QNAP QXG-25G2SF-CX6 Dual-Port 25GbE PCIe 4.0 x8 Network Expansion Card

Designed to deliver high-throughput connectivity where it matters most, the QNAP QXG-25G2SF-CX6 Dual-Port 25GbE PCIe 4.0 x8 network expansion card brings enterprise-grade networking to NAS, servers, and security appliances. Powered by an NVIDIA Mellanox ConnectX-6 Lx SmartNIC, this QNAP SFP28 module provides two 25GbE SFP28 ports and supports PCIe 4.0 x8 host connectivity to accelerate file sharing, storage replication, and high-resolution surveillance feeds. SR-IOV and SmartNIC features optimize virtualization performance and lower CPU overhead, making this card ideal for VM-dense environments, monitoring platforms, and security operations. Port trunking enables aggregated 50GbE throughput for bursty transfers and large dataset movement, while backward compatibility with PCIe 3.0/2.0 and 10GbE protects your existing infrastructure during upgrades. The low-profile bracket and QNAP-specific hardware options streamline installation in NAS chassis and compact servers. Upgrade networking for storage, virtualization, and surveillance monitoring—add the QNAP QXG-25G2SF-CX6 to your infrastructure to reduce latency and maximize throughput.
