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.

摘要： 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.

摘要： 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.

摘要： A method for communication includes establishing a full-duplex communication link between first and second nodes. The link includes multiple first lanes for conveying first communication traffic in a first link direction and multiple second lanes for conveying second communication traffic in a second link direction. Signals are exchanged between the first and second nodes to indicate a requested change in lane activity in the first link direction. Responsively to the signals, a number of the first lanes that are active is changed so that the first node conveys the first communication traffic to the second node over a first number of the first lanes, while the second node conveys the second communication traffic to the first node over a second number of the second lanes, which is different from the first number.

摘要： A method of communication includes receiving, in a network interface device, first and second requests from an initiator process running on an initiator host to transmit, respectively, first and second data to first and second target processes running on one or more target nodes, via a packet network. A single dynamically-connected initiator context is allocated for serving both the first and second requests. A first connect packet referencing the dynamically-connected (DC) initiator context is directed to the first target process so as to open a first dynamic connection with the first target process, followed by transmission of the first data over the first dynamic connection. The first dynamic connection is closed after the transmission of the first data, and a second connect packet is transmitted so as to open a second dynamic connection with the second target process, followed by transmission of the second data.

摘要： A network communication device includes a host interface, which is coupled to communicate with a host processor, having a memory, so as to receive a work request to convey one or more data blocks over a network. The work request specifies a memory region of a given data size, and at least one data integrity field (DIF), having a given field size, is associated with the data blocks. Network interface circuitry is configured to execute an input/output (I/O) data transfer operation responsively to the work request so as to transfer to or from the memory a quantity of data that differs from the data size of the memory region by a multiple of the field size, while adding the at least one DIF to the transferred data or removing the at least one DIF from the transferred data.

摘要： A method for operating a peripheral device includes receiving at the peripheral device service orders, which are identified with respective service instances and are submitted to the peripheral device over the bus by software applications running on a host processor, which write copies of the service orders to a memory. The received service orders are queued for execution by the peripheral device. When one or more of the service orders have been dropped from the queue prior to execution, a recovery of a selected service instance is initiated by submitting a read request from the peripheral device to the memory over the bus to receive a copy of any unexecuted service order associated with the service instance.
