Armada has been an NVIDIA DSX Air user since late 2024, and we have derived significant benefits from its ability to simulate Spectrum-X Ethernet environments for both internal development and customer proof-of-concept initiatives. NVIDIA DSX Air has enabled us to validate networking configurations and topologies, test multi-tenant configurations, and accelerate Bridge software deployments (Bridge is an on-prem Armada software product that provides multi-tenancy and cloud services on GPU hardware) without relying exclusively on physical hardware.

We are excited about the launch of NVIDIA DSX Air and the expanded AI Factory digital simulation capabilities it introduces. This next evolution unlocks multiple use cases for Armada and our customers — driving measurable improvements across development velocity, PoC efficiency, operational stability, OPEX reductions and go-to-market. The key benefits are described below.

1. Development Velocity Without Hardware Bottlenecks​

If you're building GPU cloud management software like Bridge, you are constantly running into hardware constraints. Testing against large-scale topologies, DPUs and advanced NVLink fabrics, as well as next-gen GPUs isn't trivial.

With NVIDIA DSX Air, we can simulate full AI Factory environments — including GPUs, NVLink, Spectrum-X Ethernet switches, ConnectX SuperNICs, and BlueField DPUs — while continuing to validate against physical production-grade clusters.

That means:

  • No lab contention
  • No waiting for hardware allocations
  • No waiting for the latest generation GPU
  • Ability to test at scale (including configurations customers may run before we ever see them)

For Bridge, this translates to faster releases, better validation, and stronger resiliency. Simulation accelerates validation, while hardware testing ensures production-grade performance and interoperability.

With the advent of AI Grid, NVIDIA DSX Air will become even more valuable. We will be able to simulate multiple edge sites and rapidly develop our policy-based application placement capabilities.

2. Removing Friction from Bridge Evaluations​

Today, most AI factory or multi-tenancy PoCs depend on real infrastructure. That slows everything down:

  • Provision racks
  • Provide access
  • Isolate environments
  • Justify costs

NVIDIA DSX Air breaks that dependency. Armada can provision simulated AI factory environments where customers can evaluate Bridge and its numerous capabilities:

  • Multi-tenancy policies
  • Hard isolation between tenants
  • IaaS (BMaaS, VMaaS, storage, network)
  • PaaS (managed Kubernetes)
  • AIaaS (LLMaaS, Jupyter Notebooks, managed SLURM, Kubeflow)
  • Billing
  • User management
  • NVAIE and 3rd party AI software

This allows early-stage validation without waiting on hardware availability, compressing PoC timelines from months to weeks — before transitioning to hardware-based validation with greater confidence. That shortens sales cycles for us. More importantly, it lowers psychological friction. When customers can "try before they rack," adoption accelerates. Once this phase completes, the customer can ultimately move to a hardware based PoC.

3. Production Digital Twins for Operational Safety​

This is where the long-term value resides. Bridge customers operating AI factories at scale deal with:

  • Complex tenant segmentation
  • Reserved vs on-demand workloads
  • Brownfield network configurations

Making changes in production is risky. With NVIDIA DSX Air, customers can build a high-fidelity digital twin of their environment and:

  • Confirm that Bridge coexists with manual configurations
  • Test new configuration changes safely
  • Validate policy updates
  • Simulate tenant onboarding
  • Expand model capacity expansion
  • Run and identify failure scenarios
  • Detect configuration drift

NVIDIA DSX Air features extensibility, which will allow us to model our modular datacenters branded Galleon. With Galleon modeling, we will be able to use our datacenter infrastructure management software to simulate actions such as changing chillers on the digital twin before applying the same action to the physical environment.

Instead of configure and hope, customers can simulate and verify. For brownfield environments especially — where some multi-tenancy rules were implemented manually — this reduces the fear of Bridge "messing up" existing configurations. Customers can easily reduce costly configuration errors that can result in six-figure downtime events.

Operational risk is one of the biggest hidden OPEX drivers in AI infrastructure. Digital twins reduce that risk.

4. A New Distribution Channel for Bridge​

The NVIDIA DSX Air blueprint marketplace introduces another dimension. Bridge based pre-built blueprints will be instantiated within the NVIDIA DSX Air environment; customers can experience our value immediately at a fraction of the cost compared to the hardware — integrated with simulated GPU, networking, storage, and security stacks. Now we go beyond simulation to becoming discoverable.

It positions Bridge inside the AI factory design phase — not after hardware has already been deployed.

The Bigger Picture​

For Bridge, NVIDIA DSX Air unlocks:

  • Faster development
  • Faster sales cycles
  • Safer production evolution
  • Stronger ecosystem presence

AI factories are the future of infrastructure, and high-fidelity digital twins will become standard practice. And Bridge will be native to that future — not bolted on after the racks are live.
