The LREC9804BF-4SFP+ is a high-performance server network adapter independently developed by Shenzhen Lianrui Electronics Co., Ltd. (LR-LINK). Powered by the Intel XL710 quad-port Ethernet controller, it delivers four 10GbE SFP+ interfaces over a single PCI Express v3.0 x8 slot. Engineered for next-generation data centers, this adapter offers advanced virtualization, load balancing, and redundancy features — making it the ideal networking solution for critical server deployments and high-performance computing environments.
Overview

The LREC9804BF-4SFP+ 10GbE server adapter integrates four independent 10G SFP+ ports on a single PCI Express v3.0 x8 slot, providing flexible connectivity for 10000Base-SR, 10000Base-LR, and 10000Base-Cu transceivers to suit diverse network deployment scenarios. Built on the Intel XL710 quad-port Ethernet MAC+PHY controller, the adapter features stateless offloading capabilities that intelligently distribute network traffic across CPU cores, significantly improving throughput in multiprocessor systems.

With support for LSO/GSO software offloading, the adapter effectively reduces host CPU overhead, freeing up valuable computing resources for business-critical applications. Through IEEE 802.3AD link aggregation, multiple ports can be bonded into logical groups to expand bandwidth and provide link redundancy. When a port fails, the system automatically detects the fault and reroutes traffic to other healthy ports within the same group, ensuring uninterrupted communication.

Combined with Microsoft RSS or Linux Extensible I/O, the adapter efficiently balances network loads across multiple CPU cores, maximizing the performance of multi-core server platforms.
