摘要： By incorporating a referral mechanism, a failover method and system for remotely mirrored clustered file servers enables a client computer to transparently access a remotely mirrored file system during a failover of a first NAS (network attached storage) storing the file system. The first NAS is clustered with a second NAS that takes over the IP address of the first NAS on failover. A mirroring relationship is established between the first NAS and a third NAS whereby a copy of the file system is replicated to the third NAS. A referral is created on the second NAS, such that an access attempt from the client computer for accessing the first file system that is directed to the second NAS following IP address takeover from the first NAS after failover is referred to the third NAS by the referral to enable the client computer to access the copy of the file system.

摘要： A system and method for managing transactions of application programs at a storage system enables data protection on a per-transaction basis. The storage system receives an instruction indicating a beginning of a transaction, and determines at least one primary volume for receiving data for the transaction. The storage system also provides a log volume for initially storing write data designated for the primary volume associated with the transaction. When the transaction is successfully completed the data stored in the log volume for the transaction is applied to the primary volume.

摘要： A storage system conducting remote copy functions such that, when data is updated at a local site, contents of the update can be referred to in real time by storage at a remote site. A disk-control unit at a remote site receives file data written in accordance with an update of a file in a storage system at a local site and a history of the file-management information from the storage system at the local site and stores the data and the history. A file-system processing unit refers to the history and updates the file-management information in a file-system cache in accordance with the update of the file in the storage system at the local site. When a client issues a read request, the file-system processing unit refers to the file-management information updated in the file-system cache and transfers the contents of the update of the file to the client.

摘要： A system for performing efficient backup in an environment where a plurality of file servers exist, making the plurality of file servers externally look like a single apparatus. The present invention provides a computer system comprising hosts, first and second file servers connected to the hosts, and a storage system connected to the first and second file servers. The second file server determines that a file as a backup object is managed by the first file server, and notifies the first file server of an instruction of backup. In response to this instruction, the first server sends the second file server an identifier of a storage device that stores duplicate data of the file in question. Based on the received identifier, the second file server sets a path to that storage device, and obtains the backup data from that storage device.

摘要： Copy-on-write snapshot processing is performed on a storage system in order to produce snapshots of one or more logical volumes in the storage system. The write I/O operations made to the storage system are observed for a certain period of time. Based on the observations an estimate of the size of the storage space required to preserve the snapshot data can be computed. The information can be used to provide sufficient storage space for the snapshot process.

摘要： The system is disclosed in which a storage system having data, and meta-data which describes attributes of the data including its address, can copy the data to a secondary system in a more efficient manner. The storage system identifies the blocks which contain the data described in the meta-data, then reads those blocks in the order of their addresses and copies them to the desired target. The method reduces disk access time and thereby speeds copy operations.

摘要： A system for managing clock adjustment in a storage system is provided. The system includes a clock configured to provide a current time, wherein the current time is used to enforce a content retention period, a memory configured to store clock management information, wherein the clock management information includes a last adjustment time and a number of maximum adjustable time ranges, wherein the last adjustment time represents the time which the clock was last adjusted, and a storage access program. The storage access program is configured to receive a proposed new time for the clock, determine whether the proposed new time is reasonable using the current time, the last adjustment time and a specific range selected from the maximum adjustable time ranges, and adjust the current time of the clock to the proposed new time if it is determined that the proposed new time is reasonable. The storage access program is further configured to prevent adjustment of the clock to the proposed new time if it is determined that the proposed new time is unreasonable.
