摘要： A data processing system includes at least a first storage system, a second storage system and a third storage system. The third storage system maintains a replication of data stored in the first storage system. When updating data in the first storage system, the first storage system updates the replication of data stored in the third storage system and creates a journal. The journal is formed from a copy of data used for update and update information such as a write command for update, etc. The second storage system also maintains a replication of data stored in the first storage system. The second storage system obtains the journal, and updates data stored therein corresponding to data stored in the first storage system in the order of data update performed in the first storage system. When updating data stored in the third storage system corresponding to data stored in the first storage system, the third storage system creates a journal using data update numbers created in the first storage system. When the first storage system fails, the second storage system obtains the journal from the third storage system, and updates data stored therein corresponding to data stored in the first storage system in the order of data update performed in the first storage system.

摘要： A data processing system has a plurality of storage systems. In this system, data replication is performed at high speed and efficiency while maintaining data integrity. In addition, when failure has occurred in a configuration element, the time necessary to resume the data replication is reduced. In accordance with an instruction from first host computer, updating of replication-target data and creation of a journal are performed in a storage system A; and updating of replication data and creation of a journal are performed in a storage system B. A storage system C retrieves a journal from the storage system B in asynchronization with the updating, and performs updating of replication data. When failure has occurred in the storage system B, a journal-retrieving end is altered to the storage system, and the replication data is updated in accordance with the retrieved journal.

摘要： In a configuration in which it is necessary to transfer data from a first storage system to a third storage system through a storage system between the storage systems, there is a problem that it is inevitable to give an excess logical volume to a second storage system between the storage systems. A remote copy system includes first storage system that sends and receives data to and from an information processing apparatus, a second storage system, and a third storage system. The second storage system virtually has a second storage area in which the data should be written and has a third storage area in which the data written in the second storage area and update information concerning the data are written. Data sent from the first storage system is not written in the second storage area but is written in the third storage area as data and update information. The data and the update information written in the third storage area are read out from the third storage system.

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 allocating an area of a cache memory to each storage unit, proper allocation of the cache memory is made to each storage unit. If the amount of write-after data becomes equal to or more than a threshold value, an allocation limit is set to each disk unit. If CPU issues a data write request requiring the amount of data equal to or more than the allocation limit, the data write request is held in a wait state until the amount of write-after data becomes less than the allocation limit. Therefore, the allocation amount to the disk unit becomes neither too large nor too small. In this manner, proper allocation of the cache memory to each disk unit can be realized.
摘要翻译：在向每个存储单元分配高速缓冲存储器的区域时，对每个存储单元进行高速缓冲存储器的适当分配。如果写入数据量等于或大于阈值，则对每个盘单元设置分配限制。如果CPU发出数据写请求，要求数据量等于或大于分配限制，则数据写入请求将保持在等待状态，直到写入数据量小于分配限制为止。因此，对于盘单元的分配量既不太大也不太小。以这种方式，可以实现对每个盘单元的高速缓冲存储器的适当分配。

摘要： A disk cache control unit disposed between an upper-rank processor and a disk unit, comprising a cache memory for holding a copy of data stored in the disk unit, at least one first interface controller which checks, in response to an input/output command requesting data to be read from the upper-rank processor, whether or not the data requested by the command is stored in the cache memory, and requests a head positioning of the disk unit when the data is not stored in the cache memory, and a second interface controller which indicates head positioning to the disk unit in response to a head positioning request, notifies the completion of the head positioning to the first interface controller in response to a notice of the completion of the head positioning, and which reads data from the disk unit and stores the data in the cache memory when a data transfer request did not come in a specified time period set to read data from the disk unit without a rotational delay after a notice of the head positioning head been given to the first interface controller and the subsequent transfer of data from the second interface controller had been completed, and which gives a notice of storage of the data in the cache memory through memory means to the first interface controller, and in response to this storage notice, the first interface controller reads the data from the cache memory and transfers the data to the upper-rank processor.
