    摘要： A method, computer program product, and data processing system for continuously writing new data to a redundant array of independent storage devices without interrupting the writing of new data to the array to reconstruct missing data from a failed device or failed media is disclosed. A fault-tolerance scheme using multiple independent parity values is used to record data to the array. In the event that one of the volumes in the array fails, the remaining volumes continue being written to, but with fewer data or parity values being employed. The failed volume can then be reconstructed following the completion of writing the media set currently being written.

    摘要： A communication system permitting temporary connections for specific, predictable data transfer performance is presented. The communication system includes a requesting computer system, a responding computer system, and communication paths for establishing connections between the requesting computer system and the responding computer system. The requesting computer system can establish a temporary initial control connection with the responding computer system through a first communication path. A temporary negotiating connection is established with the responding computer system. Data transfer characteristics are negotiated with the responding computer using the temporary negotiating connection. A temporary data connection is established through a set including at least one communication path based on the negotiated data transfer characteristics, the set not including the first communication path.

    摘要： A method is described which provides various new data storage system capabilities by using data storage structures within industry standard (or other pre-existing) formats used with data recording devices employing removable media. The data storage structures used by the present method comprise formats which contain regions previously marked as "contents of this region are not of interest" or marked as "no data was recorded within this region". These data storage structures are thus transparent to present data recording devices so as not to disrupt their data processing functions. However, the data storage structures are available to be used by new data recording devices (or old devices that have been updated) so that new data embedded therein may be used to enhance the functionality of the system which utilizes the data storage structures. The types of embedded data may include ECC (error correction codes), tape position information, audit information, security information, mount history, media defect history, authentication notation, generation-identification notation, etc.

    摘要： This system makes use of a tape cassette helical scan tape transport and 3480-type magnetic tape cartridge as the data storage media. The merging of these two incompatible elements is accomplished by the use of a novel interface that implements a "virtual tape cassette" using a tape cartridge in a manner that makes this media compatible with the tape transport. The virtual tape cassette is implemented by providing a takeup reel positioned with the magnetic tape cartridge in a relationship that substantially matches the format of a magnetic tape cassette. A short tape threading arm is used to retrieve the leader block from the tape cartridge and thread the magnetic tape over a short tape threading path to the takeup reel. Once the tape is affixed to the takeup reel, the helical scan tape guide arms transport the length of tape that is now exposed between the tape cartridge and the takeup reel to the rotary heads.

    摘要： The removable media management system operates with a manual, an automated, or a combination of subsets of manual and automated library system to store and retrieve media cartridges for an associated plurality of drive elements. This system enables the use of a plurality of types of media within the single monolithic cartridge library system and a corresponding plurality of drive elements associated with said library system. Thus, each drive element has associated therewith a number of object storage locations within the library system which contains media of a form and content that matches the drive element. The removable media management system maps the correspondence between object storage location, media type, designated drive element in a manner such that the single library is partitioned into subsets for the user, i.e., the removable media management system provides the capability to define subsets of media types which have consistent mechanical and electrical characteristics, but can vary in data management attributes. This enables the user to transition to another media on an incremental basis, since a single drive element can be added to the library and associated media added as needed without displacing the embedded base (independent of vendor) of installed media handling processes or software or equipment or requiring significant modification to these.

    摘要： A data storage system for storing data for a host processor includes physical data storage devices each having data storage attributes and an outboard storage manager. The outboard storage manager is operable with the physical data storage devices for presenting to the host processor a virtual data storage image having a desired data storage attribute for a particular data storage application by organizing the physical data storage devices in an arrangement suitable for providing the desired data storage attribute irrespective of the data storage attributes of the physical data storage devices such that the combined physical data storage device arrangement emulates the virtual data storage image. The outboard storage manager is operable to transfer data between the host processor and the organized physical data storage device arrangement via the virtual data storage image.

    摘要： A method and apparatus for achieving compatibility between data storage devices having differing read-write capabilities is disclosed. A track imaging buffer is provided where data can be re-sequenced for optimization of performance of the data storage device into which a recorded medium is loaded. The track imaging buffer is employed whenever a medium bearing data in a format other than the native read-write format of the data storage device is loaded into the device or whenever it is desired to generate a medium for use by a storage device having a native format different from the device in which the medium is to be generated.
