With increasing data volumes, virtualization and I/O-intensive applications, the demands on the network infrastructure are growing significantly. QNAP responds by introducing the QXG-100G2SF-BCM, a new dual-port 100GbE network expansion card for professional environments. The solution is aimed at high-performance NAS systems, servers and data centers where low latency and maximum throughput are critical. The aim is to eliminate existing network bottlenecks and make modern high-speed workloads more efficient.
- Dual-port 100 GbE with QSFP28 for up to 200 Gbps total throughput
- PCIe Gen 4.0 x16 for maximum bandwidth
- Support for RDMA and SR-IOV for virtualization
- Optimized for use with QNAP All-Flash NAS
QNAP QXG-100G2SF-BCM: High-performance network card for modern IT workloads
The QXG-100G2SF-BCM is specifically designed for environments where traditional 10 or 25 GbE solutions reach their limits. Equipped with two 100 GbE QSFP28 ports, the card achieves a combined bandwidth of up to 200 Gbps. The connection via PCIe Gen 4.0 x16 ensures that these data rates can also be processed internally without bottlenecks.
A key feature is the support of RDMA technologies such as RoCE and iSER. These make it possible to transfer data directly between storage and network without placing a heavy load on the CPU. Especially in virtualized environments or with data-intensive applications such as databases, AI workloads or video post-production, this can noticeably reduce latency and increase overall efficiency. This is complemented by SR-IOV, which gives virtual machines direct access to dedicated network resources. This ensures predictable performance and a more even utilization of the hardware.

In combination with a QNAP All-Flash NAS, the QXG-100G2SF-BCM can show its full potential. High IOPS and fast NVMe storage are no longer slowed down by the network, but can also fully develop their performance in the network. This makes the card ideal for demanding enterprise applications and modern data center architectures.
Integration, scalability and deployment scenarios
In addition to pure performance, scalability also plays an important role. The QXG-100G2SF-BCM is part of a growing 100GbE ecosystem from QNAP and can be seamlessly combined with compatible switches such as the QSW-M7308R-4X. This allows businesses to gradually upgrade to high-speed networks without having to replace their entire infrastructure at once.
Typical application scenarios can be found in virtualization hosts, where several virtual machines access central storage systems simultaneously. The high throughput can also significantly shorten time windows in backup and replication environments. In creative workflows, for example when editing high-resolution media content, the card enables smooth data streams even with multiple parallel users.
QNAP deliberately positions the network expansion not as a niche product, but as a building block for scalable enterprise networks. By supporting common standards and offload technologies, the solution remains flexible and future-proof. However, a compatible hardware environment is a prerequisite, as both PCIe Gen 4.0 and corresponding network components are required to exploit the maximum performance.
Conclusion
With the QXG-100G2SF-BCM, QNAP is expanding its portfolio with a powerful dual-port 100 GbE network card that is specifically aimed at professional and data center-related applications. High throughput, low latency and comprehensive virtualization features make it an interesting option for demanding IT workloads. The card is available immediately at a price of 899 euros. For companies looking to significantly increase their network performance, it represents a logical step towards a 100 GbE infrastructure.
