摘要： In a data processing system in which main and sub disk storage devices are under the control of individual each disk control devices, the write processing time is reduced by selectively sending data according to the command-chaining time between main and sub disk control devices. A section for judging cable length and function of the sub disk control device 36 estimates command-chaining time between a pair of main and sub disk storage devices. The channel command analyzing section 31 estimates the number of records to be transferred and the length of a record using a LOCATE RECORD command. The command judgment section for the sub disk control device 32 optimizes the command-chain to be issued to the sub disk control device using the above-mentioned information. Then, the section for issuing command to the sub disk control device 35 issues the optimized command chain. Thus, a shorter transmission time is realized by either sending individual records or an entire track of data.

摘要： In order to enable data migration between old and new subsystems to be performed under stopless operation, a plurality of first access paths and are prepared between a CPU and an old CU (old subsystem) having an old VOL and a plurality of third access paths and are set between the old CU and a new CU (new subsystem) having a new VOL. The connection is switched from the first access paths and of the old subsystem as a replacement source to the second access paths and of the new subsystem as a replacement destination on a plurality of occasions. When the CPU accesses the new subsystem via the second access paths and on the new subsystem side during the connection change, a path replacement controller relays the access to the old subsystem via the third access paths and and allows the access to be processed. Data migration from the old subsystem to the new subsystem is executed after all of the first access paths are switched to the second access paths.

摘要： With the purpose of achieving consistent non-synchronous copying of data from a plurality of primary side control units to a plurality of secondary side control units, all of the secondary side control units are connected via a loop, and each of the secondary side control units determines guarantee time by circulating a time added to the data received from the primary side control units via said loop communication route. A consistent data copying is guaranteed by circulating the determined guarantee time via the loop communication route.

摘要： Two data centers located in the vicinity are connected using a synchronous transfer copy function, and one of the data centers is coupled with a third data center disposed at a remote location by an asynchronous remote copying function. The order whereat a storage sub-system located in the vicinity has received data from a host is consistently guaranteed, and the third data center holds the data. Further, each storage sub-system includes a function whereby, during normal operation, data can be exchanged and the data update state can be obtained by the storage sub-systems located in the two data centers that do not directly engage in data transmission.

摘要： A storage apparatus system comprises first and second data storage systems. The first data storage systems can copy an image of data stored therein to the second data storage system without affecting access to storage in the first data storage system. In addition, failover processing is provided between the first and second data storage systems, wherein the second data storage system serves as the failover system.
