摘要： A technique of managing data placement involves constructing an active extent list which identifies active extents stored in a storage pool based on a history of extent activity. The technique further involves based on the active extent list, generating preferred extent-tier pairings for extents of a particular LUN slice that are initially stored on a first tier of the pool, the preferred extent-tier pairings matching (i) a first extent of that LUN slice to the first tier and (ii) a second extent of that LUN slice to a second tier of the pool. The technique further involves, based on the preferred extent-tier pairings, maintaining the first extent on the first tier and relocating the second extent from the first tier to the second tier to distribute the first and second extents of that LUN slice across multiple tiers of the pool in accordance with the extent activity history.

摘要： A technique is directed to managing deduplication of extents in a data storage apparatus having processing circuitry and memory which stores the extents (e.g., blocks). The technique involves constructing, by the processing circuitry, a recently written extent list which identifies recently written extents stored within the memory. The technique further involves referencing the recently written extent list to bypass (or skip over) extents identified by the recently written extent list when obtaining a candidate extent for possible deduplication. The technique further involves processing the candidate extent for possible deduplication. Here, by identifying frequently overwritten extents on the recently written extent list, the data storage apparatus is able to easily avoid cycles of deduplicating and subsequently splitting frequently overwritten extents.

摘要： A technique of identifying IO hot spots is performed in a data storage apparatus (e.g., a file server). The technique involves updating, in response to host IO operations which lock ranges of extents prior to accessing the ranges of extents, contents of a lock history database based on the ranges of extents which were locked by the host IO operations. The technique further involves receiving a lock history request. The technique further involves providing, in response to the lock history request, the contents of the lock history database to identify, as the IO hot spots, extents which were locked by the host IO operations.

摘要： A method is used in managing deduplication density. A deduplication density of a data object is determined. The deduplication density is indicated by a number of deduplicated data objects represented by the data object. Based on the deduplication density of the data object, the data object is skipped for applying a deduplicating technique to the data object. An association is created between the data object and another data object. The other data object is used for applying the deduplicating technique where contents of the other data object are identical to contents of the data object.

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.

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。
