A method for data storage includes mapping a queue pair (QP) of a channel adapter to a specified Fiber Channel (FC) exchange for communication with a storage device. Upon receiving at the channel adapter from a host computer a storage command directed to the storage device, the storage command is executed by transmitting data packets over a switched network from the channel adapter to the storage device using the specified exchange and performing a remote direct memory access (RDMA) operation on the channel adapter using the mapped QP.

A communication apparatus includes a plurality of switch ports, each switch port including one or more port buffers for buffering data that traverses the switch port. A switch fabric is coupled to transfer the data between the switch ports. A switch control unit is configured to reassign at least one port buffer of a given switch port to buffer a part of the data that does not enter or exit the apparatus via the given switch port, and to cause the switch fabric to forward the part of the data to a destination switch port via the at least one reassigned port buffer.

A method for communication includes routing a first packet, which belongs to a given packet flow, over a first routing path through a communication network. A second packet, which follows the first packet in the given packet flow, is routed using a time-bounded Adaptive Routing (AR) mode, by evaluating a time gap between the first and second packets, routing the second packet over the first routing path if the time gap does not exceed a predefined threshold, and, if the time gap exceeds the predefined threshold, selecting a second routing path through the communication network that is potentially different from the first routing path, and routing the second packet over the second routing path.

A system and method of digital communication wherein a host on an InfiniBand network transmits Fibre Channel packets encapsulated within InfiniBand packets to a gateway which forwards the Fibre Channel packets to Fibre Channel device via a Fibre Channel network, and wherein Fibre Channel packets addressed to a host on an InfiniBand network are transmitted by a Fibre Channel device to a gateway, the gateway encapsulating the Fibre Channel packets within InfiniBand packets and transmitting the InfiniBand packets to an InfiniBand host, where the Fibre Channel packet is extracted.

A method and system for digital communication wherein nodes exchange messages at a first data rate in order to coordinate testing at a second, higher data rate. After testing is completed, the nodes exchange test results at the first data rate, and if conditions are satisfactory for operation at the second data rate user data are transmitted at the second data rate. Otherwise, user data are transmitted at the first data rate.

A method for communication includes sending a pause frame from a first node to a second node over a communication link between the nodes. In response to the pause frame, one or more data frames are immediately transmitted from the second node to the first node upon receipt of the pause frame at the second node.

摘要:
A method and switch system for optimizing the use of a given bandwidth in different communication network connections. The method comprises providing port bandwidth resources at a port of the network, and dynamically and automatically allocating said port bandwidth resources. In a preferred embodiment, the bandwidth resources include a cluster of 3 ports with a given bandwidth of 12x, which can be declared as a 12x port and two 4x ports or as a trio of three 4x ports. The declaration causes dynamic and automatic configuration of the three ports, thereby optimizing the use of the given bandwidth.
