Powered by an NVIDIA Mellanox ConnectX-6 Lx SmartNIC controller, the QXG-25G2SF-CX6 Dual-Port 25GbE PCIe 4.0 x8 Network Expansion Card from QNAP uses PCIe 4.0 x8 connectivity and provides dual 25GbE ports with SFP28 connectors. Using Port Trunking to combine multiple ports, speeds of up to 50GbE can be achieved for accelerating file sharting and intensive data transfers. With SR-IOV support, the QXG-25G2SF-CX6 boosts network efficiency and is made for I/O-intensive and latency-sensitive virtualization applications and data centers. It is backward compatible with PCIe 3.0 and 2.0, as well as 10GbE.
