    摘要： Provided is a method, system, and an article of manufacture for maintaining data accessible by a host in two storage devices, wherein the data is comprised of a plurality of data sets. A determination is made of a percentage of uncopied data at the first storage device, wherein uncopied data comprises data sets to be copied from the first storage device to the second storage device. If the calculated percentage is greater than a threshold amount, a rate at which uncopied data sets are transferred from the first storage device to the second storage device is increased.

    摘要： A plurality of processing entities of a computer processing system employ messages for communicating with each other, and are updatable to newer versions at each of the processing entities by an initialization process. To maintain continuous availability, compatibility for the messages is established between the processing entities by maintaining, for message types, at each processing entity, identification values of the maximum and of the minimum versions of the message type supported at the entity. An initializing processing entity requests the maximum and minimum version identification values for the message types from other processing entities of the system. The initializing entity compares its maintained maximum and minimum version identification values to received maximum and minimum version identification values, and selects, as its current version, the maximum version whose identification value intersects with the maintained maximum and minimum version identification values and the maximum and the minimum version identification values of all the other processing entities.

    摘要： Disclosed is a system, method, and an article of manufacture for preferentially keeping an uncopied data set in one of two storage devices in a peer-to-peer environment when data needs to be removed from the storage devices. Each time a data set is modified or newly created, flags are used to denote whether the data set needs to be copied from one storage device to the other. The preferred embodiments modify the timestamp for each uncopied data set by adding a period of time, and thus give preference to the uncopied data set when the data from the storage device is removed based on the least recently used as denoted by timestamp of each data set. Once the data set is copied, the timestamp is set back to normal by subtracting the same period of time added on when the data set was flagged as needing to be copied.

    摘要： A portion of digital data records are stored on a direct access storage device (DASD) in emulation of sequential-access media when the parent digital data records are transferred to a sequential-access media. The efficiency of storage and access to the data portion is improved by random-access recall of the data in the data portion, and by constructing a data portion trailer containing various statistics about the records for referencing the digital data and advancing to target data. The volume data portion trailer is constructed as read forward and forward space block operations are performed. Data is preferably stored in logically assembled records. Interspersed with the records, there may be one or more marker codes, which function like tape marks among the various data records. The volume trailer may contain pointers to each record, a record count and marker codes for the data portion. Statistics contained in the data portion trailer enable substantially more efficient access of the data by a DASD.

    摘要： A data storage system provides a method and apparatus for preserving consistency between a database back-up and a set of storage volumes. The system includes a storage manager, or storage controller, interconnected to a plurality of storage volumes, a drive, and a database storage. The storage manager receives data files from an attached data processing unit. The storage manager directs the data files such that the files are written to a selected storage volume loaded into the drive. The storage manager maintains reference information and storage volume location information for each data file in the database storage. The storage manager detects a volume full condition when the storage media approaches a predetermined position prior to the physical end of the volume. The storage manager generates a back-up copy of the current database, transfers the database back-up to the drive, and directs the drive to write the database back-up onto the selected storage volume. Thus, each selected storage volume contains a database back-up which remains consistent with the data files currently stored on the selected storage volume and previously stored on previously selected storage volumes.

    摘要： A data storage system stores logical data object(s), each identified by a logical identifier. A control is configured to assign a unique WORM (Write Once Read Many) identifier to the logical data object, and stores the unique WORM identifier as associated with the logical identifier, in a database maintained by the control so as to be persistent. Data storage is configured to write the logical data object with a header with the unique WORM identifier. The control, in order to allow the logical data object to be accessed externally to the control, requires matching the unique WORM identifier in the header of a logical data object to the unique WORM identifier of the persistent database for the logical object. The unique WORM identifier is formed of a checksum hash value related to nonce fields comprising at least the logical identifier of the logical data object, an incrementing token, and a time stamp.

    摘要翻译： 数据存储系统存储逻辑数据对象，每个逻辑数据对象由逻辑标识符标识。 控制被配置为向逻辑数据对象分配唯一的WORM（一次读取多个）标识符，并且将与逻辑标识符相关联的唯一WORM标识符存储在由控制器维护的数据库中以便被持久化。 数据存储被配置为使用具有唯一WORM标识符的报头来写入逻辑数据对象。 为了允许将逻辑数据对象从控制外部访问，控制需要将逻辑数据对象的头部中的唯一WORM标识符与逻辑对象的持久性数据库的唯一WORM标识匹配。 独特的WORM标识符由与至少包括逻辑数据对象的逻辑标识符，递增令牌和时间戳的至少包括的nonce字段相关的校验和散列值形成。

    摘要： Link information for a plurality of links to at least one target node indicates for each link a send throughput for sending data, a receive throughput for received data, a slate of the link indicating whether the link is online, offline or degraded. The send throughput of the links having the online state is processed to select one of the links to the receiving node m response to determining that more than one of the links has the online state. The data of the send operation is sent using the selected link to the receiving node. The receive throughput is processed to select one of the links having the online state to the sending node in response to determining that more than one of the links has the online state. The data of the receive operation is received using the selected link to the sending node.
