NAS and PC
The QXG-100G2SF-BCM can be installed in a QNAP NAS or Windows® PC.
PCIe 4.0
PCIe Gen 4 x16 provides up to 256 Gbps transfer speeds.
SR-IOV
Improves the network performance of virtual machines.
RDMA (RoCE & iSER)
Reduces latency, lowers CPU utilization, and boosts overall throughput

Compatible with NAS and PC

The QXG-100G2SF-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 5.1.0 (and later), QuTS hero h5.1.0 (and later). Check compatibility
• Windows®: Windows 11® 22H2, Windows Server 2022® 21H2 (driver required)
• Linux®: Ubuntu® 20.04 LTS (driver required)

Gain up to 200 Gbps connectivity

By virtually bundling two 100 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:

Learn More: SMB 3.0 Multichannel

Note: SMB multichannel is supported by QTS 5.1/QuTS hero 5.1 (or later).

SMB Multichannel

Multiply the available bandwidth (200 Gbps) 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-100G2SF-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.

Note: SR-IOV is supported by specific QNAP NAS models and should work with SR-IOV compatible adapters. Click here to check supported NAS models.

Supports RoCE for Reduced Latency and Enhanced Performance for VM Environments

The QXG-100G2SF-BCM supports RoCE, which can access a network directly in RAM to effectively reduce latency and enhance performance and efficiency for VMware® virtualization environments.

Supports iSER for Improved VM Performance

The QXG-100G2SF-BCM supports iSER, combining iSCSI and RDMA (Remote Direct Memory Access), which can bypass general network drivers, the socket layer, and to directly enter memory buffers of the server and storage. Response time is also reduced to ensure service quality of the NAS.

Build a 100 GbE network environment

Increase your IT performance and productivity by using the QXG-100G2SF-BCM with QNAP’s 100 GbE switch QSW-M7308R-4X, making it easier than ever to deploy a blazing-fast 100GbE network for your business.
