    Abstract: A network node includes a bus switching element, and a network adapter, an accelerator and a host, all coupled to communicate via the bus switching element. The network adapter is configured to communicate with remote nodes over a communication network. The host is configured to establish a RDMA link between the accelerator and the RDMA endpoint by creating a Queue Pair (QP) to be used by the accelerator for communication with the RDMA endpoint via the RDMA link. The accelerator is configured to exchange data, via the network adapter, between a memory of the accelerator and a memory of the RDMA endpoint.

    Abstract: A network adapter includes one or more network ports, multiple bus interfaces, and a processor. The one or more network ports are configured to communicate with a communication network. The multiple bus interfaces are configured to communicate with multiple respective Central Processing Units (CPUs) that belong to a multi-CPU device. The processor is configured to support an Option-ROM functionality, in which the network adapter holds Option-ROM program instructions that are loadable and executable by the multi-CPU device during a boot process, and, in response to a request from the multi-CPU device to report the support of the Option-ROM functionality, to report the support of the Option-ROM functionality over only a single bus interface, selected from among the multiple bus interfaces connecting the network adapter to the multi-CPU device.

    Abstract: A method for management of a host computer that includes a management controller configured to carry out, independently of the host CPU, host management instructions contained in management packets compliant with a first data link protocol. The method includes receiving the management packets from a first network operating in accordance with the first data link protocol. The management packets are encapsulated in data packets compliant with a second data link protocol, different from the first data link protocol. The data packets are transmitted to a second network, operating in accordance with the second data link protocol. The transmitted data packets are received from the second network in a network interface controller (NIC), which is installed in the host computer and connected to the second network. The NIC decapsulates the management packets from the received data packets and passes the decapsulated management packets via a sideband connection to the management controller.

    Abstract: A method for memory access includes maintaining in a host memory, under control of a host operating system running on a central processing unit (CPU), respective address translation tables for multiple processes executed by the CPU. Upon receiving, in a peripheral device, a work item that is associated with a given process, having a respective address translation table in the host memory, and specifies a virtual memory address, the peripheral device translates the virtual memory address into a physical memory address by accessing the respective address translation table of the given process in the host memory. The work item is executed in the peripheral device by accessing data at the physical memory address in the host memory.

    Abstract: A method for data transfer includes receiving in a data transfer operation data to be written by a peripheral device to a specified virtual address in a random access memory (RAM) of a host computer. Upon receiving the data, it is detected that a page that contains the specified virtual address is marked as not present in a page table of the host computer. The peripheral device receives a notification that the page is not present and an estimate of a length of time that will be required to make the page available and selects a mode for handling of the data transfer operation depending upon the estimate.

    Abstract: A method for data transfer includes receiving in an input/output (I/O) operation a first segment of data to be written to a specified virtual address in a host memory. Upon receiving the first segment of the data, it is detected that a first page that contains the specified virtual address is swapped out of the host memory. At least one second page of the host memory is identified, to which a second segment of the data is expected to be written. Responsively to detecting that the first page is swapped out and to identifying the at least one second page, at least the first and second pages are swapped into the host memory. After swapping at least the first and second pages into the host memory, the data are written to the first and second pages.
