The LREC9714HF-4SFP is a PCI Express x4 four-port Gigabit SFP Ethernet server adapter developed by LR-LINK based on the Intel I350 master solution; the adapter is designed for servers and high-end devices. And the performance is optimized, so that system I / O is no longer the bottleneck of high-end network applications. The adapter can be bundled into groups for fault tolerance, automatically detecting and routing communications from the failed port to other members of the same group to continue operation for uninterrupted communication. The adapter has integrated hardware acceleration and is capable of performing TCP/UDP/IP checksum offloading and TCP segmentation tasks. Host processing technology can offload the accelerator and free up CPU resources to free up more CPU resources to handle other applications. The adapter is the ideal solution for deploying multiple networks and deploying critical network applications and environments on high-performance servers.
