PCIe x8 Dual-port 25G SFP28 Ethernet Network Adapter (Mellanox Chip Based)



Key Features

  • It is a PCIe X8 dual port fiber 25G Ethernet network adapter.
  • It has a 1, 10, 25 GIGABit connection to meet the virtualization application of network facilities.
  • It provides better server utilization for the data center while reducing costs, cabling complexity, and so on.
  • It can effectively solve the problem that vm traffic is transmitted through encapsulated logical tunnels (such as NVGRE and VXLAN). It solves the network scalability and load problem on the host CPU.


LRES1026PF-2SFP28 is a PCIe x8 dual-port 25G ethernet network adapter developed by Shenzhen Lengrui Electronics Co., LTD based on mellanox chip. It has 1/10/25G connection for virtualization applications of network facilities, local hardware support based on Ethernet stateless uninstallation engine, direct connection technology, etc.

The SR-IOV technology of LRES1026PF-2SFP28 provides dedicated adapter resources for virtual machines in the server to meet the guarantee of isolation and protection. At the same time, I/O virtualization provides better server utilization in the data center while reducing costs and cabling complexity. Allow more virtual machines to run on the same hardware to meet more user needs.

LRES1026PF-2SFP28 adopts NVGRE, VXLAN and GENEVE hardware uninstallation engine to effectively solve the problem of virtual machine traffic transmission through encapsulation format (such as NVGRE and VXLAN) logical tunnel. It solves the network scalability and the load on the host CPU. These offloading engines encapsulate and unencapsulate coverage protocol headers, enabling traditional offloading to be performed on encapsulated traffic from these and other tunneling protocols (Geneva, MPLS, QinQ, etc.).

LRES1026PF-2SFP28 provides a very economical and flexible Ethernet adapter solution for Web 2.0, cloud, data analytics, database and storage platforms
