Aviz Networks outlines ONES automation for Spectrum X fabrics

ONES Fabric Designer automates Day 0 planning for NVIDIA Spectrum X Ethernet fabrics, generating validated IPCLOS underlays, RoCEv2 Quality of Service (QoS), and server Network Interface Controller (NIC) configurations to produce production-ready designs for large-scale Artificial Intelligence (AI) deployments.

Research overview

Aviz Networks describes ONES as an intent-driven engine that converts high-level inputs such as scalable unit size, Graphics Processing Unit (GPU) count, and IP ranges into a full Spectrum X fabric blueprint. The tool produces a validated configuration prior to hardware deployment to reduce manual Day 0 activity.

Key findings

ONES automates spine-leaf IPCLOS topology generation, Border Gateway Protocol (BGP) EVPN and control-plane settings, interface assignments, and port breakouts. The design output also covers server NIC provisioning for NVIDIA BlueField and ConnectX devices and applies RoCEv2 QoS profiles including Power Factor Correction (PFC) and ECN settings.

Technical breakdown

The underlay generation includes spine and leaf configurations sized to GPU and server scale, complete BGP peering with AS number allocation, and consistent interface parameters such as MTU and IP addressing. These elements are produced as a coherent plan rather than as isolated configuration fragments.

Server-side automation configures SuperNIC features, hardware offload and acceleration settings, and performance tuning options such as adaptive retransmission and inter-packet gap adjustments. RoCEv2-specific elements include buffer tuning, PFC, ECN, and DSCP trust state alignment across ports.

Operational impact

The vendor states tasks that previously required extensive Command-Line Interface (CLI) work are generated in minutes, enabling a shorter Day 0 workflow and a single, validated configuration artifact. ONES also applies consistent switch port settings, Virtual LAN (VLAN), MTU, and QoS parameters and uses Link Layer Discovery Protocol (LLDP) validation to confirm physical connectivity.

Deployment and validation

The workflow supports virtual verification in NVIDIA Adaptive Incident Response (AIR) to exercise the design under load before committing to hardware and uses Zero Touch Provisioning to deploy the final configuration. The output is described as a production-ready configuration that combines underlay, QoS, and server integration into one design package.

The brief summarizes that ONES automates intent-driven design and validation for Spectrum X AI fabrics and that the resulting configurations are intended to streamline Day 0 activities for enterprise deployments. This “Blog Signals brief” is a fact-based summary of the vendor blog.
