September 23, 2025ONES & SONiC
Summary:
- Spectrum-X provides high-performance Ethernet fabrics for AI workloads.
- ONES Fabric Designer automates Day-0 design, underlay config, and server integration.
- Features include intent-based design, IPCLOS automation, RoCEv2 QoS, and server NIC optimization.
- Result: validated, production-ready configs in minutes, not weeks.
Introduction:
Building an AI-ready network fabric is one of the most complex tasks in infrastructure engineering. With NVIDIA Spectrum-X providing the hardware backbone, the challenge shifts to orchestration: How do you translate design intent into a production-ready fabric without weeks of manual work?
That's where the Aviz ONES Fabric Designer comes in. It transforms Day-0 design into a fast, error-free, intent-driven process, automating IPCLOS topology, QoS, and server node integration.
How Does ONES Simplify Spectrum-X Fabric Deployment?
ONES automates design and configuration with intent-driven blueprints, ensuring validated, production-ready Spectrum-X fabrics that are lossless, resilient, and AI-optimized.
How Does Intent-Based Design Work in ONES?
- Define high-level inputs: Scale Unit size, GPU count, IP ranges.

- Auto-generate full fabric design and configs.
Figure 2: Auto-generated fabric design and configuration
- Validate topology before deployment.
Outcome: A logical blueprint that eliminates manual IP/BGP mapping.
How Does ONES Automate IPCLOS Underlay?
- Spine/Leaf configs: Auto-calculated per GPU/server count.
- BGP automation: ASN assignment + peering configs.
- Interface setup: Ports, IPs, MTU consistent across fabric.
- Server NIC configs: RoCEv2 tuning, PFC/ECN, hardware offloads, adaptive routing.

How Does ONES Ensure Lossless RoCEv2 Performance?
- Auto-applies best-practice QoS profiles for RoCEv2.
- Consistent DSCP trust and buffer settings across ports.
- Eliminates packet drops that can derail AI training jobs.
Spectrum-X fabrics are InfiniBand-class, out of the box.
How Does ONES Integrate GPU Servers and SuperNICs?
- Auto-configures switch ports (VLANs, MTU, QoS).
- Validates connections via LLDP.
- Extends orchestration to BlueField-3 SuperNICs for end-to-end tuning.
Ensures GPUs connect flawlessly to the fabric with zero manual intervention.
Conclusion:
With ONES Fabric Designer, Day-0 Spectrum-X deployment becomes:
- Intent-driven and blueprint-based.
- Automated for IPCLOS, QoS, and NIC configs.
- Validated via NVIDIA AIR before hardware deployment.
- Zero-touch provisioned for fast, reliable rollout.
ONES turns fabric design into a repeatable, intelligent process that accelerates AI infrastructure deployment.
