  • System and method for fault-tolerant remote direct memory access using single port host channel adapter hardware
    Patent number: 10868864
    Abstract: A fault-tolerant Remote Direct Memory Access (RDMA) system and method enables RDMA operations for a given queue pair to be initiated over first and second network fabrics associated with first and second physical R_Keys. The fault-tolerant RDMA system/method supports host channel adapter hardware having only one port while maintaining network fabric fault tolerance by virtualizing the R_Key associated with the first and second network fabrics.

  • Virtual switch
    Publication number: 20040139236
    Abstract: An electronic system comprises a processor, network interface controller (“NIC”) and a virtual switch. The virtual switch may comprise software executed by the processor and may include a plurality of virtual ports. The virtual ports may provide communications with an application running on the processor and the network interface controller.
