The digital landscape is rapidly evolving with soaring data rates, complex workloads, and the rise of cloud-native architectures, driving network demands to expand faster than ever. Modern networks require scalable SmartNICs that seamlessly scale from 10G to beyond 100G, enabling efficient bandwidth handling and avoiding costly hardware upgrades. These SmartNICs offload compute-intensive tasks, enhancing CPU performance and system efficiency, making them vital for futureproofing infrastructure and maximizing ROI. SmartNIC technology has advanced from 40 Gbps per port to now supporting up to 200 Gbps and beyond, keeping pace with Ethernet standards like 200G, 400G, and 800G Ethernet—empowering enterprises to build high-speed, scalable networks for modern workloads.
iW-Fibre SmartNICs: Designed for the Future

Architecture — how scalability is achieved
Modern data centers demand adaptability across evolving network standards and workloads. The iW-Fibre SmartNIC family is architected around three core scalability levers that ensure sustained performance growth without hardware redesigns:
- Multi-rate transceivers & PHY/PCS/FEC
Agilex™ 7 SerDes channels support both 50G and 100G PAM4 lanes, enabling flexible aggregation configurations such as:
- 4×50G (200G)
- 8×50G / 4×100G (400G)
- 8×100G (800G)
Standards-compliant PCS and FEC blocks (including RS(544,514)) allow interoperability across IEEE 802.3cd, 802.3bs, and 802.3df standards, ensuring forward compatibility and hardware reusability.
- FPGA datapath capacity & reconfigurability
The FPGA fabric is the heart of iW-Fibre scalability—housing programmable packet parsers, pipelines, schedulers, and accelerators. Scaling to higher bandwidths is achieved by widening datapaths and leveraging available logic and DSP resources.
This modular reconfigurability allows system architects to tailor acceleration for specific workloads such as DPDK offloads, P4 processing, or security acceleration, ensuring performance efficiency at every scale.
- Scalable host interface
With PCIe Gen4/Gen5 ×16 connectivity, the SmartNIC ensures sufficient host bandwidth for each configuration:
- 200G operates efficiently on PCIe Gen4
- 400G and 800G leverage Gen5 or multiple PCIe domains for balanced throughput
This architecture guarantees that host communication never becomes a bottleneck, even as data rates double or quadruple.
- Software-Defined Upgrades: Field Programmable Evolution
A major advantage of iW-Fibre SmartNICs is their field upgrade model. By reprogramming the FPGA bitstream and updating PHY/PCS/FEC configurations, customers can evolve from 200G to 800G capability without redesigning hardware—dramatically reducing engineering effort and time-to-market.
Built for Modern Workloads
In data centers, where data demands are soaring, 800G Ethernet enables high-speed connectivity and scalable storage infrastructures. Social media platforms can use iW-Fibre SmartNICs to efficiently manage massive volumes of user-generated content such as photos and videos.
For virtualization and containerization, iW-Fibre SmartNICs with 200G/400G/800G Ethernet enable high-bandwidth, low-latency support for virtual machine migration and container communication. Cloud providers can leverage them to accelerate virtualized workloads and enhance infrastructure efficiency.
SmartNIC Integration and Cost Considerations
SmartNICs integrate processors and memory, which increases their cost compared to standard NICs, often by two to three times. This integration enables custom software and advanced network services to run directly on the SmartNIC, providing flexibility and programmability. Solutions built solely on embedded CPUs are easy to develop but may struggle to deliver the required performance, latency, and jitter characteristics.
Agilex™ 7 FPGA-based SmartNIC from iWave addresses these challenges by providing deep programmability, hardware acceleration, and workload-specific optimization. While traditional FPGA designs have been associated with higher power consumption and lower logic density, iW-Fibre SmartNICs offer a balanced architecture that combines high performance, scalability, and efficiency for next-generation networks.
Built to scale, Ready for future
Scalability from 200G → 400G → 800G is achievable without wholesale hardware replacement when the SmartNIC architecture is built around reconfigurable PHY, a programmable FPGA datapath, scalable host interfaces, and modular offload engines. iW-Fibre SmartNICs on Agilex™ 7 demonstrate this model: standards-aligned PCS/FEC reuse, verifiable FPGA resource headroom, and clear hardware artifacts that prove multi-rate scalability.
For operators, the result is clear: deploy once, scale in place, and evolve dataplane capabilities, reducing total cost of ownership while meeting the performance demands of AI-era data centers.
