摘要： The present invention provides methods and devices for implementing a Low Latency Ethernet (“LLE”) solution, also referred to herein as a Data Center Ethernet (“DCE”) solution, which simplifies the connectivity of data centers and provides a high bandwidth, low latency network for carrying Ethernet and storage traffic. Some aspects of the invention involve transforming FC frames into a format suitable for transport on an Ethernet. Some preferred implementations of the invention implement multiple virtual lanes (“VLs”) in a single physical connection of a data center or similar network. Some VLs are “drop” VLs, with Ethernet-like behavior, and others are “no-drop” lanes with FC-like behavior. Some preferred implementations of the invention provide guaranteed bandwidth based on credits and VL. Active buffer management allows for both high reliability and low latency while using small frame buffers. Preferably, the rules for active buffer management are different for drop and no drop VLs.

摘要： Redundancy of data and/or Inline Power in a wired data telecommunications network from a first network device and a second network device configured as power sourcing equipment (PSE) devices and coupled together and to a third network device (such as a PD) via a Y device is provided by providing redundant signaling to/from each of the pair of network devices, and coupling a port of each of the network devices to the Y device and from there to a third port where a third network device such as a PD may be coupled. Because the Y device is essentially passive, communications paths between the PSE devices and the PD are provided for negotiating master/slave status and other status and related information among the respective network devices. Dynamic impedance matching is provided to handle situations where not all devices are plugged in and as a communications technique among the devices.
摘要翻译：有线数据电信网络中的数据和/或在线电力从第一网络设备和被配置为电源设备（PSE）设备的第二网络设备连接在一起并通过经由网络设备（例如PD）耦合到第三网络设备 Y设备通过向/从每对网络设备提供冗余信令来提供，并且将每个网络设备的端口耦合到Y设备，并从那里连接到第三端口，其中诸如PD的第三网络设备耦合。因为Y设备本质上是被动的，所以提供PSE设备和PD之间的通信路径用于在各个网络设备之间协商主/从状态和其他状态和相关信息。提供动态阻抗匹配以处理不是所有设备插入的情况，以及设备之间的通信技术。

摘要： Redundancy of data and/or Inline Power in a wired data telecommunications network from a pair of power sourcing equipment (PSE) devices via an automatic selection device is provided by providing redundant signaling to/from each of the pair of PSE devices, and coupling a port of one PSE device and a redundant port of the second PSE device to respective first and second interfaces of a port of the selection device. The selection device initially selects one of the two PSE devices and communicates data and/or Inline Power to a third interface of the selection device. A powered device (PD) coupled to that third interface communicates data and/or Inline Power with the selected one of the first and second PSE device through the selection device. Upon detection of a condition, such as a failure condition, the selection device may select the other of the two interfaces.

摘要： This document discusses, among other things, an example system and methods for memory expansion. An example embodiment includes detecting a memory command directed to a logical rand and a number of physical ranks mapped to the logical rank. The example embodiment may also include issuing the memory command to the number of physical ranks based on determining that the memory command is to be issued to the number of physical ranks.
摘要翻译：本文档还讨论了一个用于内存扩展的示例系统和方法。示例实施例包括检测针对映射到逻辑秩的逻辑rand和多个物理等级的存储器命令。该示例性实施例还可以包括基于确定存储器命令将被发布到物理等级的数量而将存储器命令发布到物理队列的数量。

摘要： Redundancy of data and/or inline power in a wired data telecommunications network from a pair of network devices via a selection device is provided by communicating redundant signals with each of the pair of network devices and coupling ports of the first network device and corresponding ports of the second network device to paired inputs of the selection device. The selection device operates: 1) under the control of the pair of network devices, one acting as master and one as slave, the master selecting (for each port or for all ports) one of the two paired inputs and causing the selection device to communicate data and/or inline power via a third port of the selection device to a third network device receiving data connectivity and/or inline power from the selection device; or 2) to route two redundant signals to a third network device which then selects one for use.
