LREC9714HT is a 2U 4-port server nic independently developed by shenzhen lianrui electronics co., ltd. based on Intel chip solution, which is compatible with PCIex8 and x16 channels. The server adapter card is mainly designed for servers and high-end equipment, and its performance is optimized and improved during the design, so that the SYSTEM I/O is no longer the bottleneck of high-end network applications. The adapter is capable of fault tolerance and redundancy to expand network bandwidth and ensure network performance by bundling four ports into a group at the same time. It can automatically detect and route communication from the faulty port to other members of the same group for continuous high-performance communication. The adapter has integrated hardware acceleration for TCP/UDP/IP checksum load partitioning and TCP fragmentation tasks. Host processing technology can be divided into accelerators, freeing up CPU resources to free up more CPU resources to process other applications. This Ethernet card is an ideal solution for deploying multiple networks and critical network applications and environments on high performance servers.
The LREC9714HT is developed on the Intel I350 four-port Ethernet MAC+PHY (Media Access Controller and Physical Interface Transceiver) controller, which allows four ports to work in full-duplex mode simultaneously for high-performance network communication at the highest point in gigabit Ethernet connections. Link aggregation can be used to expand the bandwidth and save the PCI Express channel resources without occupying the bus bandwidth. The LREC9714HT also supports THE PCI-SIG single-root I/O Virtualization and Sharing Specification (SR-IOV).
