摘要： A method is used in managing global metadata caches in data storage systems. Space is allocated in a memory of a data storage system to a global metadata cache which is configured to store metadata objects for a plurality of different file systems responsive to file system access requests from the plurality of different file systems. A metadata object associated with a file of a file system of the plurality of different file systems is stored in the global metadata cache. The metadata object is accessed by a plurality of different versions of the file.

摘要： One embodiment of the invention is directed to providing a single instance storage capability in a content addressable computer system that stores content units in a time-based directory structure. Another embodiment is directed to managing access to content units that do not include a timestamp in their content addresses, in a time-based directory structure. A further embodiment is directed to accessing replicated content units stored on a computer, based on a time of replication. A further embodiment is directed to employing a bitmap in a time-based directory structure which may be used to indicate whether any content units stored during a specified time range are stored in the directory structure.

摘要： One embodiment is directed to a computer system that includes primary and secondary storage systems. When a request to store a content unit is received, it may be determined whether to store the content unit on the primary storage system or the secondary storage system. In another embodiment, a computer may store information relating to an action to be performed in one of the directories of a file system that corresponds to a period of time. When the period of time to which the directory corresponds arrives, the action may be performed. In another embodiment, a content unit stored on a primary storage system may be copied to a secondary storage system in a computer system. After the content unit has been copied, the secondary storage system may send a delete request to the primary storage system to delete the content unit from the primary storage system.

摘要： One embodiment of the invention is directed to the containerization of content units that are accessed using an identifier. Applicants have appreciated that file systems sometimes impose limits on the number of files that may be stored therein that are too restrictive. Thus, in one embodiment, multiple content units may be stored in a single file, called a container file, in a file system. Each content unit may have an identifier associated with it. When an accessing entity requests access to a previously-stored content unit and provides the identifier for the content unit, the identifier may be used to locate the container file in which the content unit is stored.
摘要翻译：本发明的一个实施例涉及使用标识符访问的内容单元的容器化。申请人已经意识到，文件系统有时限制可能存储在其中的太多限制的文件数量。因此，在一个实施例中，多个内容单元可以被存储在文件系统中的被称为容器文件的单个文件中。每个内容单元可以具有与其相关联的标识符。当访问实体请求访问先前存储的内容单元并提供内容单元的标识符时，可以使用该标识符来定位其中存储内容单元的容器文件。

摘要： A method is used in managing active-active mapped logical volumes. A mapped logical volume is created. The mapped logical volume includes first and second mapped logical volumes. Ownership of the first mapped logical volume resides with a first storage processor of a storage system and ownership of the second mapped logical volume resides with a second storage processor of the storage system. The mapped logical volume is managed. An access to the mapped logical volume is provided to the first and second storage processors.

摘要： Based on a count of the number of dirty pages in a cache memory, the dirty pages are written from the cache memory to a storage array at a rate having a component proportional to the rate of change in the number of dirty pages in the cache memory. For example, a desired flush rate is computed by adding a first term to a second term. The first term is proportional to the rate of change in the number of dirty pages in the cache memory, and the second term is proportional to the number of dirty pages in the cache memory. The rate component has a smoothing effect on incoming I/O bursts and permits cache flushing to occur at a higher rate closer to the maximum storage array throughput without a significant detrimental impact on client application performance.
摘要翻译：基于高速缓冲存储器中脏页数的计数，脏页以高速缓冲存储器中的脏页数的变化率成比例的速率从高速缓冲存储器写入存储阵列。例如，通过将第一项添加到第二项来计算所需的刷新速率。第一项与高速缓冲存储器中脏页数的变化率成比例，第二项与高速缓冲存储器中的脏页数成比例。速率组件对传入的I / O突发具有平滑效果，并允许高速缓存刷新以更高的速率发生，更接近最大存储阵列吞吐量，而不会对客户端应用程序性能造成重大的不利影响。

摘要： Aspects of the invention relate to creating a snapshot of a file system on an OAS system. A snapshot of a file system is an image of a file system at a particular point in time. A snapshot of a file system may be used to restore the file system to its state at the time of creation of the snapshot in, for example, situations where the file system has become corrupted.
摘要翻译：本发明的方面涉及在OAS系统上创建文件系统的快照。文件系统的快照是特定时间点的文件系统的映像。可以使用文件系统的快照来将文件系统恢复到在例如文件系统已经损坏的情况下创建快照时的状态。
