Product information

Description

The QNAP QXG-25G2SF-E810 is a dual-port internal fiber network card with the Intel® Ethernet Controller E810-XXVAM2. It supports PCIe Gen4 (backwards compatible with Gen3) and offers up to 25Gbps per port (10/25Gbps supported). Designed for I/O-intensive and latency-sensitive environments, the card accelerates file sharing, multimedia transmission and real-time video editing by combining high throughput with Network Offload features and support for SMB Multichannel aggregation.

Advantages

The QXG-25G2SF-E810 provides high-speed 25GbE connectivity with PCIe Gen4 compatibility, low-latency operation through network offloading, and compatibility with NAS (QTS and QuTS hero), Windows and Linux systems. It supports Forward Error Correction (FEC) to improve reliability over long or noisy links and enables SMB Multichannel to aggregate links for higher effective bandwidth.

Suitable for

  • Data centers and enterprise storage servers
  • High-bandwidth NAS systems and workstations
  • Virtualization hosts, containers and cloud compute nodes
  • Multimedia production, 4K/8K video editing and real-time streaming

Key specifications

  • Model: QXG-25G2SF-E810
  • Controller: Intel® Ethernet Controller E810-XXVAM2
  • Interface: PCI Express (Gen4, backward compatible with Gen3)
  • Ports: Dual 25GbE fiber ports (10/25Gbps supported)
  • Max transfer rate: 25000 Mbit/s per port
  • Supported standards: IEEE 802.1p, 802.3x, 802.3az, 802.3ae, 802.3ad, 802.1as, 802.1Q, IEEE 1588
  • Features: Network Offload, SMB Multichannel, Forward Error Correction (FEC)
  • Compatibility: QNAP NAS (QTS, QuTS hero), Windows 11, Windows Server, Linux (e.g., Ubuntu 20.04 LTS)

How to use

Install the QXG-25G2SF-E810 into an available PCIe slot (PCIe Gen4 recommended; Gen3 compatible) on a supported NAS, server or workstation. Connect fiber cables to the card's SFP+ ports and ensure the switch or connected device supports 25GbE. On QNAP NAS systems enable the card via the operating system (QTS or QuTS hero) and configure SMB Multichannel or bonding on client and server sides as needed. Install appropriate drivers on Windows or Linux hosts following vendor instructions.

Usage recommendations

Use certified 25GbE network switches and compatible fiber cables to achieve reliable 25Gbps links. Enable FEC when operating over long or noisy links, and use SMB Multichannel or link aggregation to combine multiple 25GbE connections for higher aggregate bandwidth. Verify driver compatibility and firmware updates for optimal performance.
