Abstract
An information handling system includes a processor operable to instantiate a virtual machine on the information handling system, a converged network adapter (CNA) operable to provide a virtual function to the virtual machine, and a trapped virtual function module separate from the CAN. The trapped virtual function is operable to receive data from the virtual machine, add a transport layer header and a network layer header to the data to provide a remote direct memory access (RDMA) packet, and send the RDMA packet to the CNA. The CNA is further operable to add an Ethernet header to the RDMA packet to provide an Ethernet packet, and send the Ethernet packet to a peer information handling system.
