摘要： A plurality of types of volumes are maintained, a volume being a logical arrangement of storage space on one or more data storage devices. A volume type field is used to designate the type of a particular volume, and a flexible volume paradigm is selected by the volume type field for interpreting data within a data structure written to a data storage device of the one or more data storage devices. A physical volume block number to virtual volume block number mapping pair (pvbn/vvbn pair) is designated by the volume type field, the pvbn/vvbn pair is used to translate a physical volume block number to a virtual volume block number. A request to write a data to a first block of the particular volume is received, a pvbn/vvbn pair is determined. The data is written to the physical block designated by the pvbn/vvbn pair.

摘要： The invention provides a method and system for duplicating all or part of a file system while maintaining consistent copies of the file system. The file server maintains a set of snapshots, each indicating a set of storage blocks making up a consistent copy of the file system as it was at a known time. Each snapshot can be used for a purpose other than maintaining the coherency of the file system, such as duplicating or transferring a backup copy of the file system to a destination storage medium. In a preferred embodiment, the snapshots can be manipulated to identify sets of storage blocks in the file system for incremental backup or copying, or to provide a file system backup that is both complete and relatively inexpensive. Also in a preferred embodiment, shadow snapshots can be maintained, with a shadow snapshot including a set of member storage blocks that formed a consistent file system other than an active file system, with a set of selected member storage blocks removed from the consistent file system.

摘要： The invention provides techniques for duplicating all or part of a file system while maintaining consistent copies of the file system. A preferred embodiment reads data from the source file system (mapped according to a first storage block arrangement) creates an image stream and writes this data onto the destination file system (in accordance with a second storage block arrangement). Thus, the invention allows an image transfer between file systems that have dissimilar characteristics. An intermediate storage medium can be used to store or transmit the data read from the source file system before writing the data to the destination file system. (For example, the intermediate storage medium can include a magnetic tape or other archival device, or a network.) Another aspect of the invention writes the data to the intermediate storage medium using a normalized or implied block list. The information is read from the intermediate storage medium using normalized or implied block list and written to the destination file system according to the second storage block arrangement. Another aspect of the invention is that the invention determines a first set of block numbers (BNs), determines where the blocks referenced by these BNs are to be stored, and updates the BNs accordingly.

摘要： A is a method is disclosed for integrating a file system with a RAID array that exports precise information about the arrangement of data blocks in the RAID subsystem. The file system examines this information and uses it to optimize the location of blocks as they are written to the RAID system. Thus, the system uses explicit knowledge of the underlying RAID disk layout to schedule disk allocation. The method uses separate current-write location (CWL) pointers for each disk in the disk array where the pointers simply advance through the disks as writes occur. The algorithm used has two primary goals. The first goal is to keep the CWL pointers as close together as possible, thereby improving RAID efficiency by writing to multiple blocks in the stripe simultaneously. The second goal is to allocate adjacent blocks in a file on the same disk, thereby improving read back performance. The method satisfies the first goal by always writing on the disk with the lowest CWL pointer. For the second goal, a new disks chosen only when the algorithm starts allocating space for a new file, or when it has allocated N blocks on the same disk for a single file. A sufficient number of blocks is defined as all the buffers in a chunk of N sequential buffers in a file. The result is that CWL pointers are never more than N blocks apart on different disks, and large files have N consecutive blocks on the same disk.
摘要翻译： A公开了一种用于将文件系统与导出关于RAID子系统中的数据块的布置的精确信息的RAID阵列集成的方法。文件系统检查此信息，并使用它来优化块写入RAID系统时的位置。因此，系统使用底层RAID磁盘布局的显式知识来计划磁盘分配。该方法为磁盘阵列中的每个磁盘使用单独的当前写入位置（CWL）指针，其中当发生写入时，指针简单地通过磁盘。所使用的算法有两个主要目标。第一个目标是使CWL指针尽可能靠近，从而通过同时写入条带中的多个块来提高RAID效率。第二个目标是将文件中的相邻块分配到同一个磁盘上，从而提高回读性能。该方法通过始终使用最低CWL指针在磁盘上写入来满足第一个目标。对于第二个目标，只有当算法开始为新文件分配空间时，或者在同一个磁盘上为单个文件分配了N个块时才选择新的磁盘。足够数量的块被定义为文件中N个顺序缓冲区块中的所有缓冲区。结果是CWL指针在不同的磁盘上绝对不超过N个块，大文件在同一个磁盘上有N个连续的块。

摘要： A data storage system is coupled to a host computer system for the transfer of data between the host and a plurality of data storage devices. The data storage devices are coupled to a plurality of data transfer channels with each data storage channel be coupled to at least a respective one of the data storage devices. Each data transfer channel includes a data buffer and an autonomously operating controller for transferring between the channels data buffer and data storage device. A non-volatile random access storage memory is provided to store cached pages of data. An interface couples the data storage system to the host and through which data is transferred. A reconfigurable data path permits selective data transfer couplings between the data transfers channels, the non-volatile memory, and the interface. A controller directs the configuration of the data path and controls a direct memory access controller for burst transferring data between the interface and the channel data buffers, between the interface and the non-volatile memory and between the non-volatile memory and the channel data buffers.
