Product information

Description

The QNAP QXG-25G2SF-CX6 is an internal fiber network card featuring an NVIDIA Mellanox ConnectX-6 Lx SmartNIC controller and a PCIe Gen4 host interface (backwards compatible with Gen3/Gen2). It delivers up to 25 Gbps transfer speeds and supports Port Trunking to combine ports for higher aggregated bandwidth. With SR-IOV support, this card is designed to improve network efficiency in I/O-intensive and latency-sensitive virtualization and data center environments.

Advantages

The QXG-25G2SF-CX6 provides high-speed 25GbE connectivity while maintaining compatibility with existing PCIe generations. Port Trunking enables up to 50GbE aggregated throughput for accelerated file sharing and heavy data transfers. SR-IOV and the Mellanox ConnectX-6 Lx SmartNIC controller enhance virtualization performance and reduce CPU overhead, and the fiber interface supports stable, long-reach wired connections suitable for data center deployments.

Suitable for

  • Data centers and server farms requiring high-bandwidth internal networking
  • Virtualization hosts and I/O-intensive virtual machines using SR-IOV
  • Workstations and servers running Windows 10, Windows Server, or Linux (driver required)
  • Environments needing aggregated bandwidth via Port Trunking (up to 50GbE)

Key specifications

  • Manufacturer: QNAP
  • Model: QXG-25G2SF-CX6
  • Controller: NVIDIA Mellanox ConnectX-6 Lx SmartNIC
  • Interface: PCIe Gen4 (backwards compatible with Gen3/Gen2)
  • Network interface: Fiber
  • Maximum data transfer rate: 25 Gbps
  • Port aggregation: Port Trunking (supports aggregated throughput up to 50GbE)
  • Virtualization support: SR-IOV
  • Compatibility: Windows 10, Windows Server, Linux (driver required), QNAP devices

How to use

Install the QXG-25G2SF-CX6 into a compatible PCIe slot on your server or workstation, ensuring the system is powered off before insertion. Secure the card and connect fiber cabling to the card’s SFP28 ports. Install the required drivers for your operating system (Windows or Linux) and configure network settings in the host OS or hypervisor. To increase bandwidth, configure Port Trunking/Link Aggregation on both the host and the network switch. For virtualization, enable and configure SR-IOV in the host platform and guest configurations where supported.

Usage recommendations

Use certified SFP28 fiber modules and compatible switches to ensure full 25GbE performance. Verify driver compatibility and firmware updates from QNAP or NVIDIA/Mellanox before deployment. When aggregating links, configure matching settings on the switch and confirm cabling and transceiver compatibility to achieve stable 50GbE throughput.
