High-Performance Low-Profile 25GbE SmartNIC enabling PCIe Gen4 acceleration with the QXG-25G2SF-CX6
The QXG-25G2SF-CX6 is a PCIe 4.0 x8, low-profile dual-port 25GbE SFP28 SmartNIC designed for modern server and NAS platforms where deterministic throughput and low latency are architectural requirements. Built on the NVIDIA ConnectX-6 Lx EN controller, it aligns well with virtualization-dense CPU hosts and storage nodes by reducing host CPU cycles spent on encapsulation, segmentation, and steering.
By pairing 2 x 25GbE SFP28 uplinks with hardware offloads for SR-IOV and overlay protocols, the QXG-25G2SF-CX6 improves east-west traffic efficiency for hypervisors and container fabrics while maintaining compatibility with 10GbE and 25GbE speed profiles. RoCE (RDMA over Converged Ethernet) support enables lower-latency data movement for storage networking and HPC-adjacent workloads, and PXE boot support simplifies stateless provisioning and fleet rollout in standardized racks.
Why Choose the QXG-25G2SF-CX6?
The QXG-25G2SF-CX6 delivers a practical density-to-performance ratio: 2 high-speed ports in a single low-profile slot, backed by PCIe Gen4 bandwidth and SmartNIC-class offloads that preserve compute headroom for applications. It scales cleanly from single-node upgrades to multi-node fabrics, supporting predictable network behavior under virtualization and overlay-heavy traffic while keeping deployment straightforward across mixed server and NAS estates.
QNAP focuses on integration-driven engineering, ensuring the adapter’s firmware and platform behavior fit enterprise operational standards for reliability, lifecycle management, and consistent connectivity in data centre environments.
Key Applications:
- 25GbE server and NAS uplinks
- iSCSI and storage networking
- Virtualization with SR-IOV
- Overlay networks (VXLAN/NVGRE/Geneve)
- RoCE-enabled low-latency fabrics
