QNAP QXG-100G2SF-E810 Dual-Port 100GbE PCIe 4.0 x16 Network Expansion Card

The QNAP QXG-100G2SF-E810 is a network expansion card with two 100-gigabit ports that installs in a standard PCIe 4.0 x16 slot. It gives servers and workstations a direct path to 100Gbps throughput, making it a practical choice for administrators who need to move large datasets quickly, feed multiple virtual machines with steady bandwidth, or eliminate bottlenecks in an all-flash storage environment.

Built around the Intel Ethernet Controller E810, the card maintains low latency even when links are saturated. Forward Error Correction adds a layer of reliability for links that span longer distances inside a data center or between racks, so critical transfers finish without retransmissions.

The low-profile bracket fits densely packed server chassis, while QSFP28 connectors simplify cabling to existing 100GbE switches. Windows and Linux drivers are available, which means the card can slide into almost any modern server, hyper-converged node, or high-performance workstation. When paired with QNAP all-flash storage, the card removes network congestion and lets you fully realize the speed of NVMe arrays.

Whether you run a virtualization host that demands consistent IO, a high-performance computing cluster that exchanges large datasets, or a backup server that must finish replication jobs inside a tight window, the QXG-100G2SF-E810 provides the bandwidth headroom and reliability you need today with room to grow tomorrow.
