    • A system for conveying information includes a signal transport device. The signal transport device includes a set of links operable to convey a first set of information signals from a first computer module to a second computer module and a link operable to convey a transaction request credit signal associated with the first set of information signals, the signal indicating whether at least a portion of a transaction request message may be sent using the first set of information signals. The device also includes a set of links operable to convey a second set of information signals in the opposite direction of the first set of information signals and a link operable to convey a transaction request credit signal associated with the second set of information signals, the signal indicating whether at least a portion of a transaction request message may be sent using the second set of information signals.
    • 用于传送信息的系统包括信号传送装置。 信号传输设备包括一组可操作以将第一组信息信号从第一计算机模块传送到第二计算机模块的链接,以及可操作以传达与第一组信息信号相关联的交易请求信用信号的链接,该信号 指示是否可以使用第一组信息信号发送交易请求消息的至少一部分。 该设备还包括一组链接,可操作以在第一组信息信号的相反方向上传送第二组信息信号,以及可操作以传达与第二组信息信号相关联的交易请求信用信号的链接,该信号 指示是否可以使用第二组信息信号发送交易请求消息的至少一部分。

    • A sampling based technique for eliminating duplicate data (de-duplication) stored on storage resources, is provided. According to the invention, when a new data set, e.g., a backup data stream, is received by a server, e.g., a storage system or virtual tape library (VTL) system implementing the invention, one or more anchors are identified within the new data set. The anchors are identified using a novel anchor detection circuitry in accordance with an illustrative embodiment of the present invention. Upon receipt of the new data set by, for example, a network adapter of a VTL system, the data set is transferred using direct memory access (DMA) operations to a memory associated with an anchor detection hardware card that is operatively interconnected with the storage system. The anchor detection hardware card may be implemented as, for example, a FPGA is to quickly identify anchors within the data set. As the anchor detection process is performed using a hardware assist, the load on a main processor of the system is reduced, thereby enabling line speed de-duplication.
    • 提供了用于消除存储在存储资源上的重复数据(重复数据删除)的基于抽样的技术。 根据本发明,当服务器(例如,实施本发明的存储系统或虚拟磁带库(VTL))系统接收到诸如备份数据流的新数据集时,在新的数据集内识别出一个或多个锚点 数据集。 根据本发明的说明性实施例,使用新颖的锚定检测电路来识别锚。 在通过例如VTL系统的网络适配器接收到新数据集时,使用直接存储器访问(DMA)操作将数据集传送到与锚定检测硬件卡相关联的存储器,该存储器与存储器可操作地互连 系统。 锚定检测硬件卡可以被实现为例如FPGA快速识别数据集内的锚点。 由于使用硬件辅助进行锚定检测处理,系统的主处理器上的负载减少,从而实现线速度重复数据删除。

    • The techniques introduced here include storage systems including a storage controller configured to access data and a storage subsystem including a storage device having n ports, where n is an integer greater than one, and where the storage device is configured to store the data and to make the data available to the storage controller via each of the n ports. The storage systems also include a communication fabric configured to couple the storage controller to each of the n ports of the storage device via m paths, where m is an integer greater than n, so that the storage system is configured to tolerate failure in up to m−1 paths through the communication fabric, such that the data in the storage device remains accessible to the storage controller even in the presence of failure in up to m−1 paths of the m paths.
