摘要： As disclosed herein a computer system for secure database backup and recovery in a secure database network has N distributed data nodes. The computer system includes program instructions that include instructions to receive a database backup file, fragment the file using a fragment engine, and associate each fragment with one node, where the fragment is not stored on the associated node. The program instructions further include instructions to encrypt each fragment using a first encryption key, and store, randomly, encrypted fragments on the distributed data nodes. The program instructions further include instructions to retrieve the encrypted fragments, decrypt the encrypted fragments using the first encryption key, re-encrypt the decrypted fragments using a different encryption key, and store, randomly, the re-encrypted fragments on the distributed data nodes. A computer program product and method corresponding to the above computer system are also disclosed herein.

摘要： A storage server for efficiently retrieving data from a plurality of disks in response to user access requests. The server comprises a plurality of processors coupled to disjoint subsets of disks, and a custom non-blocking packet switch for routing data from the processors to users. By tightly coupling the processors to disks and employing an application-specific switch, congestion and disk scheduling bottlenecks are minimized. By making efficient use of bandwidth, the architecture is also capable of receiving real-time data streams from a remote source and distributing these data streams to requesting users. The architecture is particularly well suited to video-on-demand systems in which a video server stores a library of movies and users submit requests to view particular movies.

摘要： A method and apparatus for reconstructing lost data from a failed disk drive in a disk array. The disk drive array formed into at least one parity group including data extents divided into data segments and parity segments that are generated from the data segments. The method includes providing access to the array, identifying a failed drive and failed parity group associated with the failed drive, and retrieving the parity segments from operative drives in a parity group containing the failed drive in an instance data is being read from the failed parity group. Parity information is reconstructed for the failed disk drive from the parity segments on the operative disk drives, and data segments of the extent associated with the failed disk drive is reconstructed from the reconstructed parity information, and the parity segments and data segments on the operative disk drives of the failed parity group.

摘要： A method and system for storing a continuous feed of video is provided. According to one aspect of the invention, the continuous feed is encoded in a digital video format to produce a digital data stream. A series of content files is created by repeatedly performing the steps of (1) storing the digital data stream in a current file, and (2) establishing a new file as the current file when the current file satisfies a predetermined condition. If the series of content files contains more than a predetermined amount of the continuous feed, the oldest content file in the series of content files is deleted. Tag information that indicates information about frames contained in the digital data stream is generated. The tag information includes timestamps that indicate timing of frames relative to a beginning of the digital data stream. An initial time value that indicates an absolute time that corresponds to the beginning of the digital data stream. When a request from a client for playback beginning at a specified absolute time is received, the initial time value is subtracted from the specified absolute time to determine a relative time. The tag information is used to identify a location in the digital data stream that corresponds to the relative time. The digital data stream is then transmitted to the client beginning at the location in the digital data stream that corresponds to the relative time.
摘要翻译：提供了一种用于存储视频的连续馈送的方法和系统。根据本发明的一个方面，连续馈送被以数字视频格式编码以产生数字数据流。通过重复执行以下步骤（1）将数字数据流存储在当前文件中，并且（2）当当前文件满足预定条件时，建立新文件作为当前文件，创建一系列内容文件。如果一系列内容文件包含超过预定量的连续馈送，则删除一系列内容文件中最早的内容文件。生成表示包含在数字数据流中的帧的信息的标签信息。标签信息包括指示帧相对于数字数据流的开头的定时的时间戳。指示对应于数字数据流的开始的绝对时间的初始时间值。当接收到从指定绝对时间开始的客户机进行回放的请求时，从指定的绝对时间减去初始时间值以确定相对时间。标签信息用于标识对应于相对时间的数字数据流中的位置。然后，数字数据流从对应于相对时间的数字数据流中的位置开始发送到客户端。

摘要： A data organization scheme for movies stored on a video server. The method utilizes the available bandwidth and space in the I/O system to avoid the data contention in the ATM. Basically, parts of the hot movies are replicated on the server unit. Most of the requests to the hot movie are directed to this unit. But if the server unit can not deliver the required video object within the required time limit (because of the large queue length) the video object is transported from the other server units through the ATM network. All the requests that are fulfilled locally by the server unit will not go through the network. Thus, the traffic through the ATM decreases on the expense of increasing the disk utilization.
