    Abstract: A method in a system that includes first and second devices that communicate with one another over a fabric that operates in accordance with a fabric address space, and in which the second device accesses a local memory via a local connection and not over the fabric, includes sending from the first device to a translation agent (TA) a translation request that specifies an untranslated address in an address space according to which the first device operates, for directly accessing the local memory of the second device. A translation response that specifies a respective translated address in the fabric address space, which the first device is to use instead of the untranslated address is received by the first device. The local memory of the second device is directly accessed by the first device over the fabric by converting the untranslated address to the translated address.

    Abstract: A method includes communicating between at least first and second devices over a bus in accordance with a bus address space, including providing direct access over the bus to a local address space of the first device by mapping at least some of the addresses of the local address space to the bus address space. In response to indicating, by the first device or the second device, that the second device requires to access a local address in the local address space that is not currently mapped to the bus address space, the local address is mapped to the bus address space, and the local address is accessed directly, by the second device, using the mapping.

    Abstract: A method for data storage includes configuring a driver program on a host computer to receive commands in accordance with a protocol defined for accessing local storage devices connected to a peripheral component interface bus of the host computer. When the driver program receives, from an application program running on the host computer a storage access command in accordance with the protocol, specifying a storage transaction, a remote direct memory access (RDMA) operation is performed by a network interface controller (NIC) connected to the host computer so as to execute the storage transaction via a network on a remote storage device.

    Abstract translation: 一种用于数据存储的方法包括：在主计算机上配置驱动程序，以根据为访问连接到主计算机的外围组件接口总线的本地存储设备而定义的协议接收命令。 当驱动程序从主计算机上运行的应用程序接收到根据协议的存储访问命令指定存储事务时，由连接的网络接口控制器（NIC）执行远程直接存储器访问（RDMA）操作 到主计算机，以便经由远程存储设备上的网络执行存储交易。

    Abstract: A network adapter includes a port and one or more circuits. The port communicates packets over a network in which switches forward packets in accordance with tuples of the packets. The one or more circuits are to hold a user-programmable scheme specifying assignments of the packets of a given flow destined to a peer node to sub-flows having respective different tuples, assign first packets of the given flow to one or more of the sub-flows in accordance with the user-programmable scheme, by setting respective tuples of the first packets, transmit the first packets to the peer node via the port, monitor notifications received from the network, the notifications being indicative of respective states of the sub-flows, based on the notifications and on the user-programmable scheme determine an assignment of second packets of the given flow to the sub-flows, and transmit the second packets to the peer node via the port.
