Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: MPEG coded video data includes groups of pictures (GOPs). Each group of pictures includes one or more I-frames and a plurality of B- or P-frames. To produce an MPEG slow-forward coded video stream, the coding type of each frame in the MPEG coded video data is identified, and freeze frames are inserted as a predefined function of the identified coding type and as a predefined function of a desired slow down factor. In a preferred implementation, for a slow-down factor of n, for each original I- or P-frame, (n−1) backward-predicted freeze frames are inserted, and for each original B-frame, (n−1) copies of the original B-frames are added, and a selected amount of padding is added to each copy of each original B-frame in order to obtain a normal play bit rate and avoid video buffer overflow or underflow.

Abstract: 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 iSCSI 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.

Abstract translation: 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iSCSI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。

Abstract: An airborne obstacle collision avoidance apparatus which includes an object sensor for sensing objects within a field of view of the aircraft and an aircraft navigation system for navigating the aircraft through space. The apparatus also includes a signal processor for receiving data from both the object sensor and the aircraft navigation system, for generating map data of the objects within the field of view of the aircraft, for dynamically changing the map data as the aircraft moves through space and for determining the probability that the aircraft is on a collision course with respect to each sensed object. The apparatus further includes an alarm which is activated when the signal processor determines that there is a high probability that the current aircraft flight direction is on a collision course with respect to a sensed object.

Abstract: Techniques are provided for storing files in a parallel computing system based on a user-specified parser function. A plurality of files generated by a distributed application in a parallel computing system are stored by obtaining a parser from the distributed application for processing the plurality of files prior to storage; and storing one or more of the plurality of files in one or more storage nodes of the parallel computing system based on the processing by the parser. The plurality of files comprise one or more of a plurality of complete files and a plurality of sub-files. The parser can optionally store only those files that satisfy one or more semantic requirements of the parser. The parser can also extract metadata from one or more of the files and the extracted metadata can be stored with one or more of the plurality of files and used for searching for files.
