LREC9902BF-2QSFP+ is a PCI Express x8 dual port 40G Ethernet server adapter independently developed by Shenzhen Lianrui Electronics Co., Ltd. based on the Intel XL710 main control. It is the latest development of the research and development team of Shenzhen Lianrui Electronics Co., Ltd. The server adapter is mainly used in IDC rooms, high-end servers, high-end devices. The LREC9902BF-2QSFP+ provides a simple integration into any PCI Express x8 Ethernet server network. The adapter is designed for 40 Gigabit network performance. Optimization makes the input/output of network systems no longer a bottleneck for high-performance network applications.
The LREC9902BF-2QSFP+ is based on the Intel XL710 high-performance Ethernet controller. In addition to managing the MAC and PHY Ethernet layer functions, the controller manages PCI Express data table traffic at its switch link and physical/logical layer. Using hardware acceleration, the controller offloads tasks from the host, such as TCP/UDP/IP checksum calculations and TCP partitioning.
The LREC9902BF-2QSFP+ is based on the high-speed PCI Express v3.0 x8 interface and is backward compatible with PCI Express v2.1, PCI Express v2.0 transfer rate interfaces.
