摘要： Some embodiments of the present invention provide blade servers having blade switches that function as switches in the data plane, but do not have a Domain_ID. Control plane switching functions are performed by a fabric switch (e.g., a core switch) to which the blade server is attached. A fabric switch to which a blade switch is attached may perform address assignment functions for blades of the blade server. The blade switch preferably converts FLOGI requests to FDISC requests that are forwarded to an attached fabric switch. Some implementations provide for the multiple fabric switches, all of which are configured for communication with at least one blade switch, to establish and maintain the state of a virtual Domain_ID.

摘要： A Data Center Ethernet ("DCE") network and related methods and device are provided. A DCE network simplifies the connectivity of data centers and provides a high bandwidth, low latency network for carrying Ethernet, storage and other traffic. A Fibre Channel ("FC") frame, including FC addressing information, is encapsulated in an Ethernet frame for transmission on a Data Center Ethernet ("DCE") network. The Ethernet address fields may indicate that the frame includes an FC frame, e.g., by the use of a predetermined Organization Unique Identifier ("OUI") code in the D_MAC field, but also include Ethernet addressing information. Accordingly, the encapsulated frames can be forwarded properly by switches in the DCE network whether or not these switches are configured for operation according to the FC protocol. Accordingly, only a subset of Ethernet switches in the DCE network needs to be FC-enabled. Only switches so configured will require an FC Domain_ID.
摘要翻译：提供数据中心以太网（“DCE”）网络及相关方法和设备。 DCE网络简化了数据中心的连接性，并提供了高带宽，低延迟的网络，用于承载以太网，存储和其他流量。包含FC寻址信息的光纤通道（“FC”）帧封装在以太网帧中，用于在数据中心以太网（“DCE”）网络上传输。以太网地址字段可以指示该帧包括FC帧，例如通过使用D_MAC字段中的预定机构唯一标识符（“OUI”）代码，但也包括以太网寻址信息。因此，无论这些交换机是否配置为根据FC协议进行操作，都可以通过DCE网络中的交换机正确转发封装的帧。因此，只有DCE网络中的以太网交换机的子集才需要启用FC。只有这样配置的交换机将需要FC Domain_ID。

摘要： Techniques are provided for performing discovery in a Fibre Channel over Ethernet (FCoE) network. An FCoE Node (ENode) discovers the FCoE Forwarders (FCFs) connected to its network segment by transmitting a solicitation message to the multicast MAC address "All-FCF-MACs". All FCFs receive packets with this multicast MAC address including the solicitation message that announces the presence of the ENode. Each FCF replies with a unicast advertisement message that provides the ENode with a MAC address of the responding FCF. The ENode builds a list of the FCFs available on its network segment and may then establish a virtual link with one or more of the FCFs through a Fabric Login (FLOGI) exchange.

摘要： A system (e.g., Fibre Channel Error Detecting Code (FC-EDC)) that maps the "standard" Hamming codes onto the bits of a 33-bit control block is provided. The system employs a "rotation" of the check positions in a two-dimensional parity-check matrix for the FC-EDC. The specification discloses a computer-implemented program to test further modifications and permutations of the "standard" distance-4 parity-check matrix to yield an FC-EDC with enhanced error-detecting properties, designed to detect the most likely errors in the known physical environment. By using a parity-check matrix with the "rotation" property, certain error-detecting properties of the parity-check matrix are ensured, and the computation time for searching for a matrix with enhanced error-detecting properties becomes much shorter.

摘要： A fast, lightweight, reliable, packet-based protocol (ABC) that operates independent of the type of networking protocol used by the underlying physical layer of the network is disclosed. More specifically, the packet based protocol operates independently of or is capable of encapsulating over physical layer protocols such as but not limited to MAC, Ethernet, Ethernet II, HARD or IP. The protocol defines at least three different types of frames including Information frames, Supervisory frames, and Unnumbered frames. In various embodiments of the invention, the Information, Supervisory, and Unnumbered frames include DSAP and SSAP field with semantics which are sufficiently large to support the various physical layer protocols that may be used on the network. The Information frames, Supervisory frames, and Unnumbered frames also have the ability to support urgent data delivery and certain memory management functions. The protocol is further capable of support the multiplexing of layers higher than the protocol so that multiple higher layer applications may share the same connection. Finally, the protocol of the present invention supports both flow control and congestion control, to help reduce the incidence of lost or dropped packets at a receiving node or over the network respectively.
摘要翻译：公开了一种快速，轻量级，可靠的基于分组的协议（ABC），其独立于由网络的底层物理层使用的网络协议的类型进行操作。更具体地说，基于分组的协议独立于或能够通过物理层协议进行封装，例如但不限于MAC，以太网，以太网II，硬接口或IP。该协议定义了至少三种不同类型的帧，包括信息帧，监督帧和无编号帧。在本发明的各种实施例中，信息，监督和未编号的帧包括具有足够大以支持可能在网络上使用的各种物理层协议的语义的DSAP和SSAP字段。信息框架，监督框架和无编号框架还能够支持紧急数据传送和某些内存管理功能。该协议还能够支持高于协议的层的复用，使得多个较高层应用可以共享相同的连接。最后，本发明的协议支持流量控制和拥塞控制，以帮助减少接收节点或网络上丢失或丢弃的分组的发生。

摘要： An apparatus and method for preventing the disruption of Fibre Channel Fabrics caused by ReConfigure Fabric (RCF) messages is disclosed. The apparatus includes a storage area network and a plurality of Fibre Channel Switches arranged in a Fabric. Each of the plurality of Switches includes logic to selectively configure their Ports to either reject or accept RCF messages. When configured to reject RCF messages, the Switch Port that receives an RCF message will generate a reject message along with a reason code explanation "E Port Isolated", and then transition into an Isolated state. When the Switch that generated the RCF message receives the reject message, its Port also transition into the Isolated state. In accordance with the method of the present invention, either a Storage Service Provider or a client can access the Switches of the Fabric through either a command line interpreter or a management application. Once access to the Fabric is established, the logic of the Ports of the Switches can be selectively configured to reject or accept RCF messages as described above.
摘要翻译：公开了一种用于防止由ReConfigure Fabric（RCF）消息引起的光纤通道结构中断的装置和方法。该装置包括存储区域网络和布置在织物中的多个光纤通道交换机。多个开关中的每一个包括用于选择性地配置其端口以拒绝或接受RCF消息的逻辑。当配置为拒绝RCF消息时，接收RCF消息的交换机端口将生成拒绝消息以及原因代码说明“E端口隔离”，然后转换到隔离状态。当生成RCF消息的交换机接收到拒绝消息时，其端口也转换到隔离状态。根据本发明的方法，存储服务提供商或客户端可以通过命令行解释器或管理应用程序访问结构的交换机。一旦建立了对Fabric的访问，交换机端口的逻辑可以有选择地配置为拒绝或接受RCF消息，如上所述。
