摘要： A file translation system and a physical information and extensions file for an intermediary controller is disclosed. The file translation system that allow a host computer to directly access data from a different host type without moving the actual data. The physical information and extension file provides information concerning the location of data and the file system the host is viewing. The intermediary controller is disposed between a legacy disk controller for an originating host of a first type and an open system host. The intermediary controller emulates a virtual storage device using a virtual device file system, wherein the virtual device file system mapping data stored in a storage device by the originating host to objects in a root directory in the virtual device file system. The physical information and extension file comprising controller information for identifying the intermediary controller and logical device information, as well as any other information needed by an administrator or service technician.

摘要： A disk caching method for an intermediary controller is disclosed. Requests for data blocks are made and then disk caching is performed according to a most expedient cache method. The disk caching method may be performed by asynchronously requesting a data record from both a intermediary controller disk storage and from a intermediary controller cache and using a first received copy of the data record, the first received copy being a copy received first from the intermediary controller disk storage. Alternatively, the disk caching may be performed by searching an intermediary controller cache to determine whether requested data is located in the cache of the intermediary controller, searching a storage device of the intermediary controller to determine whether requested data is located in the storage device of the intermediary controller and retrieving the requested data from a disk controller coupled to the intermediary controller when the requested data is not in the cache or storage device of the intermediary controller. The intermediary controller maintains a cache hit ratio for cache in a disk controller cache and chooses a cache method based upon a comparison of the hit ratio to the threshold. The intermediary controller selects an item to replace in the intermediary controller cache, moves data into the intermediary controller cache, determines whether the hit ratio of the disk controller is greater than the threshold and moves the item into the intermediary controller storage device when the hit ratio of the disk controller cache is greater than the threshold. The intermediary controller discards the item form the cache of the intermediary controller when the hit ratio of the disk controller is not greater than the threshold.

摘要： A plurality of data units with associated timestamps is stored in a time based file system, wherein a timestamp corresponds to a time indicated by a system clock. A time indicated by the system clock is changed while the plurality of data units is being stored. A plurality of epochs is stored in a data structure, wherein an epoch is a period of time between a starting and an ending timestamp selected from the timestamps, and wherein successive epochs have overlapping time periods. The time based file system is reverted to an earlier point in time based on the plurality of epochs stored in the data structure.

摘要： Tokens corresponding to data units written to a rewritable file system are stored, where an ordering relationship is maintained among the tokens, where the ordering relationship is such that a first token corresponding to a first data unit is of a lesser numerical value in comparison to a second token corresponding to a second data unit, and where the first data unit is written at an earlier point in time in comparison to the second data unit. The rewritable file system is reverted to an indicated point in time based on the ordering relationship that is maintained among the stored tokens.

摘要： Provided are a method, system, and article of manufacture for mirroring data between a first site and a second site. Updates to segments of storage at the first site are copied to corresponding segments of storage at the second site. Codes are generated from the segments at the second site and a valid flag is provided for at least one code indicating whether the code for the segment of data is valid. One code is generated from each segment of storage at the first site. An operation is initiated to copy segments from the second site to the first site. A determination is made for segments at the second site as to whether the valid flag for the code for the segment at the second site indicates that the code is valid in response to initiating the copy operation. The valid code for at least one segment in the second site is compared with the code for the corresponding segment at the first site to determine whether to copy the data from the segment at the second site to the first site as part of the copy operation.

摘要： A system and method, employing a data storage device, for providing communication between a plurality of processing units which are respectively unconnected to each other, with the processing units each separately coupled to the data storage device. A data storage device controller coupled to storage interfaces and to a buffer, recognizes “broadcast” commands and any message accompanying the “broadcast” commands, and recognizes “read message” commands, received from the processing units. The controller stores the message accompanying the “broadcast” command in the buffer, and forwards, at the storage interfaces, a “message ready” signal to at least one of the processing units. The processing units then send a “read message” command to the data storage device. The controller responds to a “read message” command at one of the storage interfaces, supplying the message stored in the buffer at the storage interface to the sending processing unit.

摘要： A data storage library subsystem and a method for storing, and maintaining and tracking synchronism between, multiple copies of identifiable data volumes between hosts and a plurality of data storage libraries, and transparent to the hosts. The library controller of each library provides an updatable synchronization token directly associated with each data volume. A plurality of directors are provided, each separate from and coupled to the hosts and each separate from and coupled to each data storage library. Each director responds to ones of separate, partitioned access addresses addressed by the hosts. The responding director supplies each data volume supplied from a host to all of the data storage libraries, and updates each synchronization token directly associated with the supplied data volume. Thus, the directors store duplicate copies of the data volume in the data storage libraries without involvement by the host. The currency of the data volumes are each tracked by means of the directly associated synchronization token, and the synchronization token is not tracked by the host nor is a central tracking database required.
