摘要： Methods, systems, and computer program products for providing access to shared storage by a plurality of nodes are disclosed. According to one method, at a node of a plurality of nodes sharing access to a disk array, an application input/output (I/O) operation and whether sufficient space in the disk array has been mapped at the node for the I/O operation are detected. In response to detecting that sufficient space in the disk array has not been mapped at the node for the I/O operation, a map for the I/O operation including physical disk access information is requested and obtained from a server. The physical disk access information included within the map for the application I/O operation obtained from the server is used to perform the I/O operation by accessing the disk array without intervention by the server.

摘要： File system cells are linked together to form a meta file system that appears to a user or application program to be a single file system. The meta file system permits concurrent access by multiple processors in a file server wherein each file system cell is managed by a respective one of the processors. The file server responds to a directory access request by returning a file handle containing a file system cell ID and a pointer to a file in the file system cell. The file server responds to a subsequent file access request including the file handle by extracting the file system cell ID and the pointer to the file, searching a routing table for an entry having a file system cell ID matching the file system cell ID extracted from the file handle, and routing the request to the processor managing the file system cell.

摘要： A method is used in managing data on data storage systems. Rules are defined for candidate data unit selection. The rules are automatically executed on a primary data storage system to examine data units on the primary data storage system. The rules are applied to the data units. A data unit is identified that matches the rules and the identified data unit is migrated. The identified data unit is copied from the primary storage system to a secondary storage system. The identified data unit on the primary storage system is replaced with metadata. the data storage space in the primary storage system corresponding to the identified data unit is freed up.

摘要： Servers in a storage system store a nested multilayer directory structure, and a global index that is an abstract of the directory structure. The global index identifies respective portions of the directory structure that are stored in respective ones of the servers, and the global index identifies paths through the directory structure linking the respective portions. Upon performing a top-down search of the directory structure in response to a client request and finding that a portion of it is offline, the global index is searched to discover portions of the directory structure that are located below the offline portion. The global index may also identify the respective server storing each of the respective portions of the directory structure, and may indicate whether or not each of the respective portions of the directory structure is known to be offline.

摘要： A data storage system receives sets of the revisions such that each set of revisions changes the dataset from one consistent state to another. Each set of revisions is processed in a write-selected phase followed by a read-selected phase. In the write-selected phase, the revisions in each set are written to a buffer and processed to produce a directory of the set of revisions. In the read-selected phase, the revisions are read from the buffer and integrated into the dataset. When one set of revisions is in the read-selected phase, the next set of revisions is in the write-selected phase. To permit uninterrupted read-only access to a consistent state of the dataset, the data storage system responds to a request for reading specified data on a priority basis by first accessing the directory of the read-selected revisions to determine whether the specified data are in the read-selected set of revisions, and if so, the specified data are read from the read-selected set of revisions, and if not, the specified data are read from the dataset. In a preferred implementation, the sets of revisions are alternately written to either a first buffer or a second buffer, and processing of each set of revisions is switched from the write-selected phase to the read-selected phase by switching between the two buffers.

摘要： In a synchronous remote mirroring system, as a host computer writes data to primary storage in a primary data storage system, remote copy data is transferred from the primary data storage system to a secondary storage system in which secondary storage is maintained as a remote mirror of the primary storage. The primary data storage system performs data reduction upon the remote copy data prior to transmitting the remote copy data in a reduced to the secondary data storage system. The secondary data storage system returns an acknowledgement of receipt of the remote copy data upon receipt of the remote copy data in the reduced form, and later reverses the data reduction upon the remote copy data in the reduced form to produce data written to the secondary storage to maintain the secondary storage as the remote mirror of the primary storage.

摘要： In a data processing system, a first processor pre-allocates data blocks for use in a file system at a later time when a second processor needs data blocks for extending the file system. The second processor selectively maps the logical addresses of the pre-allocated blocks so that when the pre-allocated blocks are used in the file system, the layout of the file system on disk is improved to avoid block scatter and enhance I/O performance. The selected mapping can be done at a program layer between a conventional file system manager and a conventional logical volume layer so that there is no need to modify the data block mapping mechanism of the file system manager or the logical volume layer. The data blocks can be pre-allocated adaptively in accordance with the allocation history of the file system.
摘要翻译：在数据处理系统中，当第二处理器需要用于扩展文件系统的数据块时，第一处理器在稍后的时间预分配用于文件系统的数据块。第二处理器选择性地映射预分配块的逻辑地址，使得当在文件系统中使用预先分配的块时，改进了盘上的文件系统的布局，以避免块散射和增强I / O性能。所选择的映射可以在常规文件系统管理器和常规逻辑卷层之间的程序层完成，使得不需要修改文件系统管理器或逻辑卷层的数据块映射机制。数据块可以根据文件系统的分配历史自适应地预分配。

摘要： An improved policy enforcement architecture includes several components that improve the performance of policy enforcement in a hierarchical storage environment. A File System Query instruction permits a richer set of queries to be expressed by a policy engine, thereby permitting more complex policies to be implemented with ease. The File System result is generated at the file server, and only files of interest are forwarded to the policy engine. The file system query advantageously may be applied against a pre-generated index having one more characterizing attributes to further reduce the processing required to retrieve policy data. An Index Build instruction, added to a programming interface, allows a policy engine generate the characterizing indices in advance of use. Index maintenance techniques maintain consistency between the index and the file system to ensure that the policy can be enforced using accurate file information.

摘要： File system cells are linked together to form a meta file system that appears to a user or application program to be a single file system. Each file system cell may have a conventional file system format, and can be indistinguishable from a conventional file system except for information, such as directory entry attributes, indicating one or more links to other file system cells. These external links may include direct links that are hidden from the user or application program and define a hierarchy of the meta file system cells, and indirect links that appear in the user-visible file system. The meta file system substantially reduces crash recovery time because each file system cell functions as a consistency unit that can be repaired only if needed. The meta file system also permits the file system cells to be accessed concurrently by multiple processors in a file server.

摘要： Accordingly a method and interface allows an attribute data base used by an Information Manager to be quickly populated and accurately maintained. A single Bulk Attribute Retrieval Request triggers the primary storage device to collect object attribute information. The method allows for selective collection of objects and attributes by providing filters and attribute lists in the Requests. The Request may be used to provide an incremental scan with appropriate time stamp filtering. In addition, the size of the results can be controlled by the IM by eliminating attributes that are not of interest to the IM. The Request is advantageously issued over a FileMover interface, which is an HTTP connection, and encoded in XML, allowing the IM to easily customize the Request as desired.
