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： Described are techniques for managing data in a data storage system. While the data storage system is operating in a first mode, portions of cached write data not yet destaged to a data storage device are copied from the volatile memory cache to a first area in a flash-based memory. In response to a vault operation event, the data storage system operates in a second mode in which all remaining portions of cached write data from the volatile memory cache not currently included in the first area are copied to a second area of the flash-based memory.

摘要： Described are techniques for processing a data storage configuration request for an application A first user level of a plurality of user levels at which said data storage configuration request is made is determined. One or more rule sets defining mappings between different ones of said plurality of user levels are provided. Each of the different user levels is associated with a different level of abstraction with respect to processing performed in the data storage system for implementing the data storage configuration request. One of the rule sets is selected in accordance with the application, a data service requested in said data storage configuration request, and a user grouping including said plurality of user levels. The data storage configuration request is serviced using rules of the selected rule set.

摘要： A protocol is provided for allocating file locking tasks between primary and secondary data mover computers in a network file server. When there is frequent read access and infrequent write access to a file, a primary data mover grants read locks to the entire file to secondary data movers, and the secondary data movers grant read locks to clients requesting read access. When write access to the file is needed, the read locks to the entire file are released and the read locks granted to the clients are released or expire or are demoted to non-conflicting byte range locks managed by the primary data mover. Concurrent read and write access to the same file is then managed by the primary data mover.

摘要： A file system is migrated from a source file server to a target file server in a data network while permitting clients to have concurrent read/write access to the file system. The target file server issues directory read requests and file read requests to the source file server in accordance with a network file access protocol to transfer the file system from the source file server to the target file server. Concurrent with the transfer of the file system from the source file server to the target file server, the target file server responds to client read/write requests for access to the file system. In a preferred embodiment, the target file server maintains a hierarchy of on-line nodes off-line nodes. The online nodes represent file system objects that have been completely migrated, and the offline nodes representing file system objects that have not been completely migrated. The target file server executes a background process that walks through the hierarchy in order to migrate the objects of the offline nodes. When an object has been completely migrated, the target file server changes the offline node for the object to an online node for the object.
摘要翻译：文件系统从源文件服务器迁移到数据网络中的目标文件服务器，同时允许客户端对文件系统进行并行读/写访问。目标文件服务器根据网络文件访问协议向源文件服务器发出目录读取请求和文件读取请求，以将文件系统从源文件服务器传输到目标文件服务器。同时将文件系统从源文件服务器传输到目标文件服务器，目标文件服务器响应客户端读/写请求访问文件系统。在优选实施例中，目标文件服务器维护在线节点离线节点的分层。在线节点表示已经完全迁移的文件系统对象，并且表示尚未完全迁移的文件系统对象的脱机节点。目标文件服务器执行后台进程，以便遍历层次结构，以便迁移脱机节点的对象。当对象已被完全迁移时，目标文件服务器将对象的脱机节点更改为对象的联机节点。

摘要： A data processing system includes compute nodes, at least one metadata server, iSCSI storage access servers, and data storage devices. The metadata server services requests from the compute nodes for file mapping information identifying iSCSI LUNs and logical blocks of file data. The storage access servers service iSCSI I/O requests from the compute nodes, and report server loading to the metadata server. A Gigabit Ethernet IP network transfers read and write data between the compute nodes and the storage access servers. The storage access servers are linked to the data storage devices for parallel access to iSCSI LUNs of the file data in the data storage devices. The metadata server is programmed for server load balancing by indicating to the compute nodes respective ones of the storage access servers that should be used for access to the iSCSI LUNs.

摘要： A read-write access to a file in a file server includes an initial metadata access step, an asynchronous read or write of file data, and a metadata commit step. In order to parallelize access to a range locking database, an inode and indirect file block mapping database, and a pre-allocation data base, operations are pipelined within the metadata access step and also within the metadata commit step. The pipelined operations within the metadata access step include a first stage of range locking, a second stage of reading block mapping metadata, and a third stage of reading and updating a pre-allocation map for write access. The pipelined operations within the metadata commit step include a first stage of releasing range locks, a second stage of accessing old block metadata for write access, and a third stage of updating metadata and flushing the pre-allocation map for write access.
