Accelerating Ai Networking With Nvidia Spectrum X And Aviz Ones - Resource | Aviz Networks | Aviz Networks
ONES + NVIDIA Spectrum-X Ethernet | Intelligent AI Fabric Orchestration
A unified platform to design, deploy, and operate AI-ready Ethernet fabrics
February 2, 2025
Overview
The ROI of AI and HPC clusters depends on the high-performance network fabric that supports them. Training large-scale AI models and deploying multi-tenant AI inference clusters requires ultra-fast GPU-to-GPU and GPU-to-storage communication, ultra-low latency, lossless data transfer, and seamless scalability. NVIDIA Spectrum-X Ethernet provides this foundation with Spectrum-4 Ethernet switches, NVIDIA SuperNICs, and NVIDIA GPU Platforms.
Aviz ONES (Open Networking Enterprise Suite) complements Spectrum-X Ethernet by providing intelligent multi-tenant orchestration, simplifying day-to-day operations, and enabling comprehensive monitoring across the fabric. ONES also supports customers to expand their AI factory footprint over time without impacting existing tenants. Together, ONES and Spectrum-X Ethernet allow enterprises to achieve predictable AI performance with greater simplicity and confidence.
Spectrum-X Ethernet Fabric Architecture
ONES is fully aligned with the NVIDIA Spectrum-X Ethernet Reference Architecture (RA). At present, ONES supports RA 1.3, which is built on:
01
NVIDIA GPU Platforms
The industry's leading AI compute platform.
02
Spectrum-4 Ethernet Switches
High-density Ethernet switches optimized for AI networking.
03
BlueField-3 SuperNICs
Hardware acceleration for RoCEv2 and advanced telemetry.
As NVIDIA evolves the Spectrum-X Ethernet RA, ONES will continue to align with future RA versions and their components — ensuring that enterprises can confidently adopt the latest GPU, switch, and NIC innovations while maintaining consistent orchestration and operational workflows.

This combination delivers high-performance Ethernet networking, providing a lossless, ultra-low latency GPU fabric that is purpose-built to accelerate AI workloads, maximize GPU utilization, and ensure predictable performance at scale.
Orchestrating AI Fabrics with ONES
Traditional data center networks were not built for AI, often struggling with multi-tenancy, lossless transport, and lifecycle operations. A modern AI Factory is rail-optimized, combining an East-West GPU fabric for high-bandwidth compute, a North-South fabric for CPU, storage, and external user access.
The Scalable Unit (SU) is the modular building block combining up to 32 GPU Nodes and the required leaf switches for the North-South and East-West fabrics. The maximum size of a single AI factory deployment with a 2-tier leaf-spine network is 32 SUs with a total of 1,024 GPU Nodes and 8,192 GPUs. ONES orchestrates across all hosts and SUs consistently, enabling smooth deployment and seamless growth from hundreds to thousands of GPUs.

Addressing Network Challenges
Conventional network tools fall short in meeting the demands of AI fabrics. ONES addresses the gap with:
Intelligent Orchestration
Build validated topologies from high-level inputs (GPU count, IP ranges, SU definitions).Day-to-Day Operations
Tenant creation, GPU-aware provisioning, and policy-driven workflows via GUI.Monitoring & Observability
Real-time visibility across switches, NICs, and GPUs with integrated telemetry.Lifecycle Management
Support for RMA, box replacements, and drift detection.

Day-0: Orchestration & Design
01
Simplified Inputs
Define SU count, subnets, and storage type. Provide customers with the option to design for future growth, minimizing operational impact when expanding the AI factory footprint.
02
Fabric Intent
Define whether the AI fabric is built only for GPU-to-GPU traffic (East-West) or for GPU traffic plus external ingress/egress (East-West + North-South) at Day-0.
03
Intent-based Design
ONES auto-generates validated configs for underlay, QoS, and NICs.
04
Pre-deployment Validation
Use NVIDIA AIR to simulate topologies before rollout.
05
Zero-Touch Provisioning (ZTP)
Push configs across switches and servers consistently. Provide customers with the option for both greenfield and brownfield deployments (e.g., validate existing configurations).

Spectrum-X Ethernet Orchestration
ONES provides a unified interface for designing, viewing, and managing AI factory topologies. The Fabric Designer visualizes your Scalable Units, network layers, and device relationships — making complex AI factory architectures easy to understand and manage.
NVIDIA Air Integration
Validate your AI factory designs end-to-end using NVIDIA Air digital-twin simulation. ONES integrates directly with NVIDIA Air, allowing you to simulate topologies, test configurations, and verify operational readiness before production rollout.
ONES: Day-1 Multi-Tenant Operations
01
Tenant Management
Create isolated tenants using VXLAN/EVPN with policy control.
02
GPU-aware Provisioning
Align network resources with compute.
03
Role-based GUI Orchestration
Simplifies operations without CLI.
