1. The mini PCIe Gigabit server network card is a single compact, low-power server component that can provide fully integrated Gigabit Ethernet media access control and physical layer ports. 2. It uses high-performance for 82583 chip, and adopts PCIe architecture, and provides single-port network service in a relatively small area. Therefore, it can be used for servers and any other personal computers. 3. Dual-channel (x1) PCIe with a throughput of up to 2.5Gbps; compatible with mini PCIe card electromechanical specification revision 1.2 4. Only compatible with full-size mini PCIe card type and size; Compliant with PCIe basic specification revision 1.1 5.
