# How ONES Automates Spectrum-X Fabrics from Design to Deployment

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.

- 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.
