatically allocated, without requiring the user or the system administrator to be concerned with the characteristics of the storage devices.

摘要： In a storage subsystem, performance tuning is performed with respect to all of the logical devices including external storage subsystems that are not directly connected to host computers. The physical storage units presented by the external storage subsystems are defined as logical devices of the storage subsystem, and I/O processing requests from the host computers are relayed to the logical devices. At the time of relaying, I/O processing conditions are monitored. When the load of an external storage subsystem is high, then operating conditions of ports and processors are examined. When the load can be reduced by changing the configuration of those ports and processors, the configuration is changed to reduce the load. When the load can not be reduced, data is migrated from a logical device having a high load to a logical device having a sufficient performance.

摘要： The data up to a point of time whereat failure has occurred will be restored at high speed at a remote site without imposing any burden on a host. The first storage system on the master side processes an I/O request from the host, and as a result of I/O processing to the second storage system on the remote side, transmits the update data. The second storage system retains data received from the first storage system as update log data. The host transmits a command for settling a state of an application to the first storage system as data, and the first storage system transmits the data to the second storage system. The host and the second storage system both retain an identifier corresponding to the command, and relate the identifier to the log data. Thereby, the host designates the identifier at any given time, whereby the second storage system restores the data at any given time.
摘要翻译：直到发生故障的时间点的数据将在远程站点高速恢复，而不会对主机造成任何负担。主机侧的第一存储系统处理来自主机的I / O请求，并且作为对远程侧的第二存储系统的I / O处理的结果，发送更新数据。第二存储系统将从第一存储系统接收的数据保留为更新日志数据。主机向第一存储系统发送用于确定应用状态的命令作为数据，并且第一存储系统将数据发送到第二存储系统。主机和第二存储系统都保留与该命令对应的标识符，并将该标识符与日志数据相关联。因此，主机在任何给定的时间指定标识符，由此第二存储系统在任何给定的时间恢复数据。

摘要： The present invention transfers replication logical volumes between and among storage control units in a storage system comprising a plurality of storage control units. To transfer replication logical volumes from a storage control unit to a storage control unit, a virtualization device sets a path to the storage control unit. The storage control unit then prepares a differential bitmap in order to receive access requests. When the preparation is completed, the virtualization device makes access requests to the storage control unit. The storage control unit then hands over the access requests to the storage control unit. Subsequently, the storage control unit performs a process so that the access requests are reflected in a disk device and performs an emergency destage of storing data in a cache memory into disk device. When the emergency destage is ended, the storage control unit connects to an external storage control unit and hands over access requests to the external storage control unit.

摘要： The storage system includes a storage subsystem including a plurality of storage units and a storage control device coupled to a computer and the storage subsystem, the storage control device providing the host computer with a logical unit assigned to a storage unit of the storage subsystem. The storage control device receives a first access request from the computer to the logical unit and sends a second access request to the storage unit of the storage subsystem according to a relation between the storage unit of the storage subsystem and the logical unit assigned to the storage unit. Performance information relating to the second access request by the storage control device is obtained so that the storage control device determines performance relating to the logical unit assigned to the storage unit of the storage subsystem.
