摘要： A clustering storage system, which enables to operate a plurality of storage system units as a single storage system, presents connection information between clustering storage systems to a user and receives data to be backed up and an instruction about a path between the clustering storage systems from the user. The clustering storage system uses load information or a transfer speed of a data connection line between the storage system units to determine a path between the clustering storage systems used for backup and a storage system unit for holding a backup copy so that the data transfer between the storage system units becomes minimum. Besides, the clustering storage system mainly uses the determined path for backing up the data.

摘要： A remote copy system includes a plurality of first storage systems and a plurality of second storage systems. Each first storage system assigns a sequential number to write data received from the host and sends the write data with the sequential number to the second storage system. One of the first storage systems defers the processing of the write request received from the host and instructs each of the first storage systems to create a marker, whereupon each of the first storage systems defers the processing of the write request, creates a marker including a sequential number and having a marker number, and sends the marker to the second storage system. Each of the second storage systems, when receiving a marker from the first storage system, stores the marker number included in the marker. One of the second storage systems reads the marker number stored by each of the second storage systems and reports to each of the second storage systems the marker number of smallest value of the marker numbers which were thus read. Each of the second storage systems writes to a logical volume in sequential number order write data, of the write data received from the first storage system, that includes a sequential number of a value smaller than the sequential number of the marker including the marker number reported from one of the second storage systems.

摘要： In a system in which data employed by a computer is stored in a storage system, the storage system transfers this data to another storage system and a copy of the data is maintained in the other storage system. The consistency of the copy is maintained even when data is written, to the storage system by a computer, without having a write time applied. A source storage system, when a write time is applied to a write request, records the write time and applies this write time to the received write data and, when no write time is applied, applies the recorded write time to the received write data and transfers the write data with this write time applied thereto, to a target storage system. The target storage system stores the write data in a logical volume in the target storage system in accordance with the write time.

摘要： A storage control apparatus and a storage control method are provided wherein in a system having a plurality of disk systems and secondary disk systems at remote sites, the data transfer amount between a central processing unit and a disk system can be reduced when duplicate disk write is performed, the performance can be prevented from being degraded even if the distance between control units is elongated, and the intermediate results of a transaction are not left. A standard time is determined and a program is provided which instructs a secondary central processing unit to reflect only update information having a write time older than the standard time, upon a logical disk in the secondary disk system.

摘要： Even when a host does not give a write time to write data, consistency can be kept among data stored in secondary storage systems. The present system has plural primary storage systems each having a source volume and plural secondary storage systems each having a target volume. Once data is received from a host, each of the plural storage systems creates write-data management information having sequential numbers and reference information and sends, to one of the primary storage systems, the data, sequential number and reference information. Each of the secondary storage systems records reference information corresponding to the largest sequential number among serial sequential numbers and stores, in a target volume in an order of sequential numbers, data corresponding to reference information having a value smaller than the reference information based on the smallest value reference information among reference information recorded in each of the plural secondary storage systems.
