摘要： A physical address extension feature maps multiple virtual memory spaces to an extended physical memory. A virtual space manager dynamically allocates pages of the physical memory to respective virtual spaces. The virtual space manager responds to a request from an application for allocation of a page of physical memory by returning a cookie indicating the allocated page. The virtual space manager responds to a request including the cookie by switching virtual address translation to the virtual memory space including the indicated page. The cookie is used to access a cookie cache of state information on the last page of virtual memory having been mapped into physical memory. For example, segments of the page store block map entries for snapshot copies, and the cookie cache caches the last-accessed values of the block numbers and their location within the page.

摘要： A data storage system maintains a production dataset supported by a clone volume, and multiple snapshot datasets supported by respective save volumes in a snapshot queue. In order to instantaneously restore the production dataset with the state of any specified snapshot, the data storage system responds to requests for read/write access to the production dataset by reading from the specified snapshot dataset and writing to the production dataset. The data storage system keeps a record of data blocks that have been modified by writing to the production dataset. The data storage system initiates a process of copying data blocks from the specified snapshot dataset to the production dataset if the record of the data blocks indicates that the data blocks have not yet been modified by writing to the production dataset.

摘要： A file server maintains a production file system supported by a clone volume, and multiple snapshot file systems supported by respective save volumes in a snapshot queue. Before a data block is modified for the first time after creation of the youngest snapshot, the data block is copied from the clone volume to the save volume of the youngest snapshot. A bit map indicates the blocks that have already been copied, and a block map shows the save block address for each corresponding clone block address. When a new snapshot is created, the bit and block maps are converted to a hash index that is kept linked to the save volume of what had been the youngest snapshot. When other than the oldest snapshot file system is deleted, the respective save volume is retained as a hidden object until it becomes the oldest save volume.

摘要： In an asynchronous remote copy system, a primary site keeps a list of data blocks for which changes have been made to a primary file system and transmitted to a secondary file system at a secondary site. When the primary site becomes inoperative, the secondary site begins read/write access to the secondary file system and keeps a snapshot copy of the restart point. Once the primary site becomes operative, the primary file system is restored to the state of the secondary file system at the restart point by using the list of data blocks for obtaining from the snapshot copy the data of the blocks for which changes had been made to the primary file system after the restart point. Then the primary file system is synchronized to the secondary file system, and read/write access is switched back from the secondary file system to the primary file system.

摘要： A method is used in allocating blocks in storage systems. A block allocation request is received for a file of a file system. The block allocation request includes a data block allocation request and an indirect block allocation request. A type of the file is determined. A cylinder group is selected from a set of cylinder groups for allocating an indirect block based on the block allocation request. A set of data blocks is reserved for allocating a data block based on the type of the file.

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.

摘要： One embodiment of the invention relates to the transfer of content between a host computer that issues OAS access requests and a block I/O storage system. Specifically, a host computer may issue an access request for a content unit that identifies the content unit is an object identifier. The request may be received by a second server, which may determine the block address(es) on the block I/O storage system at which the content unit is stored. A request may then be sent to the block I/O storage system to retrieve the content stored at the requested block address(es) and the block I/O storage system may return the content.

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.
