摘要： A system and method for managing data updates by cascading those updates through a virtual copy hierarchy from parent copies to child copies are provided. Virtual copies are created and managed through the use of an instant copy mechanism. Metadata subsets manage both the original data and the copies created by the instant copy mechanism. With an exemplary embodiment of the system and method, changes made to one copy of the data are cascaded to all child copies of the data. In this paradigm not only is the metadata entry for one particular copy changed, but also the corresponding metadata entries of any copies descended from that copy. In an exemplary method, a tree structure is used to maintain a record of all metadata table subsets created by use of an instant copy method. The tree structure can then be searched to find all child copies of a particular copy.

摘要： A data storage system for remote access to stored data. The innovative system uses a storage library to contain magnetic hard disks and automatically replaces the hard disks upon failure, without human intervention. Failed disks are removed from the library by a robot, deposited from the library, upon which time they are further processed for delivery to the manufacturer, or for disposal. Replacement disk drives are accessed by the robot from within the library to replace the removed storage element. The system's robot is not only moving individual storage elements, but also of moving the access cables connecting the storage elements to the external network. Using this capability, the number of access cables is reduced without requiring added human intervention.

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： The control software and hardware in the tape drive control unit creates and manages a header segment at the beginning of the magnetic tape. This header is interposed between a leader portion of the magnetic tape on the 3480-type cartridge and the remainder of the magnetic tape contained therein. This header segment contains two sections, a first of which is a data record directory that is used by the control unit to denote the location of each data record written on to the magnetic tape as well as administrative information associated with the data record. The second section of the header is an administrative information section that contains data relating to the magnetic tape itself. The stream of data records is divided into data segments, a plurality of which comprise a single helical scan track. The helical scan tracks are formed into scan groups and written on the magnetic tape. At least one longitudinal track is written on the magnetic tape coextensive with the helical scan groups to provide data to enable the tape drive to quickly locate data records recorded on the magnetic tape.

摘要： The use of a dynamically mapped virtual memory system permits the storage of data so that each data record occupies only the physical space required for the data. Furthermore, the data storage subsystem manages the allocation of physical space on the disk drives and does not rely on the file extent defined in the count key data format. Data compaction apparatus is provided to remove the gaps contained in the stream of count key data records received from the host processor. A data compression algorithm is then used to compress the received data into a compressed format for storage on the disk drives. It is the compacted, compressed data that is finally stored on the disk drives. Furthermore, any data record received from the host processor absent data in the user data field therein is simply listed in the virtual memory map as a null field occupying no physical space on the disk drives. The data storage control, through its mapping capability, stores the actual data in the minimum physical space required by overcoming the limitations imposed on large form factor disk drives by the use of count key data format data records. However, the data storage subsystem returns this stored data to the host processor in count key data format through a data record reformatting process once the stored compacted compressed data is staged to the cache memory for access by the host processor. The data storage subsystem is operationally independent of the host processor, yet performs as if it were a standard operationally dependent large form factor disk subsystem.
摘要翻译：使用动态映射的虚拟内存系统允许数据的存储，使得每个数据记录仅占用数据所需的物理空间。此外，数据存储子系统管理磁盘驱动器上的物理空间的分配，并且不依赖于以计数密钥数据格式定义的文件大小。提供数据压缩装置以去除从主机处理器接收的计数密钥数据记录流中包含的间隙。然后使用数据压缩算法将接收到的数据压缩成压缩格式，以便存储在磁盘驱动器上。压缩的压缩数据最终存储在磁盘驱动器上。此外，从主机处理器接收到的任何数据记录，其中没有用户数据字段中的数据，在虚拟存储器映射中被简单地列为在磁盘驱动器上不占用物理空间的空字段。通过其映射能力，数据存储控制通过使用计数密钥数据格式数据记录将实际数据存储在克服大尺寸磁盘驱动器上的限制所需的最小物理空间中。然而，一旦所存储的压缩压缩数据被暂存到高速缓冲存储器以供主机处理器访问，数据存储子系统通过数据记录重新格式化过程将该存储的数据以计数密钥数据格式返回到主机处理器。数据存储子系统在操作上独立于主机处理器，但是其作为标准的操作依赖大型磁盘子系统执行。

摘要： The parallel disk drive array data storage subsystem dynamically maps between virtual and physical data storage devices and schedules the writing of data to these devices. The data storage subsystem functions as a conventional large form factor disk drive memory, using an array of redundancy groups, each containing N+M disk drives. The data storage subsystem does not modify data stored in a redundancy group but simply writes the modified data as a new record in available memory space on another redundancy group. The original data is flagged as obsolete. A mapping table is maintained to identify portions of these redundancy groups which contain newly written or modified virtual track instances. These marked virtual track instances are written to backup medium as a background process and the mapping table is updated to clear the flags that identify these virtual track instances as having been modified.
