Overview
The QNAP QXG-100G2SF-BCM is a new dual‑port 100GbE network expansion card built to accelerate virtualized environments and all‑flash storage architectures. Using a PCIe Gen 4.0 x16 interface, the card delivers up to 200 Gbps of aggregate throughput. QNAP says the hardware was engineered to eliminate bottlenecks in I/O‑intensive applications and demanding data center environments.
Advanced technologies for virtualization and storage
Integrating the QXG-100G2SF-BCM into enterprise infrastructures lets organizations extract peak performance from all‑flash NAS devices. The card supports offload technologies such as RDMA, including RoCE and iSER, which substantially reduce latency and CPU utilization. According to QNAP’s specifications, that translates into higher overall efficiency, particularly on VMware and other virtualization platforms.
Another key feature is SR‑IOV support, which enables physical bandwidth resources to be assigned directly to virtual machines. This reduces CPU processing overhead and improves performance for virtualized applications.
Scalability and QNAP ecosystem integration
The QXG-100G2SF-BCM was designed to operate seamlessly with QNAP’s network ecosystem, including the 100GbE switch QSW-M7308R-4X. This interoperability simplifies building a scalable, high‑speed IT infrastructure for organizations across industries.
QNAP confirms the card is now available for purchase. The company positions the component as a central element for unifying cybersecurity, artificial intelligence, and data resilience in fast‑evolving digital environments.
