QNAP Dual-Port 100GbE PCIe 4.0 Network Expansion Card

The QNAP QXG-100G2SF-CX6 is a dual-port network expansion card designed to deliver ultra-high-speed connectivity for demanding data environments. It features the advanced Mellanox ConnectX-6 Dx controller, which enables a total throughput of up to 200 Gbps by supporting multiple Ethernet speeds such as 1, 10, 25, 40, and 50 Gbps. This flexibility makes it suitable for a wide range of network setups, from standard to high-performance configurations.

Equipped with two QSFP28 ports, the card allows for versatile connection options and supports Port Trunking. This means you can combine the two ports to maximize data transfer efficiency, which is especially useful in environments where large volumes of data need to move quickly and reliably. The card also supports SR-IOV, providing dedicated bandwidth for virtual machines, and RoCE technology to reduce latency, making it a strong choice for virtualization and latency-sensitive applications.

Compatibility is broad, covering QNAP’s QTS and QuTS hero operating systems as well as Windows and Linux platforms. This makes the QXG-100G2SF-CX6 a practical upgrade for professionals working with all-flash storage systems, VMware virtualization, or any setup that demands fast, reliable network performance. The inclusion of both low-profile and full-height brackets ensures it fits a variety of server and workstation cases.
