IREN Limited announced that it is working with BE Networks to leverage NVIDIA DSX Air to simulate and validate the network architecture supporting IREN Limited's upcoming deployment of more than 50,000 NVIDIA Blackwell Ultra GPUs. The initiative will enable IREN Limited and BE Networks to utilize a production-representative digital twin of IREN Limited's AI cloud environment before the physical infrastructure is deployed. Using NVIDIA DSX Air, the companies can model the behavior of large-scale GPU clusters, validate network topologies, test automation workflows, rehearse changes and identify issues before they impact production systems. NVIDIA DSX Air is a platform that logically simulates a full AI factory ecosystem of NVIDIA and partner technology to simplify and accelerate complex AI deployments, providing a high-fidelity simulation of NVIDIA AI compute, NVIDIA Spectrum-X Ethernet and NVIDIA NVLink scale-up networking.

NVIDIA DSX Air gives infrastructure teams the ability to simulate these complex environments in advance, including compute, networking, storage, orchestration and security layers. BE Networks will support the initiative with its Verity automation and orchestration platform, helping IREN Limited translate validated designs into repeatable deployment workflows across Day 0 design, Day 1 turn-up and Day 2 operations. The result is a modern deployment model for AI cloud infrastructure: simulate first, validate at scale, automate the rollout and deploy with confidence.
