Overview

NVIDIA has launched DSX Air, a cloud-based platform for simulating entire AI factory infrastructure—including compute, networking, storage, and security systems—before physical deployment. This addresses a critical pain point in AI infrastructure planning: the complexity and cost of integrating disparate components across multiple vendors without being able to test configurations in advance.

Key Features

Simulation Capabilities: DSX Air enables full-stack cluster simulation using NVIDIA Spectrum-X Ethernet switches, NVLink technologies, and next-generation hardware like Spectrum-6 switches and NVLink switches for the NVIDIA Vera Rubin platform. Organizations can design, test, and optimize systems before deploying physical hardware.

Checkpoint & History Management:

  • Simulation checkpoints allow users to save snapshots of infrastructure configurations and resume work without losing progress
  • Simulation history provides detailed event logs tracking lifecycle events, user actions, and system changes with searchable filtering for troubleshooting

Enterprise Features:

  • Subscription-based guaranteed capacity without resource limits for large-scale, long-lived simulations
  • Unified account setup through NVIDIA Cloud Account (NCA) with role-based access controls and multi-user/multi-team support
  • Ecosystem partner integrations for interoperability validation across OEMs, ISVs, orchestration tools, and security software

Developer Integration

The platform provides Python SDK and REST APIs for CI/CD pipeline integration, enabling automated simulation instantiation within DevOps toolchains. This allows teams to programmatically verify software and configuration updates before production deployment, supporting Git integration and artifact repositories.

Impact

By enabling pre-production validation without physical hardware dependencies, DSX Air reduces integration risks, compresses deployment timelines, and enhances AIOps efficiency. Organizations can now automate provisioning workflows, test software-defined configurations, and evaluate infrastructure changes in a risk-free environment.
