Aviz Networks ONES Fabric Designer automates NVIDIA Spectrum X fabric Day 0 design

Aviz Networks’ ONES Fabric Designer automates Day 0 design for NVIDIA Spectrum X AI fabrics, generating IPCLOS underlays, BGP-based control-plane settings, RoCEv2 QoS, and server NIC configurations with validation before hardware deployment.

Research Overview

The post frames AI network fabric design as a Day 0 task where architectural choices affect performance and scalability across the system. It positions NVIDIA Spectrum X as an Ethernet fabric for AI while stating that teams need a method to convert design intent into deployable configurations.

ONES Fabric Designer is described as an intent-driven workflow that replaces manual configuration effort with automated generation and a validated plan. The author links the approach to reducing time spent on configuring topologies and fabric parameters.

Key Findings

ONES Fabric Designer converts high-level inputs into a complete Spectrum X fabric blueprint and provides a validated design prior to hardware deployment. The article says the tool eliminates manual assignment of IPs, BGP AS numbers, and other fabric parameter setup.

The post states that automation covers IPCLOS underlay construction, RoCEv2 QoS enforcement, and server node integration. It also claims that tasks described as taking days of CLI-based work can be generated in minutes.

Technical Breakdown

The post describes ONES as an intent-driven engine that takes inputs such as scalable unit size, number of GPUs, and starting IP address ranges. It says these inputs drive automatic generation of the full design and delivery of a validated plan before deployment.

For the IPCLOS underlay, the article says ONES automates spine and leaf configuration based on GPU and server scale, including BGP peering with AS number allocation and resilient control plane settings. It further says it generates consistent interface configurations such as port breakouts, MTU, and IP assignment.

Operational Impact

On the server and NIC side, the post says ONES extends automation to NVIDIA BlueField and ConnectX SuperNICs and configures RoCEv2 parameters including PFC and ECN. It also lists hardware acceleration and offload features and performance tuning elements such as adaptive retransmission and Inter Packet Gap adjustments.

For QoS, the article states ONES delivers “zero-touch” RoCEv2 QoS by applying validated RoCEv2 QoS profiles, setting trust states such as DSCP, and ensuring consistent buffer, PFC, and ECN settings across ports. It connects this to lossless network behavior intended for high-speed GPU-to-GPU communication.

Conclusion

The blog presents ONES Fabric Designer as an intent-driven automation layer for designing, validating, and preparing NVIDIA Spectrum X AI fabrics, covering IPCLOS underlay generation, RoCEv2 QoS, and server-side integration before hardware provisioning.
