摘要： A data storage system has at least three data storage disks and a plurality of processing nodes in communication with the data storage disks. Each of the processing nodes shares access to the data storage disks, and each of the processing nodes includes a distributed lock manager that allows or denies access to selected stripes of data storage sectors on any of the data storage disks. Each of the processing nodes includes an interface to a private communication link to a single one of a plurality of host operating systems.

摘要： A recovery method for use in a data storage system in which a plurality of data storage devices are connected to each of two communication paths. A switch may route requests to either of the two communication paths. With one data storage controller in communication with the data storage devices over a first path and a second data storage controller in communication with the data storage devices over a second path, upon detection of a malfunction on the first path, a data storage controller may request access to the other path. Thereafter, the controller may be switched into connection with the remaining operable path so as to share that path with the other controller.

摘要： A recovery method and fail-over switch for use in a data storage system in which a plurality of data storage devices are connected to each of two communication paths. The switch may route requests to either of the two communication paths. Switching may be accomplished by two fail-over switches connected to each other and each in connection with one of the two communication paths. With one data storage controller in communication with the data storage devices over a first path and a second data storage controller in communication with the data storage devices over a second path, the fail-over switches may be used upon detection of a malfunction on one path to switch a controller into connection with the remaining operable path so as to share that path with the other controller.

摘要： A method for providing on-line replacement of a module which is at a specified position in an array of modules connected to a common control processor so that all other modules in the array can continue operating during the replacement operation. When the module is removed an indication is provided to the control processor showing that removal has occurred and identifying the position thereof. When the replacement has occurred an indication thereof is provided to the control processor, the replacement module is tested, and the state of the replacement module is updated to place it in the same state it would have been in if it had not been replaced.

摘要： A system and method for storing data, the system having one or more storage devices, caches data from a sender into a first random-access structure located in a first cache level, caches data from the first cache level into a log structure located in a second cache level, and stores data from CL into a second random-access structure located in a storage level, wherein CL is the first cache level or the second cache level. In further embodiments of the invention, the second cache level caches in the log structure parity data for the data cached in the log structure. In a still further embodiment of the invention, the storage level stores in the second random-access structure parity data for the data stored in the second random-access structure.

摘要： A method for handling data in a plurality of data storage disks having user data sectors and corresponding parity sectors, the method being used when the disks are being operated in a degraded mode wherein data in sectors of an inoperative user data disk are reconstructed from data in the corresponding sectors of the other user data disks and the corresponding parity entry. The reconstructed user data in a user data sector of the inoperative disk is written into the corresponding parity sector in place of the parity entry therein, before any new data is written into the corresponding sector of an operative disk. Information identifying the inoperative disk is written into a specified identification region of the parity disk to indicate that such operation has occurred. The new data is then written into the corresponding sector of the operative disk.

摘要： A system and method for cleaning a log structure, the log structure including one or more segments, each segment including live data, orders the one or more segments into a hot list according to age, with the youngest segment at the beginning of the hot list and the oldest segment at the end of the hot list, the youngest segment being the most recently used segment and the oldest segment being the least recently used segment, pushes one or more of the oldest segments in the hot list to a cleaning matrix, the cleaning matrix grouping segments according to age and percent of live data in the segment, traverses the cleaning matrix looking for a segment, determines whether enough live data has been found to write a complete segment, sequentially repeats the previous two processes until enough live data has been found to write a complete segment, reads data from the one or more found segments, and writes the read live data into an unused segment.

摘要： A method for handling data in a plurality of data storage disks having user data sectors and corresponding parity sectors, the method being used when the disks are being operated in a non-degraded or a degraded mode wherein a non-volatile RAM is used in an array control processor which controls the operation of such disks. When new data is to be written into the array, the non-volatile RAM stores information identifying the array, the starting sector into which data is to be written and the number of sectors to be used for writing the new data so that parity and data entries in corresponding sectors can be matched when a power failure occurs. Further, when opening a new array, the data and parity entries in corresponding sectors can be matched and verified, the operation for such matching being performed in between other operations that are being performed by the control processors (i.e., in the "background" thereof).
