The QXG-25G2SF-BCM 25 GbE network expansion card, supports PCIe 4.0 and provides up to 50Gbps total throughput to overcome performance bottlenecks. Supporting offload functionality including RDMA and SR-IOV, the QXG-25G2SF-BCM greatly boosts network efficiency and is ideal for I/O-intensive and latency-sensitive virtualization and data centers. The QXG-25G2SF-BCM is a perfect match for all-flash storage to realize the highest performance potential for ever-demanding IT challenges.
NAS and PC
The QXG-25G2SF-BCM can be installed in a QNAP NAS or Windows® PC.
PCIe 4.0
PCIe Gen 4 x8 provides up to 50 Gbps transfer speeds.
SR-IOV
Improves the network performance of virtual machines.
RDMA (RoCE)
Reduces latency, lowers CPU utilization, and boosts overall throughput
Compatible with NAS and PC
The QXG-25G2SF-BCM network expansion card supports QNAP NAS, Windows®, and Linux® devices, allowing you to maximize the performance potential of all your networked devices.
- NAS operating system: QTS 5.2.4 (and later), QuTS hero h5.2.4 (and later). Check compatibility list
- Windows®: Windows® 11 24H2, Windows Server® 2022 / 2025 (driver required)
- Linux®: Ubuntu® 20.04 LTS (driver required)
Gain up to 50 Gbps connectivity
By virtually bundling two 25 GbE ports with SMB multichannel or port trunking, you gain larger bandwidth for your QNAP NAS. Let's see which features are suitable for your usage scenarios:
- SMB Multichannel: Multiply the available bandwidth (50Gbps) between NAS and directly-connected clients. Suited for personal use.
- Port trunking: Increases file access efficiency for simultaneous data access with multiple members. Recommended for users who deploy network switches in their IT infrastructure.
Strengthen your virtualization environment with SR-IOV
The QXG-25G2SF-BCM supports SR-IOV, which can allocate bandwidth resources from a physical network card directly to VMs on the NAS. It helps improve network efficiency, ensuring reliable VM applications and reduced CPU overheads.
Supports RoCE for Reduced Latency and Enhanced Performance for VM Environments
The QXG-25G2SF-BCM supports RoCE, which can access a network directly in RAM to effectively reduce latency and enhance performance and efficiency for VMware® virtualization environments.
Build a 25 GbE network environment
Increase your IT performance and productivity by using the QXG-25G2SF-BCM with QNAP's switch, making it easier than ever to deploy a blazing-fast 100GbE network for your business.
