摘要： A continuous update method includes reading out data from a first data store via a data switch to satisfy client requests for data. A second data store is updated via the data switch to contain new updated information. When it is desired to satisfy client requests with the new data, the second data store is copied to a third data store and subsequent client requests are satisfied from the third data store. Further updates are made to the second data store. The process is repeated, but the roles of the third and first data stores are reversed. In another embodiment of the invention, subsequent client requests are satisfied from the second data store and further updates are made to the first data store.
摘要翻译：连续更新方法包括经由数据交换机从第一数据存储器读出数据以满足客户端对数据的请求。通过数据交换机更新第二个数据存储，以包含新的更新信息。当希望满足具有新数据的客户端请求时，第二数据存储被复制到第三数据存储器，并且从第三数据存储器满足随后的客户端请求。进一步更新到第二个数据存储。重复该过程，但是第三和第一数据存储的作用被颠倒。在本发明的另一个实施例中，从第二数据存储器满足随后的客户端请求，并对第一数据存储进行进一步的更新。

摘要： A multiple disk system comprises plural physical drives organized as plural groups of disks. Each group is accessed as a plurality of logical volumes. One of the logical drives is considered a primary volume and one or more other logical volumes are considered as secondary volumes, which together constitute a mirroring group. Data contained in a memory records such organization. The data is consulted to select a secondary volume when the disk group containing a primary volume fails.

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 system is provided which preserves data integrity, even when communications line, or similar, errors arise between the local disk system and the remote disk system. When there is no communication line error between the local disk system and the remote disk system, the local disk system sends a time stamp or the write order information with the write data to the remote disk system. This enables the remote disk system to make a copy with data integrity on the disk unit in the remote disk system itself. If there is a communication line error, the remote disk system allocates an empty disk unit and makes a copy with data integrity on the allocated disk unit after the communication line error between the local disk system and the remote disk system is detected.
摘要翻译：即使在本地磁盘系统和远程磁盘系统之间出现通信线路或类似的错误，也提供了保存数据完整性的存储系统。当本地磁盘系统与远程磁盘系统之间没有通信线路错误时，本地磁盘系统将写入数据的时间戳或写入顺序信息发送到远程磁盘系统。这使远程磁盘系统能够在远程磁盘系统本身的磁盘单元上复制数据。如果存在通信线路错误，则在检测到本地磁盘系统和远程磁盘系统之间的通信线路错误之后，远程磁盘系统将分配空的磁盘单元，并在分配的磁盘单元上复制数据。

摘要： In a storage system, a logical volume is divided into a plurality of small areas called logical storage devices and only such an area designated by a user is made an object of remote copying or migratory copying. Also, there is provided a unit for forming a logical volume from any logical storage device of any RAID group. Thereby, the reduction of the deterioration in performance at the time of remote copying, the reduction of a storage area to be assigned to a secondary site as a copy destination, the shortening of a time required for migratory copying and the assignment of any area of a logical volume on any RAID group are enabled.

摘要： A data sharing method for use in a computer system provided with a first computer, a second computer and a data storage subsystem for connection with the first and second computers is disclosed. The data storage subsystem has a plurality of memory units and a control unit for controlling the plurality of memory units. The control unit forms a paired state of a first memory unit storing data for use by the first computer and a second memory unit, the paired state being so controlled as to match the contents of the first memory unit and those of the second memory unit. When data used by the first computer are to be used by the second computer, the control unit releases the paired state between the first memory unit and the second memory unit to stop updating of the first memory unit to be reflected in the second memory unit. After that, the control unit re-maps a third memory unit used by the second computer and the second memory unit with each other, and so performs control that the access by the second computer to the third memory unit be made to the second memory unit.
