Qnap QXG-10G2SF-NXE 10Gbps 2 x SFP+ PCI-Express network card

Dual 10Gbps SFP+ connectivity

The Qnap QXG-10G2SF-NXE is a PCI-Express network card delivering two 10Gbps SFP+ ports for high-throughput server and workstation links. It targets IT teams building low-latency storage fabrics or virtualisation clusters that need more bandwidth than standard gigabit adapters provide. Wake-on-LAN support allows remote power management across the network.

Upgrade from single-port or gigabit NICs

This card replaces older single-port 10GbE adapters or dual-port gigabit cards when aggregate throughput must rise above 1Gbps per link. The jump is worth it when backup windows shrink, VM migration stalls on saturated links, or iSCSI storage traffic exceeds the capacity of existing copper interfaces. Two ports also enable link aggregation or segregated traffic paths without adding a second card.

Fits a free PCIe slot and SFP+ transceivers

Installation requires an available PCI-Express slot and compatible SFP+ modules or direct-attach cables matched to your switch optics. The low-profile bracket suits dense rackmount chassis where full-height cards cannot fit. By moving 10GbE traffic off onboard ports, the adapter frees integrated interfaces for management or lower-priority workloads.
