LREC9712HT is a PCIe x4 dual-port Gigabit ethernet network adapter developed by Linkreal CO.,LTD. based on Intel I350 chip program, compatible with PCIe x8 and x16 channels. The adapter is designed for servers and server clusters and other network applications. It can realize fault tolerance and redundancy by bundling multiple ports into a group to expand network bandwidth and guarantee network performance, and it can automatically detect and realize real-time routing of communications from the faulty ports to other members of the same group for uninterrupted high-performance communications.
The LREC9712HT features integrated hardware acceleration to perform TCP/UDP/IP checksum offloading and TCP segmentation tasks. The host processing technology can offload the gas pedal. The host processing technology can offload the gas pedal, freeing up the CPU resource footprint to free up more CPU resources for other applications.
The LREC9712HT adopts a compact interface structure to better utilize server space, and allows two network ports to work simultaneously in full-duplex operation mode for high-performance network communication in a Gigabit Ethernet connection.
