摘要： A data storage system writes data supplied from a host to data storage in accordance with write I/O of an owning application. A workload manager directs the processing of the supplied data in accordance with the write I/O of the owning application, provides service workload identification describing the write I/O, a storage subsystem control adds the service workload identification to record set information for the data, and a journal management system stores the record set information in a journal. The journaled information, for example, may be employed for performing forensic analysis of data corruption events or to perform security audits, etc.

摘要： Techniques are provided for resolving a collision between two copy services. A policy associated with a new copy service request is retrieved. Characteristics of an existing copy service request are determined. The effects of the new copy service request are determined. A resolution for the collision is identified based on the policy, the determined characteristics, and the determined effects.

摘要： Disclosed is a method, system, program, and data structures for maintaining electronic data at a point-in-time. A first data structure indicates point-in-time data at one of a first storage location and a corresponding second storage location. A second data structure indicates point-in-time data at one of a first storage location and corresponding second storage location. A first relationship data structure indicates a relationship between the first storage location and corresponding second storage location and a second relationship data structure indicates a relationship between the first storage location and second storage location. A request to process the first storage location is processed by processing the first relationship data structure to determine the corresponding second storage location for the first storage location and processing the first data structure to determine whether data at the first storage location was transferred to the second storage location. A request to process the second storage location is processed by processing the second relationship data structure to determine the corresponding first storage location for the second storage location and processing the second data structure to determine whether the point-in-time data at the first storage location was transferred to the second storage location.

摘要： Disclosed is a method, system, program, and memory for erasing data. A request to erase data at least one storage location is received. In response, a data structure is generated indicating that each storage location subject to the erase request is in an erased state. Upon processing a request to access a storage location, a determination is made as to whether the requested storage location is indicated in the data structure. The data structure is processed to determine whether the requested storage location is in the erased state after determining that the requested storage location is indicated in the data structure. Access to the data at the requested storage location is denied after determining that the requested storage location is in the erased state.

摘要： Source data is more efficiently copied to log structured target storage by pre-configuring the target storage. The invention may be practiced in a system including a host, a storage controller, and the target storage. The host maintains a directory identifying logical units of stored data, and the storage controller maintains records classifying storage space as uncollected free space, collected free space, or space-in-use. First, the host receives input including source data and specification of a logical unit for the source data. In response, the host directs the storage controller to classify any storage space of the log target storage containing data of the specified logical unit as uncollected free space. This pre-configures the log structured storage to more efficiently receive the source data. In another embodiment, the host may consult the directory to determine whether the specified logical unit already exists, and only if so, proceed to direct re-classification of the storage space as uncollected free space. In another embodiment, the host may blindly issue a “space release” instruction for the specified logical unit, which is ignored by the storage controller if the logical unit does not already exists in storage. After pre-configuration, the host instructs the storage controller to write the source data to the log structured storage. The storage controller performs the write, and also changes the directory to classify the storage space now occupied by source data as space-in-use.
摘要翻译：通过预配置目标存储，将源数据更有效地复制到日志结构化目标存储。本发明可以在包括主机，存储控制器和目标存储器的系统中实现。主机维护一个目录来识别存储数据的逻辑单元，而存储控制器维护将存储空间分类为未收集的可用空间，收集的可用空间或使用空间的记录。首先，主机接收包括源数据和源数据的逻辑单元的指定的输入。作为响应，主机指示存储控制器将包含指定逻辑单元的数据的日志目标存储的任何存储空间分类为未收集的可用空间。这预先配置日志结构化存储以更有效地接收源数据。在另一个实施例中，主机可以咨询目录以确定指定的逻辑单元是否已经存在，并且只有在这样的情况下，才继续直接将存储空间重新分类为未收集的可用空间。在另一个实施例中，主机可以盲目地发出指定逻辑单元的“空间释放”指令，如果逻辑单元不存在于存储器中，则该存储控制器忽略该指令。预配置后，主机指示存储控制器将源数据写入日志结构化存储。存储控制器执行写入操作，还可以更改目录，将现在由源数据占用的存储空间分类为使用空间。
