摘要： For each high-level protocol, a respective mesh of Transmission Control Protocol (TCP) connections is set up for a cluster of server computers for the forwarding of client requests. Each mesh has a respective pair of TCP connections in opposite directions between each pair of server computers in the cluster. The high-level protocols, for example, include the Network File System (NFS) protocol, and the Common Internet File System (CIFS) protocol. Each mesh can be shared among multiple clients because there is no need for maintenance of separate TCP connection state for each client. The server computers may use Remote Procedure Call (RPC) semantics for the forwarding of the client requests, and prior to the forwarding of a client request, a new unique transaction ID can substituted for an original transaction ID in the client request so that forwarded requests have unique transaction IDs.

摘要： A file server system has a cluster of server computers that share access to a file system in shared storage. One of the server computers has primary responsibility for management of access to the file system. In order to reduce the possibility of primary server overload when a large number of the clients happen to concurrently access the same file system, most metadata processing operations are offloaded to secondary server computers. This also facilitates recovery from failure of a primary server computer since only a fraction of the ongoing metadata operations of a primary server computer is interrupted by a failure of the primary server computer. For example, a secondary data mover may truncate, delete, create, or rename a file in response to a client request.

摘要： Interrupts and code threads are assigned in a particular way to the core CPUs of a network file server in order to reduce latency for processing client requests for file access. Threads of the network stack are incorporated into real time threads that are scheduled by a real-time scheduler and executed exclusively by a plurality of the core CPUs that are not interrupted by disk adapter interrupts so that the disk adapter interrupts do not interrupt execution of the network stack. Instances of a storage access driver are hard affinity threads, and soft affinity threads include a multitude of instances of a thread of the file system stack for file access request processing so that file access request processing for a multitude of concurrent file access requests is load balanced over the core CPUs.

摘要： Based on a count of the number of dirty pages in a cache memory, the dirty pages are written from the cache memory to a storage array at a rate having a component proportional to the rate of change in the number of dirty pages in the cache memory. For example, a desired flush rate is computed by adding a first term to a second term. The first term is proportional to the rate of change in the number of dirty pages in the cache memory, and the second term is proportional to the number of dirty pages in the cache memory. The rate component has a smoothing effect on incoming I/O bursts and permits cache flushing to occur at a higher rate closer to the maximum storage array throughput without a significant detrimental impact on client application performance.

摘要： A system for producing multiple concurrent real-time video streams from stored MPEG video clips includes a video server and at least one MPEG decoder array. The decoder array has multiple decoder pairs, each pair having a video switch for switching from one decoder in the pair to the other at a specified time. Switching may occur from a specified Out-point frame to a specified In-point frame, and the specified frames can be any frame type at any location in the group of pictures (GOP) structure. In a preferred construction, the video server has a controller server linked to a series of data mover computers, each controlling one or more respective decoder arrays. The data mover computers use a control protocol to control the decoder arrays, and each decoder uses a data protocol to request data from a respective data mover computer.

摘要： Original-quality MPEG coded video is processed to produce reduced-quality MPEG coded video for trick mode operation by removing non-zero AC DCT coefficients from the 8×8 blocks of I-frames of the MPEG coded video to produce I-frames of reduced-quality MPEG coded video, and inserting freeze frames in the reduced-quality MPEG coded video. Preferably, the coded video is stored in a main file, a fast-forward file and a fast-reverse file. The fast forward file and the fast reverse files contain reduced-quality I frames corresponding to original-quality I frames in the main file. A reading of the main file produces an MPEG transport stream for an audio-visual presentation at a normal rate, a reading of the fast-forward file produces an MPEG transport stream of the audio-visual presentation in a forward direction at a fast rate, and a reading of the fast-reverse file produces an MPEG transport stream of the audio-visual presentation in a reverse direction at a fast rate. Preferably, the files share a volume that includes at least one GOP index associating the corresponding I frames of the files.

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： Access to movies ranging from very popular movies to unpopular movies is managed by configuring sets of data movers for associated movie rankings, reserving data mover local cache resources for the most popular movies, reserving a certain number of streams for popular movies, negotiating with a client for selection of available movie titles during peak demand when resources are not available to start any freely-selected movie in disk storage, and managing disk bandwidth and primary and local cache memory and bandwidth resources for popular and unpopular movies. The assignment of resources to movie rankings may remain the same while the rankings of the movies are adjusted, for example, during off-peak hours. A movie locked in primary cache and providing a source for servicing a number of video streams may be demoted from primary cache to disk in favor of servicing one or more streams of a higher-ranking movie.

摘要： Coded video from an on-line MPEG video encoder is stored as a clip in a video server or is otherwise received in the video server and prepared or used for splicing. In order to reduce apparent frame inaccuracy that may result from the splicing process, the on-line MPEG video encoder and the server are coordinated so that the group-of-picture (GOP) structure in the encoder provides specified In-points and Out-points that are valid and desirable for splicing. An encoder control protocol is also provided for remote control of the on-line MPEG video encoder in order to coordinate the on-line MPEG video encoder with the video server.
