摘要： Various embodiments for replicating deduplicated data using a processor device are provided. A block of the deduplicated data, created in a source repository, is assigned a global block identification (id) unique in a grid set inclusive of the source repository. The global block id is generated using at least one unique identification value of the block, a containing grid of the grid set, and the source repository. The global block id is transmitted from the source repository to a target repository. If the target repository determines the global block id is associated with an existing block of the deduplicated data located within the target repository, the block is not received by the target repository during a subsequent replication process.
摘要翻译：提供了使用处理器设备复制重复数据删除的数据的各种实施例。在源存储库中创建的重复数据删除数据块被分配在包含源存储库的网格集中唯一的全局块标识（id）。使用块的至少一个唯一标识值，包含网格集合的网格和源存储库来生成全局块ID。全局块id从源存储库传输到目标存储库。如果目标存储库确定全局块id与位于目标存储库内的已重复数据消除的数据的现有块相关联，则在后续复制过程中该目标存储库不会接收该块。

摘要： Communication is arrested between a source data entity and a replicated data entity at a location declared in a DR mode. The DR mode is negotiated to a central replication management component as a DR mode entry event. The DR mode entry event is distributed, by the central replication management component, to each member in a shared group. The DR mode is enforced using at least one replication policy.
摘要翻译：通信在源数据实体和在DR模式下声明的位置的复制数据实体之间被阻止。将DR模式协商为中央复制管理组件作为DR模式入口事件。 DR模式条目事件由中央复制管理组件分发给共享组中的每个成员。使用至少一个复制策略强制实施DR模式。

摘要： Visibility of a data storage entity on a first storage system is switched to a replicated data storage entity on a second storage system. Data from the data storage entity is replicated from the first storage system to the second storage system using a common serial number. The data storage entity is hidden from the first storage system by concealing the common serial number. An ejection of the data storage entity from the first storage system is automated, and the replicated data storage entity is introduced to the second storage system.
摘要翻译：第一存储系统上的数据存储实体的可见性被切换到第二存储系统上的复制数据存储实体。来自数据存储实体的数据使用公共序列号从第一存储系统复制到第二存储系统。通过隐藏公共序列号，数据存储实体从第一存储系统隐藏。从第一存储系统弹出数据存储实体是自动的，并且将复制的数据存储实体引入第二存储系统。

摘要： Pursuant to execution of a predetermined failback policy, if a storage device is not preexistent in a source storage system operable in the computing environment, and an owner of the storage device is one of a DR storage system and a storage system having previously withdrawn from a replication grid, and the DR storage system has authorization to transfer ownership of the storage device by a replacement operation, an instance of the storage device is replicated to the source storage system to generate a replicated instance of the storage device on the source storage system, and ownership of the storage device is designated as the source storage system for each of the instance and the replicated instance of the storage device.

摘要： Various embodiments for disaster recovery (DR) production takeover in a computing environment by a processor device are provided. If, for a designated storage system operable in the computing environment, a takeover operation may be executed, and a DR storage system has validly replaced the designated storage system using a replacement process, a withdrawal of a DR mode of operation is performed, and ownership of at least one storage device operable in the computing environment is transferred to the DR storage system. The replacement process authorizes the DR storage system to transfer the ownership while withdrawn from the DR mode of operation.

摘要： A plurality of workers is configured for parallel processing of deduplicated data entities in a plurality of chunks. The deduplicated data processing rate is regulated using a rate control mechanism. The rate control mechanism incorporates a debt/credit algorithm specifying which of the plurality of workers processing the deduplicated data entities must wait for each of a plurality of calculated required sleep times. The rate control mechanism is adapted to limit a data flow rate based on a penalty acquired during a last processing of one of the plurality of chunks in a retroactive manner, and further adapted to operate on at least one vector representation of at least one limit specification to accommodate a variety of available dimensions corresponding to the at least one limit specification.
摘要翻译：多个工作者被配置用于并行处理多个块中的重复数据删除的数据实体。使用速率控制机制来调节重复数据删除的数据处理速率。速率控制机制包括债务/信用算法，其指定处理重复数据删除的数据实体的多个工作者中的哪一个必须等待多个计算的所需睡眠时间中的每一个。速率控制机制适于基于在追溯方式的多个块中的一个块的最后一个处理期间获取的惩罚来限制数据流速，并且还适于对至少一个限制规范的至少一个向量表示进行操作以适应与至少一个限制规格对应的各种可用尺寸。
