LRES3040PF-OCP is a dual-port fiber optic 25G Ethernet network adapter with OCP 3.0 SFF structure developed by Shenzhen Lianrui Electronics Co., Ltd. based on the mellanox ConnectX-4 master control solution. It has 1/10/25G rate connection to meet the virtualization application of network facilities and local hardware support based on Ethernet stateless offload engine, direct connection technology, etc.

The SR-IOV technology of LRES3040PF-OCP provides dedicated adapter resources for virtual machines in the server to meet the network isolation and protection functions. At the same time, I/O virtualization provides better server utilization for data centers while reducing costs, wiring complexity and other excellent characteristics, and allows more virtual machines to run on the same hardware to meet more user needs.

The NVGRE, VXLAN and GENEVE hardware offload engines used in the LRES3040PF-OCP can effectively solve the high CPU utilization problem encountered when the virtual machine traffic is transmitted through logical tunnels in encapsulation formats such as NVGRE and VXLAN. These offload engines encapsulate and decapsulate the overlay protocol headers, enabling traditional offloads to be performed on encapsulated traffic in these and other tunnel protocols (geneva, MPLS, QinQ, etc.).
