    Abstract: Computing apparatus includes a host processor, which runs a virtual machine monitor (VMM), which supports a plurality of virtual machines and includes a cryptographic security software module. A network interface controller (NIC) links the host processor to a network so as to transmit and receive data packets from and to the virtual machines and includes a cryptographic security hardware logic module, which when invoked by the VMM, applies the cryptographic security protocol to the data packets while maintaining a state context of the protocol with respect to each of the virtual machines. Upon encountering an exception in applying the cryptographic security protocol, the NIC transfers the data packet, together with the state context of the cryptographic security protocol with respect to the given virtual machine, to the cryptographic security software module for processing.

    Abstract: A method for data storage includes provisioning, in a cluster of computers, including at least first and second computers, which are connected to a packet data network, a range of RAM on the second computer for use by the first computer. Blocks of data are stored in the provisioned range for use by programs running on the first computer. Upon incurring a page fault on the first computer in response to a request for a page of virtual memory by a program running on the first computer, a block swap request is directed to the NIC of the first computer with respect to the requested page. In response to the block swap request, an RDMA read request is initiated by the NIC via the network to the NIC of the second computer, to retrieve the requested page from the provisioned range, so as to resolve the page fault.

    Abstract: A Network Interface Controller (NIC) includes a network interface, a peer interface and steering logic. The network interface is configured to receive incoming packets from a communication network. The peer interface is configured to communicate with a peer NIC not via the communication network. The steering logic is configured to classify the packets received over the network interface into first incoming packets that are destined to a local Central Processing Unit (CPU) served by the NIC, and second incoming packets that are destined to a remote CPU served by the peer NIC, to forward the first incoming packets to the local CPU, and to forward the second incoming packets to the peer NIC over the peer interface not via the communication network.

    Abstract translation: 网络接口控制器（NIC）包括网络接口，对等接口和转向逻辑。 网络接口被配置为从通信网络接收传入的分组。 对等体接口被配置为不通过通信网络与对等网络进行通信。 转向逻辑被配置为将通过网络接口接收的分组分类为目的地由NIC服务的本地中央处理单元（CPU）的第一入局分组，以及指向由对等体服务的远程CPU的第二传入分组 NIC，将首次传入的数据包转发到本地CPU，并通过对等接口将第二个传入数据包转发到对等网络，而不是通过通信网络。

    Abstract: A method for data transfer includes receiving in an operating system of a host computer an instruction initiated by a user application running on the host processor identifying a page of virtual memory of the host computer that is to be used in receiving data in a message that is to be transmitted over a network to the host computer but has not yet been received by the host computer. In response to the instruction, the page is loaded into the memory, and upon receiving the message, the data are written to the loaded page.

    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.
