    摘要: Facilitating access to data in a network, is provided. One implementation involves maintaining a scalable multi-node file system cache in a local cluster file system, and caching file data in a cache by fetching file data on demand from a remote cluster file system into the local cached file system over the network. The local file data corresponds to file data in the remote cluster file system. Upon disconnection from the remote cluster file system, all file operations are supported at the cache. Then, upon reconnection to the remote cluster file system over the network, the remote cluster file system is synchronized with the information cached in the cache during the disconnection even in the presence of failures.

    摘要: Space is allocated on data storage devices in proportion to weights associated with the storage devices. The weights can be dynamically adjusted at any time in order to accommodate changes in the system and to better utilize the storage devices. The technique used to perform the allocating is independent of the weights used by the allocating. Further, the allocation technique can accommodate general purpose data streams having varying lengths and/or varying access patterns, as well as special purpose data streams, such as video streams.

    摘要: A storage gateway is employed as part of a security enhancing protocol in a data processing system which includes at least one metadata controller node and at least one application node which is granted a time limited access to files in a shared storage system. The gateway is provided with information as to data blocks to which access is to be allowed and also with information concerning the duration of special access granted to a requesting application node. This insures that metadata cannot be improperly used, changed or corrupted by users operating on an application node.

    摘要: A system, method and computer readable medium for providing a standby file system with snapshot feature is disclosed. A first snapshot of a primary file system is generated. Next, a standby file system restores the first snapshot of the primary file system in the standby file system and a snapshot of the standby file system is taken. Then, a second snapshot of the primary file system is taken and a data set capturing the differences between the first snapshot of the primary file system and a previous data set of the primary file system is generated. Subsequently, the data set is applied to the standby file system. Upon unavailability of the primary file system, the standby file system is initialized as the new primary file system. Upon recovery of the old primary file system, the old primary file system is initialized as a new standby file system.

    摘要: A means and method for comparing an incoming sequential string of digitally encoded characters from a database stored in a conventional memory against a pattern with an arbitrary number of elements, comprising specified characters or character types (alphabetic, numeric, delimiter, etc.) or tokens to indicate the matching of a specified or arbitrary number of input characters, is disclosed. The system comprises a number of digital machines, sequenced by control words fetched from their memories. The control words may indicate the current input character or character type of interest for each machine, the address of the potential next control word of the machine, a flag indicating the successful completion of a match, and other control fields. If the input character matches the character or type of interest, the machine's next control word will be that specified by the current control word, and optionally the next control word of one or more of the other machines will be forced to an address specified in the current control word. By properly specifying the control words in each machine the input character string can be compared against an arbitrary number of pattern elements, limited only by the ability to map the elements into the control word memories of the available machines.
