摘要： A novel system and apparatus for transmitting data between the two nodes of a network is provided. The transmission is effected by using an error recovery protocol featuring a positive group acknowledgement. A sender unit on one node receives the user data and groups the data into consecutive cells, the cells being clustered into groups, each cell in a group being assigned a unique sequence number. The groups of cells are transmitted over a physical channel to a receiver unit on a different node. The receiver unit examines the cell stream and issues an acknowledgment message to the sender unit only when all of the cells in a group have been received. Once the sender unit has completed the transmission of a group of cells, it starts observing the physical channel for an acknowledgement message from the receiver unit. If after a predetermined time period the acknowledgement message has not been received, the sender unit transmits the group of cells again. This system allows to reduce the number of acknowledgement messages between the sender unit and the receiver unit while allowing low error-rate transmission between the nodes of the network.
摘要翻译：提供了一种用于在网络的两个节点之间传输数据的新型系统和装置。通过使用具有正组确认的错误恢复协议实现传输。一个节点上的发送者单元接收用户数据并将数据分组成连续的小区，小区被聚集成组，组中的每个小区被分配唯一的序列号。这些小区通过物理信道传输到不同节点上的接收机单元。只有当组中的所有单元已被接收时，接收器单元检查单元流并向发送器单元发出确认消息。一旦发送方单元完成了一组小区的传输，就开始从物理信道接收来自接收机单元的确认消息。如果在预定时间段之后还没有接收到确认消息，则发送器单元再发送一组单元。该系统允许减少发送器单元和接收器单元之间的确认消息的数量，同时允许网络节点之间的低错误率传输。

摘要： A method for identifying data for relocation in a multivolume file system. The method includes generating a file location map, the file location map containing a list of the locations of files that occupy space on each of a plurality of volumes of the file system, wherein The file system comprising least a first volume and a second volume. The method further includes updating the file location map in accordance with changes in a file change log for the file system, and identifying data residing on the first volume of the file system by scanning the file location map. Using the identified data, a ratio of per-file activity during a first time period relative to overall file system activity over a second time period is calculated to derive a file activity ratio for each of the files of the identified data. Files are then selected for relocation based on the file activity ratio.

摘要： A system and method for logging for asynchronously replicating volume groups. A write request to write data to a location in a volume may be received. Metadata associated with the write request may be stored. It may be determined if the write request possibly overlaps with one or more earlier write requests to the volume that have not yet been replicated to a secondary storage. The data may be stored in a replication log only if the write request possibly overlaps with one or more earlier write requests to the volume. The data may not be stored in the replication log if the write request does not overlap with one or more earlier write requests to the volume. The data may be written to the location in the volume. Changes to the volume may periodically be replicated to the secondary storage using the replication log.

摘要： System and method for tracking changes to a volume. A write request to write data to a first location in the volume may be received. It may be determined if the first location is overlapping with or adjacent to one or more locations of earlier write requests to the volume. First location information may be stored in a data structure in response to determining that the first location is overlapping with or adjacent to one or more second locations of earlier write requests to the volume. The first location information may identify the first location and the one or more second locations. Second location information may be removed from the data structure, where the second location information identifies the one or more second locations of earlier write requests to the volume. The data may be written to the first location in the volume in response to the write request.

摘要： Apparatus and methods for distributing iSCSI and SCSI targets. The initiator may assist in the distribution and order the SCSI commands. A subset of target storage processors may act as proxies. Target storage processors forward requests to a selected target storage processor which decides whether any and which of the other target storage processors is to process a forwarded request. The target storage processors may act as peers. A target storage processor communicates each received request to all of the other storage processors. Each of the target storage processors determines whether a request it received is to execute. A target storage processors may arrange themselves into layers to divide the SCSI and iSCSI protocol work. A distributed system associates each of multiple egress target storage processors with a respective ingress target storage processor and associates a set of blocks of storage with each of the egress target storage processors.

摘要： A new method of processing Asynchronous Transfer Mode (ATM) signaling messages is described wherein a plurality of computing units (CUs), each running signaling processing software, collectively provide signaling processing services for all the ports of a switch. As more ports, and more cards, are added to a switch, CUs can be incrementally added to support additional traffic. More significantly, in order to optimize the utilization rates of the plurality of CUs, the method provides for dynamic load-sharing of signaling traffic between CUs, such that a CU is allocated not on a per port basis, but on a per switched virtual circuit (SVC) session basis.

摘要： A computer-implemented method and apparatus manages block mapping. The block mapping maps physical blocks in a block storage device to virtual blocks of a virtual address space. The method involves assigning a generation number from a net of generation numbers to each block mapping entry, where the block mapping entry correlates a physical block with a virtual block. A maximum generation number of the set of generation numbers is increased and a first block mapping entry is marked dirty in response to an update of a correlated first virtual block. A generation number of the first block mapping entry is set to the maximum generation number. Finally, a generation number of a second block mapping entry having a lowest generation number is set to a generation number of the first block mapping entry.
