摘要： A method, in a host adapter circuit configured for coupling a host electronic device with one of a fiber channel loop and a point-to-point communication channel, for receiving data at the host adapter circuit from one of the fiber channel loop and the point-to-point communication channel. The method includes providing a selectable control signal configured for indicating whether the host adapter circuit is coupled to the fiber channel loop or the point-to-point communication channel. The method further includes providing a front-end receive circuit. The front-end receive circuit is configured for coupling with an input data port. The input data port represents one of the fiber channel loop and the point-to-point communication channel. The method also includes coupling the front-end receive circuit with the selectable control signal. Additionally, the method includes coupling an output of the front-end receive circuit with a decoder of the host adapter circuit, wherein the front-end receive circuit is configured to process, responsive to the selectable control signal, either fiber channel loop data from the fiber channel loop or point-to-point data from the point-to-point communication channel from the input data port to provide parallel data having a predefined size to the decoder circuit.

摘要： A method for automatically arbitrating for mastership of a fiber channel loop in a host adapter circuit configured for coupling a host electronic device with the fiber channel loop. The host adapter circuit has a processor and a loop control circuit different from the processor. The loop control circuit is coupled to a memory of the host adapter circuit. The method includes sending out a host ARBITRATE primitive on the fiber channel loop. The method further includes employing the loop control circuit to monitor received ARBITRATE primitives received at the host adapter circuit from the fiber channel loop. There is also included ascertaining, using the loop control circuit, whether one of the received ARBITRATE primitives represents the host ARBITRATE primitive sent out previously. If the one of the received ARBITRATE primitives represents the host ARBITRATE primitive sent out previously, the method includes placing a target device coupled to the fiber channel loop in an OPENED state for receiving data from the host electronic device.

摘要： A method that utilizes virtual channels and a common pool of credits, controlled by a transmitter to maximize the throughput across an Inter-Switch Link in a Fibre Channel network. Each virtual channel is allocated a minimum number of credits and the remaining credits of the ISL are held in a common pool.

摘要： The present invention provides a system and a method for filtering a plurality of frames sent between devices coupled to a fabric by Fiber Channel connections. Frames are reviewed against a set of individual frame filters. Each frame filter is associated with an action, and actions selected by filter matches are prioritized. Groups of devices are “zoned” together and frame filtering ensures that restrictions placed upon communications between devices within the same zone are enforced. Zone group filtering is also used to prevent devices not within the same zone from communicating. Zoning may also be used to create LUN-level zones, protocol zones, and access control zones. In addition, individual frame filters may be created that reference selected portions of frame header or frame payload fields.

摘要： Virtual channels are used to improve quality of service through a large port count switch. Data frames are sent from one small switch to another small switch within the large port count switch on virtual channels. The use of virtual channels helps prevent congestion caused by a first external source device sending data to a first external destination device from affecting a second external source device sending data to a second external destination device.

摘要： In a communication network system having a multi-switch Fiber Channel fabric, adjacent switches are communicatively coupled together by a plurality of links. The links are selectively determined to join a trunked group for enabling frames received at one switch to be routed over the links in the trunked group to the adjacent switch in an evenly distributed manner. In one embodiment, a link within the trunked group is coupled to a pair of ports residing on adjacent switches each having a designated trunking master port. The traffic load at one switch is routed through the trunking master port which distributes the load across multiple links and guarantees that the load is received at the adjacent switch with “in-order” delivery.

摘要： A modular Fibre Channel switch includes a data switching path and a message switching path to provide logical point to point connections between switch ports. The data switching path includes a bank of shared SRAM memory devices that are accessed in a time-sliced protocol by each switch port. A receiving switch port writes a data frame to the bank of shared SRAM and the transmitting switch port then reads the data frame from the shared SRAM thereby effecting the logical point to point connection. Because the switch port includes a frame logic circuit that allows for an arbitrary start of frame address, each frame can be written to the first available DRAM device thus eliminating the need to buffer the data frame while waiting for a predetermined DRAM device to cycle in the time sliced protocol. The message switching path includes a message crossbar switch that is barrel shifted in a time sliced fashion to effect message passing among the switch ports. The switch includes a motherboard containing an embedded G_Port ASIC, a message crossbar switch to handle message passing and shared memory that is used to perform data switching. The switch also includes a central processing unit daughter board and external switch port daughter boards.
摘要翻译：模块化光纤通道交换机包括数据交换路径和消息交换路径，以提供交换机端口之间的逻辑点对点连接。数据交换路径包括一组由每个交换机端口以时间分片协议访问的共享SRAM存储器件。接收开关端口将数据帧写入共享SRAM的存储体，然后发送开关端口从共享SRAM中读取数据帧，从而实现逻辑点对点连接。因为开关端口包括允许帧地址的任意开始的帧逻辑电路，所以每帧可被写入第一可用DRAM器件，从而消除了在等待预定的DRAM器件周期性地缓冲数据帧的需要时间片协议。消息交换路径包括以时间分片方式桶式移位的消息交叉开关，以实现交换机端口之间的消息传递。该交换机包括一个包含嵌入式G_Port ASIC的主板，用于处理消息传递的消息交叉开关和用于执行数据交换的共享存储器。该开关还包括中央处理单元子板和外部开关端口子板。

摘要： A link level flow control technique implements a “pull frame” transmission model in a Fibre Channel network. In one embodiment, frames remain in a first Fibre Channel device until they are requested by a second Fibre Channel device, wherein the second Fibre Channel device does not issue a request unless conditions are such that it can immediately transmit the frame toward its target destination. In another embodiment, a Fibre Channel device provides hardware messaging capability to support the pull model. In yet another embodiment, multiple Fibre Channel devices in accordance with the invention may be coupled to provide high port-count Fibre Channel switches.
