Lr-link LREC9902BF-2QSFP+ PCI Express dual QSFP+ port 40G optical Fiber Ethernet server adapter is a high performance and high bandwidth server adapter (optical fiber network card) independently developed by Shenzhen Lianrui Electronics Co., LTD. It is another latest work of the company's RESEARCH and development team. Mainly used for servers and high-end devices. The LREC9902BF-2QSFP+ provides simple integration into any PCI Express X8. The 40Gigabit network performance has been optimized so that the system's input/output is not a bottleneck in high-performance network applications.
The LR-Link LREC9902BF-2QSFP+ is based on the Intel XL710AM2 High performance Ethernet controller. In addition to the functionality of managing MAC and PHY Ethernet layers, the controller manages PCI Express packet traffic at its switched LINK and physical/logical layers. Using hardware acceleration, the controller unloads tasks from the host, such as TCP/UDP/IP checksum calculation and TCP split.
Lr-link LREC9902BF-2QSFP+ is an ideal solution for realizing multiple network segments, mission-critical high performance and high performance servers in network application environments.
