摘要： An apparatus is provided, for performing a direct memory access (DMA) operation between a host memory in a first server and a network adapter. The apparatus includes a host frame parser and a protocol engine. The host frame parser is configured to receive data corresponding to the DMA operation from a host interface, and is configured to insert markers on-the-fly into the data at a prescribed interval and to provide marked data for transmission to a second server over a network fabric. The protocol engine is coupled to the host frame parser. The protocol engine is configured to direct the host frame parser to insert the markers, and is configured to specify a first marker value and an offset value, whereby the host frame parser is enabled to locate and insert a first marker into the data.

摘要： Methods, apparatus and systems for reducing usage of Doorbell Rings in connection with RDMA operations. A portion of system memory is employed as a Memory-Mapped Input/Output (MMIO) address space configured to be accessed via a hardware networking device. A Send Queue (SQ) is stored in MMIO and is used to facilitate processing of Work Requests (WRs) that are written to SQ entries by software and read from the SQ via the hardware networking device. The software and logic in the hardware networking device employ pointers identifying locations in the SQ corresponding to a next write WR entry slot and last read WR entry slot that are implemented to enable WRs to be written to and read from the SQ during ongoing operations under which the SQ is not emptied such that doorbell rings to notify the hardware networking device that new WRs have been written to the SQ are not required.

摘要： A flexible arrangement allows a single arrangement of Ethernet channel adapter (ECA) hardware functions to appear as needed to conform to various operating system deployment models. A PCI interface presents a logical model of virtual devices appropriate to the relevant operating system. Mapping parameters and values are associated with the packet streams to allow the packet streams to be properly processed according to the presented logical model and needed operations. Mapping occurs at both the host side and at the network side to allow the multiple operations of the ECA to be performed while still allowing proper delivery at each interface.

摘要： The real-time test controller maintains a failure database containing a history of past failures for devices under test and selectively sorts the history for the device to be tested. The diagnostic testing sequence is then rearranged with tests having higher failure rates being conducted first. If faults are detected, a message is provided to the operator and the failure database is either manually or automatically updated with the latest fault information. In this manner, a continuously updated history of faults is maintained and the most efficient testing sequence is followed, resulting in significant time and cost savings.

摘要： Methods, apparatus and software for implementing enhanced data center congestion management for non-TCP traffic. Non-congested transmit latencies are determined for transmission of packets or Ethernet frames along paths between source and destination end-end-nodes when congestion along the paths is not present or minimal. Transmit latencies are similarly measured along the same source-destination paths during ongoing operations during which traffic congestion may vary. Based on whether a difference between the transmit latency for a packet or frame and the non-congested transmit latency for the path exceeds a threshold, the path is marked as congested or not congested. A rate at which the non-TCP packets are transmitted along the path is then managed as function of a rate at which the path is marked as congested. In one implementation, non-TCP traffic is managed by mimicking a Data Center TCP technique, under which the congestion marking status of the path is substituted as an input to a DCTP algorithm in place of the normally-used ECN-Echo flag input. The congestion window output by the DCTCP algorithm is then used to manage the rate at which non-TCP packets to be forwarded via the path are transmitted from a source end-node.
摘要翻译：用于实现非TCP流量增强数据中心拥塞管理的方法，设备和软件。确定沿着路径的拥塞不存在或最小时，沿着源端和目的端端节点之间的路径传输分组或以太网帧的非拥塞发送延迟。在正在进行的操作期间，沿着相同的源 - 目的地路径类似地测量发射延迟，在此期间，业务拥塞可能变化。基于分组或帧的发送等待时间与路径的非拥塞发送等待时间之间的差是否超过阈值，路径被标记为拥塞或不拥塞。然后，以路径被标记为拥塞的速率的函数来管理沿着路径发送非TCP分组的速率。在一个实现中，通过模拟数据中心TCP技术来管理非TCP流量，在该技术下，将路径的拥塞标记状态替换为DCTP算法的输入来代替常用的ECN-Echo标志输入。然后使用DCTCP算法输出的拥塞窗口来管理从源端节点传送经由路径转发的非TCP分组的速率。
