    摘要： To permit multiple unsynchronized processors to update the file-modification time attribute of a file during concurrent asynchronous writes to the file, a primary processor having a clock manages access to metadata of the file. A number of secondary processors service client request for access to the file. Each secondary processor has a timer. When the primary processor grants a range lock upon the file to a secondary, it returns its clock time (m). Upon receipt, the secondary starts a local timer (t). When the secondary modifies the file data, it determines a file-modification time that is a function of the clock time and the timer interval, such as a sum (m+t). When the secondary receives an updated file-modification time (mp) from the primary, if mp>m+t, then the secondary updates the clock time (m) to (mp) and resets its local timer.

    摘要： A storage object such as a virtual disk drive or a raw logical volume is contained in a UNIX compatible file so that the file containing the storage object can be exported using the NFS or CIFS protocol and shared among UNIX and MS Windows clients or servers. The storage object can be replicated and backed up using conventional file replication and backup facilities without disruption of client access to the storage object. For client access to data of the storage object, a software driver accesses the file containing the storage object. For example, a software driver called a virtual SCSI termination is used to access a file containing a virtual SCSI disk drive. Standard storage services use the SCSI over IP protocol to access the virtual SCSI termination. An IP replication or snapshot copy facility may access the file containing the virtual SCSI disk drive using a higher-level protocol.

    摘要翻译： 存储对象（如虚拟磁盘驱动器或原始逻辑卷）包含在UNIX兼容文件中，以便可以使用NFS或CIFS协议导出包含存储对象的文件，并在UNIX和MS Windows客户端或服务器之间共享。 可以使用传统的文件复制和备份功能来复制和备份存储对象，而不会中断对存储对象的客户端访问。 为了客户机访问存储对象的数据，软件驱动程序访问包含存储对象的文件。 例如，称为虚拟SCSI终端的软件驱动程序用于访问包含虚拟SCSI磁盘驱动器的文件。 标准存储服务使用SCSI over IP协议来访问虚拟SCSI终端。 IP复制或快照复制功能可以使用更高级别的协议访问包含虚拟SCSI磁盘驱动器的文件。

    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： For migration or de-duplication of a file system having a large number of files, a utility program traverses the file system to create a log of file-specific information about the file system. For identification of duplicates, the utility program produces a signature for each file. Respective instances of the utility program are started on multiple nodes upon which the file system is mounted. A fully qualified pathname is compiled during transfer of the log to a database. Multiple databases can be produced for the file system such that each database contains the file-specific information for a specified range of inode numbers. The database also maintains classification state for each file. For example, for a migration or replication process, the classification state identifies whether or not the file has been untouched, copied, linked, secondary-ized, source deleted, or modified.

    摘要： An intelligent network client has the capability of accessing a first network server in accordance with a first high-level file access protocol, and responding to a redirection reply from the first network server by accessing a second network server in accordance with a second high-level file access protocol. For example, the intelligent network client can be redirected from a CIFS/DFS server to a NFS server, and from an NFSv4 server to a CIFS server. Once redirected, the intelligent network client performs a directory mounting operation so that a subsequent client access to the same directory goes directly to the second network server. For example, the first network server is a namespace server for translating pathnames in a client-server network namespace into pathnames in a NAS network namespace, and the second network server is a file server in the NAS network namespace.

    摘要： A namespace server translates client requests for access to files referenced by pathnames in a client-server namespace into requests for access to files referenced by pathnames in a backend NAS network namespace. The namespace server also translates between different file access protocols. The namespace server may change the translation of a client-server network pathname from an old backend NAS network pathname to a new backend NAS network pathname for file migration without disruption to client access during file migration for load balancing or for a more appropriate service level. Client access can also be routed automatically and transparently to replicas in case of server or site failures. The namespace server may create the appearance of a virtual file system that contains multiple physical servers, a virtual share that contains physical shares from different servers, directories that contain files on different servers, and files that contain data from files on different servers.

    摘要： Metadata for splicing of an encoded digital motion video stream (such as an MPEG Transport Stream) is prepared in real time while recording at the encoding bit rate and faster than encoded bit rate for off line encoding independent of the bit rate and mechanisms for ingestion of the data stream into data storage. Preprocessing is performed during a metered file transfer protocol (FTP) and includes pseudo real-time encoding. The preprocessing includes Group of Pictures (GOP) level pre-processing of splicing In Points and results in an intimate linkage between metadata and the file system in which the video data is stored. The preferred file system enables access to metadata in parallel to writing the data on disk. The pre-processing is performed simultaneous to writing the data to the disk using a carousel type buffer mechanism.

    摘要： To produce a paused MPEG coded video stream from an original MPEG coded video stream, an I frame is extracted from the original stream, and a Group of Pictures for a “pause” (a pause GOP) is constructed containing the extracted I frame, some “frozen” frames, and padding. Each “frozen” frame is a P frame that repeats the I frame. When a pause is requested in the original stream, a seamless transition is made from the I frame to the pause GOP, and the pause GOP is played in a loop until a resume is requested. To resume, the pause GOP is completed and a seamless transition is made to continue in the original stream from the I frame where the pause had begun.
