LREC9712HF-2SFP is a PCIe x4 1Gbps Dual-Port SFP Sever Fiber Ethernet Adapter based on Intel I350 chipset, compatible with PCIe x8 and x16 slot. The adapter is mainly used on a server workstation and its performance has been optimized while being designed, which makes system I/O no longer be the bottleneck on the application of high-end network. The adapter can be grouped up together through its two or four ports to expand network bandwidth and ensure network performance. It can also real-time detect automatically and combine the communication route from the faulty port with others to achieve high-performance communications incessantly.
