摘要： A storage control system judges whether the data pattern of data exchanged with a higher-level device (hereafter “data”) conforms to one or a plurality of write-excluded data patterns comprised in write-excluded data pattern information prepared in advance. If a negative judgment result is obtained, the storage control subsystem stores the data in a logical device formed on a disk storage device. If, on the other hand, a positive judgment result is obtained, the storage control subsystem erases the data without storing in a logical device.
摘要翻译：存储控制系统判断与上级装置（以下称为“数据”）交换的数据的数据模式是否符合预先准备的写入排除数据模式信息中包含的一个或多个写入排除数据模式。如果获得否定判断结果，则存储控制子系统将数据存储在形成于盘存储装置上的逻辑装置中。另一方面，如果获得肯定判断结果，则存储控制子系统在不存储在逻辑设备中的情况下擦除数据。

摘要： A method and apparatus which provide solutions for avoiding journal overflow in after and before journal methods of a backup and recovery system used with a storage system. The after journal method solutions, which are conducted when the amount of free space reaches a threshold, include periodically taking a new snapshot and deleting the oldest journal, periodically taking a new logical snapshot and deleting the oldest journal, stopping the taking journal entries when the journal volume is full, and stopping the taking journal entries when the journal volume is full and then switching to bitmap management. The before journal method solution, which is conducted when the amount of free space reaches a threshold, includes applying wrap-around overwriting to overwrite the oldest journal entry by the newest journal entry.

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： The present invention provides techniques for managing storage based replication. Specific embodiments provide techniques for performing system backup and restoring. In specific embodiments, benefits such as keeping a remote mirror between a primary volume and a secondary volume in operation can be provided. Since the remote mirror is usually used for disaster recovery purposes, where the mirrors must be always in-sync state, being able to take a backup without breaking the remote mirror can help provide a constant duplicate copy of production information in case of emergency, for example. Further, in some embodiments, a user can take backups of more than one generation by setting up two or more secondary volumes (SVOLs) for one primary volume (PVOL).

摘要： Provided is a storage control system in which a number of storage controllers are connected, and restored data is forwarded from one storage controller to the other storage controller. With this storage control system, even when the host system accesses the logical volume of the forwarding destination of the restored data, the host system will be able to reliably access the restored data. This storage control system is configured by a first storage controller and a second storage controller being connected in a mutually communicable manner, and which performs data processing according to a request from a host system, the first storage controller having a virtual volume associated with a logical volume of the second storage controller; a cache memory associated with the virtual volume; and a control unit for controlling the data processing between the cache memory and the virtual volume; wherein the control unit purges the storage area of the cache memory corresponding to the virtual volume accessed by the host system upon storing the restored data of the logical volume in the cache memory.

摘要： In a computer system having a computer, a storage system having storage units being coupled to the computer and for storing user data used by the computer, and a backup device being coupled to the computer and the storage system, a backup method is presented for obtaining a backup of the data stored in the storage unit to the backup device. The storage system holds the user data dually in a first and a second storage units. In backing up the user data, a split instruction for releasing the duplex state of the first and the second storage units is sent from the computer to the storage unit. In response to the split instruction, the storage system interrupts the reflection of the update of the user data to the first storage unit onto the second storage unit. Then, a copy instruction for copying the user data held in the second storage unit to the backup device is sent from the computer to the storage system. The storage system operates to transfer the user data inside of the second storage unit to the backup device in response to the copy instruction.

摘要： A storage network device responds in a positive or negative manner to a connection request from another storage network device, based on vendor or manufacturer-related information. In this way, subsequent communication can be prevented. This is advantageous for limiting access to a device by devices which are properly certified, or otherwise sufficiently tested, thus improving reliability and performance.
