The LR-Link LREC9902BF-2QSFP+ is a high-performance network interface card designed to significantly boost data throughput in demanding server environments. Powered by the Intel XL710 controller, this adapter features two QSFP+ ports that each deliver a transfer rate of 40 Gbps, making it suitable for high-bandwidth applications. It connects via a PCI Express 3.0 x8 interface, though it remains fully compatible with PCIe x16 slots for flexible installation in various hardware setups. To ensure efficiency in virtualized environments, the card supports SR-IOV, VXLAN, NVGRE, and Geneve, while hardware offloads for TCP/UDP/IP checksums and TCP partitioning reduce the processing load on your CPU. It is compatible with 40000Base-SR, 40000Base-LR, and 40000Base-Cu standards, allowing you to choose between different cabling options based on your distance requirements. The hardware is designed for stability, operating within a temperature range of 0 °C to 55 °C with a modest power consumption of 5.6W. Weighing 120 g and measuring 17 x 3 x 22 cm, the adapter is built for professional integration. To accommodate different chassis sizes, the package includes both a standard full-height bracket and a low-profile bracket, ensuring you can fit the card into either a full-sized tower or a slim server blade.
