Accelerated Networking for GPU Fabrics

Power your generative AI, LLM training and GPU-to-GPU workloads at hyperscale

NVIDIA Spectrum-X Ethernet hardware, powered by Cumulus Linux and automated with BE Networks Verity, delivers turn-key Ethernet-based networking designed for east–west GPU cluster fabrics and north–south storage and management traffic – providing unmatched performance, flexibility, and scalability for modern AI environments.

Why Choose Verity to automate NVIDIA Spectrum-X Ethernet?

Automation for Industry-Leading Ethernet for GPUs

Automation for Industry-Leading Ethernet for GPUs

Verity fully automates Spectrum-X Ethernet fabrics that use the latest Spectrum ASICs, offering ports up to 800 Gb/s, ultra-low latency, hardware-accelerated RoCE, and adaptive routing for congestion control - bringing InfiniBand-like performance to standard Ethernet fabrics.

Full-Stack Orchestration & Open Flexibility

Full-Stack Orchestration & Open Flexibility

Verity is built and certified to operate the entire NVIDIA network stack - from Spectrum-X Ethernet switches to Cumulus Linux, NetQ, DOCA, and UFM - this stack ensures seamless integration, predictable performance, and rapid deployment at scale.

Turnkey NVIDIA Ethernet Operations

Turnkey NVIDIA Ethernet Operations

Verity automates the Cumulus Linux NOS with prebuilt templates, reference designs, and operational workflows. Features like VRFs, VLAN/VXLANs, EVPNs and ESI enable fast, scalable deployment and granular control of ports to support multitenancy.

Resilient AI Fabrics with BGP PIC

Resilient AI Fabrics with BGP PIC

The Spectrum-X Ethernet fabric supports BGP PIC, which precomputes backup paths and ensures predictable convergence even in massive GPU clusters - making large-scale LLM training resilient to link failures.

Intelligent Routing for Storage Acceleration

Intelligent Routing for Storage Acceleration

Hardware-accelerated adaptive routing mitigates traffic congestion and boosts storage fabric performance. Combined with BlueField-3’s out-of-order packet reassembly, Spectrum-X handles large “elephant flows” like LLM checkpoints with ease.

NVIDIA Reference Architecture

East-West & North-South Networks

NVIDIA Reference Architecture: East-West & North-South Networks

East-West (E-W) AI Compute Fabric

High-throughput, low-latency fabric connecting GPU nodes using Spectrum-X Ethernet switches, SuperNICs (Connect-X, Bluefield), and Cumulus Linux - ideal for distributed training and inference.

North-South (N-S) Management & Storage Fabric

Layered Ethernet networks dedicated to storage, orchestration, and management, isolated from GPU traffic. Built with Spectrum-X Ethernet and managed with Cumulus Linux, leveraging features like MLAG, NVMe-over-Fabrics, RoCE, and telemetry via NetQ/WJH.

Digital Twins & Validated Configurations

Using NVIDIA Air, customers can use Verity to evaluate the Spectrum-X Ethernet Validated Solution Stack. Air's virtual topologies allow you to instantly deploy networks with automated configurations, text automated workflows, and perform complex observability functions without dedicated hardware.

Programmability & Ecosystem Integration

Verity integrates Spectrum-X Ethernet network fabrics with 3rd party tools using an OpenAPI 3.0 compatible set of REST endpoints. Using these endpoints, operators can leverage native Terraform, Ansible and Netbox plugins to operate the network with whatever software they want.
