    Abstract: A network interface apparatus includes a host interface for connection to a host processor and a network interface, which includes multiple distinct physical ports. Processing circuitry associates each of a plurality of virtual entities running on the host processor with a respective one of the physical ports, so that while both of the first and second physical ports are operational, the processing circuitry transmits data packets on behalf of first and second virtual entities, using assigned upper-layer addresses, through associated first and second physical ports. In response to an indication that the first physical port has ceased to operate, the processing circuitry transmits the data packets on behalf of the first virtual entity through the second physical port without changing the upper-layer addresses.

    Abstract: Computerized methods and systems are disclosed for configuring a network controller (NC). These methods and systems recognize, via a network device, e.g., hardware, software, processors, storage media, memory, a predetermined command from a management controller (MC). The network device responds to the predetermined command by configuring the NC with a message type associated with an event, and controlling enablement of a message associated with the message type using a selectable enable bit as defined in the predetermined command.

    Abstract: A method in a network node that includes a network adapter, a Baseboard Management Controller (BMC) and a host, includes connecting to a switch in a communication network using first and second ports of the network adapter, as member ports of a Link Aggregation Group (LAG). Management and data packets are simultaneously exchanged over the communication network via the LAG member ports, so that the management packets are exchanged between the BMC and a control server, and the data packets between the host and a remote node.

    Abstract: A peripheral device includes a host interface and processing circuitry. The host interface is to communicate with one or more hosts over a peripheral bus.
    The processing circuitry is to expose on the peripheral bus a peripheral-bus device that communicates with the one or more hosts using one or more instances of at least one bus storage protocol, to receive, using the exposed peripheral-bus device, Input/Output (I/O) transactions that are issued by the one or more hosts, and to complete the I/O transactions for the one or more hosts in accordance with one or more instances of at least one network storage protocol, by running at least part of a host-side protocol stack of the at least one network storage protocol.

    Abstract: Lock access is managed in a data network having an initiator node and a remote target by issuing a lock command from a first process to the remote target via an initiator network interface controller to establish a lock on a memory location, and prior to receiving a reply to the lock command communicating a data access request to the memory location from the initiator network interface controller. Prior to receiving a reply to the data access request, an unlock command issues from the initiator network interface controller. The target network interface controller determines the lock content, and when permitted by the lock accesses the memory location. After accessing the memory location the target network interface controller executes the unlock command. When the lock prevents data access, the lock operation is retried a configurable number of times until data access is allowed or a threshold is exceeded.
