摘要： A Fiber Channel router used to join fabrics. EX_ports are used to connect to the fabrics. The EX_port joins the fabric but the router will not merge into the fabric. Ports in the Fiber Channel router can be in a fabric, but other ports can be connected to other fabrics. Fiber Channel routers can be interconnected using a backbone fabric. Global, interfabric and encapsulation headers are developed to allow routing by conventional Fiber Channel switch devices in the backbone fabric and simplify Fiber Channel router routing. Phantom domains and devices must be developed for each of the fabrics being interconnected. Front phantom domains are present at each port directly connected to a fabric. Each of these is then connected to at least one translate phantom domain. Zoning is accomplished by use of a special LSAN zoning naming convention. This allows each administrator to independently define devices are accessible.

摘要： Placing virtualization agents in the switches which comprise the SAN fabric. Higher level virtualization management functions are provided in an external management server. Conventional HBAs can be utilized in the hosts and storage units. In a first embodiment, a series of HBAs are provided in the switch unit. The HBAs connect to bridge chips and memory controllers to place the frame information in dedicated memory. Routine translation of known destinations is done by the HBA, based on a virtualization table provided by a virtualization CPU. If a frame is not in the table, it is provided to the dedicated RAM. Analysis and manipulation of the frame headers is then done by the CPU, with a new entry being made in the HBA table and the modified frames then redirected by the HBA into the fabric. This can be done in either a standalone switch environment or in combination with other switching components located in a director level switch. In an alternative embodiment, specialized hardware scans incoming frames and detects the virtualized frames which need to be redirected. The redirection is then handled by translation of the frame header information by hardware table-based logic and the translated frames are then returned to the fabric. Handling of frames not in the table and setup of hardware tables is done by an onboard CPU.
摘要翻译：将虚拟化代理放在构成SAN结构的交换机中。外部管理服务器提供了更高层次的虚拟化管理功能。传统的HBA可以在主机和存储单元中使用。在第一实施例中，在开关单元中提供一系列HBA。 HBA连接到桥芯片和存储器控制器，以将帧信息放置在专用存储器中。基于由虚拟化CPU提供的虚拟化表，HBA完成已知目的地的常规转换。如果一个帧不在表中，它被提供给专用的RAM。然后由CPU完成对帧头的分析和处理，在HBA表中创建一个新条目，然后修改的帧由HBA重定向到该结构中。这可以在独立的开关环境中或与位于导向器电平开关中的其他开关元件组合完成。在替代实施例中，专用硬件扫描传入帧并检测需要被重定向的虚拟化帧。然后通过基于硬件表的逻辑的帧头信息的翻译来处理重定向，然后将翻译的帧返回到结构。处理不在表中的帧和硬件表的设置由板载CPU完成。

摘要： A Layer 2 network switch is partitionable into a plurality of switch fabrics. The single-chassis switch is partitionable into a plurality of logical switches, each associated with one of the virtual fabrics. The logical switches behave as complete and self-contained switches. A logical switch fabric can span multiple single-chassis switch chassis. Logical switches are connected by inter-switch links that can be either dedicated single-chassis links or logical links. An extended inter-switch link can be used to transport traffic for one or more logical inter-switch links. Physical ports of the chassis are assigned to logical switches and are managed by the logical switch. Legacy switches that are not partitionable into logical switches can serve as transit switches between two logical switches.

摘要： The entire FCoE fabric is a single virtual domain, even though there may be multiple FCFs and FDFs. The virtual domain is a different Domain_ID than any of the FCFs. In certain embodiments there are multiple FCFs, of which one is selected as the master or designated FCF. The master FCF performs normal fabric configuration in conjunction with the Fibre Channel fabric. The master FCF assigns the virtual domain FC node IDs and controls development of subdomain IDs. Virtual links are instantiated between the master FCF and other FCFs, between top level FDFs and the FCFs and between the FDFs at each of various levels. FDFs connected to ENodes proxy the master FCF for most FIP operations. FIP FLOGI and FDISC operations are handled by the master FDF, but the FDFs convert the FIP FLOGI requests to VD_FLOGI requests, which include information about the FDF handling the transaction.
摘要翻译：整个FCoE架构是单个虚拟域，尽管可能有多个FCF和FDF。虚拟域是与任何FCF不同的Domain_ID。在某些实施例中，存在多个FCF，其中一个被选择为主或指定的FCF。主FCF与光纤通道结构一起执行正常的光纤配置。主FCF分配虚拟域FC节点ID并控制子域ID的开发。虚拟链路在主FCF和其他FCF之间，在顶级FDF和FCF之间以及在各种级别的FDF之间实例化。连接到ENodes的FDF为大多数FIP操作代理主FCF。 FIP FLOGI和FDISC操作由主FDF处理，但FDF将FIP FLOGI请求转换为VD_FLOGI请求，其中包括有关处理事务的FDF的信息。
