摘要： A file to be written can be partitioned into one or more partitions. Each such input partition is identified with a hash code and a group ID. Replica(s) of an input partition can be created to ensure a certain number of identical partitions. When a file is accessed, each partition that is read out can be checked for corruption. Corrupted readout partitions are then replaced with a validated replacement partition, whether the replacement partition is from a replica or from another file.

摘要： A hierarchical storage data management system includes application servers, a metadata server interconnected with the application servers through a local area network, storage devices interconnected through data flow paths, and a storage network connecting the storage devices to the application servers and to the metadata server. The metadata server including a metadata management element, a data value management unit, and a hierarchical storage management element calculates a data value for each of stores data objects in the system, assigns a storage cost value for each of storage areas in the system, normalizes calculated data values and assigned storage costs to an identical value range, compares normalized data values with normalized storage costs thereby determining whether to relocate the data objects to different storage areas, and relocates data objects to storage areas with storage cost values identical with data values of the data objects.

摘要： A method for operating a storage system configured to provide a Write Once and Read Many (WORM) function includes receiving a first command at a storage subsystem from a host. At least a portion of the first command is stored on a WORM storage device coupled to the storage subsystem. A second command is received at the storage subsystem. The second command is examined using a command filter, the filter being provided with a predetermined rule for filtering selected types of commands. At least a portion of the second command is stored if the second command satisfies the predetermined rule. The WORM storage device is used to verify the WORM function of the storage system.

摘要： A secure data mirroring capability in a storage system includes encrypting data blocks in a primary volume in preparation for a data mirroring operation. The encrypted data blocks are mirrored to a secure secondary volume. Host systems provide keys from which encryption keys are produced for encrypting the data blocks. Access to data on the secure secondary volume requires decryption using the key that was used to produce the encrypted data blocks.

摘要： Data at a primary storage system is encrypted and remote copied to a secondary storage system. A Remote Copy Configuration Information (RCCI) is created that identifies the encryption mechanism, keys, data source volume, and target volume for the remote copy. The RCCI is backed up on a trusted computer system. In one embodiment, the secondary storage system is an off-site data storage system managed by a third party. Upon detection of a failure in the primary storage system, the encrypted data and RCCI are transferred to a tertiary server, which is optionally created upon detection of the failure, and operations of the failed primary server are resumed by the tertiary server. In one embodiment, the failure is detected by loss of a heart beat signal transmitted from the primary storage system to a management server that initiates the transfers to the tertiary server.

摘要： The present invention provides techniques for answering a user's query to a database system. An embodiment provides a database querying method in which a first data item is obtained from a Data Base Management System (DBMS) database table in response to a query request. A second data item is obtained by referencing a DBMS updated log file, having log data associated with the first data item, for example a timestamp. The first and second data items are then integrated and returned as an integration result to the query request. In one embodiment the first and second data items are integrated in a virtual table in accordance with a predetermined business rule.
摘要翻译：本发明提供了用于将用户的查询应答到数据库系统的技术。实施例提供一种数据库查询方法，其中响应于查询请求从数据库管理系统（DBMS）数据库表获得第一数据项。通过引用具有与第一数据项相关联的日志数据（例如时间戳）的DBMS更新的日志文件来获得第二数据项。然后将第一和第二数据项集成并作为集成结果返回给查询请求。在一个实施例中，根据预定的业务规则将第一和第二数据项集成在虚拟表中。
