摘要： A hardware and/or software facility to enable emulated storage devices to share data stored on physical storage resources of a storage system. The facility may be implemented on a virtual tape library (VTL) system configured to back up data sets that have a high level of redundancy on multiple virtual tapes. The facility organizes all or a portion of the physical storage resources according to a common store data layout. By enabling emulated storage devices to share data stored on physical storage resources, the facility enables deduplication across the emulated storage devices irrespective of the emulated storage device to which the data is or was originally written, thereby eliminating duplicate data on the physical storage resources and improving the storage consumption of the emulated storage devices on the physical storage resources.

摘要： A method and system for generating a snapshot in a consistent state is disclosed. The system comprises a host computer, a primary data storage, a data protection unit, and a secondary data storage. The data protection unit monitors a state of an application which is running on the host computer. The data protection unit generates a snapshot of data stored in a primary data storage when the application is in a consistent state, and stores the snapshot on a secondary storage. In the event of a system failure, the data is recovered using the last snapshot.

摘要： A method for synchronizing a secondary volume with a primary volume in a continuous data protection system begins by scanning a region of the primary volume, which is then compared with a corresponding region of the secondary volume. An identification of the scanned region is stored in a compare delta map when the comparison results in a discrepancy between the scanned region and the corresponding region. Data is copied from the primary volume to the secondary volume, using the compare delta map as a guide to locate the data to copy. If the data protection system has failed just prior to the restore process being initiated, it is termed a re-baseline, and the entire primary volume is scanned. If the data protection system is active prior to the restore process being initiated, it is termed a re-synchronization, and is optimized by scanning only select regions of the primary volume.
摘要翻译：在连续数据保护系统中同步辅助卷与主卷的方法通过扫描主卷的区域开始，然后将其与辅助卷的相应区域进行比较。当比较导致扫描区域和对应区域之间的差异时，扫描区域的识别被存储在比较增量图中。将数据从主卷复制到辅助卷，使用比较增量映射作为指导来定位要复制的数据。如果在恢复过程正在启动之前数据保护系统发生故障，则称为重新基准，并扫描整个主卷。如果数据保护系统在恢复过程启动之前处于活动状态，则称为重新同步，并且仅通过扫描主卷的选择区域进行优化。

摘要： A method for efficiently writing data to a redundant array of inexpensive disks (RAID) includes: writing an entire slice to the RAID at one time, wherein a slice is a portion of the data to be written to each disk in the RAID; and maintaining information in the RAID for slices that have been written to disk. A system for efficiently writing data to a RAID includes a buffer, a parity generating device, transfer means, and a metadata portion in the RAID. The buffer receives data from a host and accumulates data until a complete slice is accumulated. The parity generating device reads data from the buffer and generates parity based on the read data. The transfer means transfers data from the buffer and the generated parity to the disks of the RAID. The metadata portion is configured to store information for slices that have been written to disk.

摘要： A composite part consisting of a metallic matrix and reinforcing fibers is fabricated by the simultaneous winding of the fiber and plasma spraying of the matrix onto a rotating mandrel, wherein an axi-symmetric part is produced with multiple layers of the fibers aligned in the circumferential direction. Single or multiple fiber strands are wound onto a mandrel and simultaneously sprayed with the heated powder matrix material using a thermal spray process. Rotation and translation of the mandrel produces an axi-symmetric composite part. The content of the fiber material in the plasma sprayed matrix is typically up to 40% by volume. The light-weight composite part is produced in a single processing step. The part may be used either directly, or as an insert in other components with or without further densification.

摘要： A method for tracking changes on a primary volume in a continuous data protection system writes data to the primary volume. A copy of the data is written to a secondary volume, the secondary volume including all writes made to the primary volume. Each write made to the secondary volume is mapped in a data structure, such that the data structure tracks changes on the primary volume between two different points in time.
