摘要： In a network having a computing system interfacing with a storage system via a switch, an average transmit wait count value is compared with a first threshold value. The average transmit wait count value is updated when a switch port has a frame available for transmission but is unable to transmit the frame if a port of the storage system is unable to receive the frame or if another switch port is unable to receive the frame. A congestion message is generated for notifying a management module of congestion at the switch port when the average transmit wait count value reaches the first threshold value. Depending upon the characteristics of the congestion, a notification is sent to the computing system to either only reduce a rate of write operations to reduce congestion, or to reduce both the rate of write operations and a rate of read operations.

摘要： A management request complying with a first protocol is generated by a management application executed by a computing system coupled to a network element. A processor executable agent encapsulates a management request using a second protocol. The encapsulated management request is transmitted using a third protocol via a link used by the computing system to send input/output requests for reading and writing data to a storage device. The management request is de-encapsulated to provide the management request complying with the first protocol to a management module of the network element. The management module of the network element prepares a response to the management request complying with the first protocol. A processor executable service at the network element encapsulates the response using the second protocol. The encapsulated response is transmitted to the computing system using the third protocol. The response complying with the first protocol is extracted from the encapsulated response. The response complying with the first protocol is provided to the management application.

摘要： Method and system for a first network device and a second network device is provided. The first network device and the second network device communicate with each other via a first network link and a second network link. A traffic type between the first network device and the second network device is excluded from link aggregation. When a packet is received from the first network device; and if the packet is excluded from link aggregation, then the first network link or the second link is selected to transmit the packet based on a physical port identifier identifying a port of the first network device.

摘要： A method and a Fibre Channel switch element are provided that allows communication between a host system and a target device attached to a proprietary switch fabric in a network. The Fibre Channel switch element includes a first port that communicates with the target device through the proprietary switch fabric by logging on behalf of the host system so that the proprietary switch behaves as if it was directly communicating with the host system; and a second port that communicates with the host system and collects host bus adapter (“HBA”) identification information, wherein the HBA identification information is used to map the first port to the second port so that when the host system communicates with the target device the Fibre Channel switch element is transparent to the proprietary switch fabric.

摘要： A network device is provided. The network device includes a processor having access to a memory storage device storing instructions for execution by the processor; and a first flexible port having a physical layer that can be configured to operate as a first link type or a second link type based on a control signal sent by the processor. The first flexible port receives a packet from the computing system. The first flexible port determines an egress flexible port for transmitting the packet to its destination. A routing module generates a route control tag for the packet that includes an identifier identifying the egress flexible port, a location identifier identifying where the packet is stored at the first flexible port and a translation identifier identifying an action that is to be performed on the packet at the egress port before sending the packet to the destination.
