Accelerate your network with the dual-port QNAP QXG-25G2SF-E810 featuring the Intel Ethernet E810-XXVAM2 chipset. It offers two 25GbE SFP28 links, PCIe Gen4 (compatible with Gen3), support for SMB Multichannel up to 50 Gb/s, and network offload for lower CPU load. Ideal for virtualization, data centers, and real-time video editing.
Two 25GbE SFP28 ports for maximum throughput

Two 25GbE SFP28 ports for maximum throughput

Achieve extremely fast transfers for NAS, servers, and workstations. Supported speeds of 10/25 Gb/s enable flexible integration into modern and existing networks.

PCIe Gen4 and network offload for lower latency

PCIe Gen4 and network offload for lower latency

PCIe Gen4 interface (compatible with Gen3) and hardware offload features boost performance, reduce CPU load, and improve responsiveness in demanding applications and virtualization.

Reliability with FEC and active cooling

Reliability with FEC and active cooling

Forward Error Correction helps correct bit errors and prevents packet loss. A heatsink with fan ensures stable performance even under prolonged load.

The QNAP QXG-25G2SF-E810 elevates connectivity for your NAS and servers to an enterprise level. Two 25GbE SFP28 ports enable extremely fast data transfers, while SMB Multichannel support can combine multiple links up to 50 Gb/s for even higher throughput. Thanks to network offload, the card offloads part of network operations to hardware, reducing latency and increasing performance.

Broad compatibility with QTS / QuTS hero, Windows 11 / Windows Server, and Linux ensures easy deployment. Forward Error Correction (FEC) minimizes packet loss and ensures reliable transmission over longer distances. Active cooling with a heatsink and fan keeps temperatures under control during sustained workloads.

Ideal for high-demand environments: virtualization, 4K/8K media rendering and editing, data aggregation in data centers, high-speed backups, and future expandability thanks to QNAP’s scalable 25/50/100GbE ecosystem.

  • 25GbE performance – 2× SFP28, speeds 10/25 Gb/s
  • PCIe Gen4 – backward compatible with Gen3
  • SMB Multichannel – multiple-link aggregation up to 50 Gb/s
  • FEC – reliable transfers over “noisy” channels
  • Network offload – lower CPU load, higher efficiency
  • Active cooling – stable performance during long workloads
  • Broad compatibility – QNAP NAS, Windows, Linux
