AI factories combine GPUs, CPUs, switches, DPUs, and SuperNICs with schedulers and security controls, making validation before hardware arrival critical. NVIDIA DSX Air provides a node-based digital twin that models hardware topology and software stack, allowing teams to validate supported configurations in a safe environment before production. AI agents interrogate the twin, run supported configuration and security checks, compare results with organizational policy, and produce evidence-based reports. The simulation supports Day 0 through Day 2 operations and integrates with NVIDIA Brev for on-demand GPU compute to run AI services like Video Search and Summarization. This governed automation model uses human-in-the-loop gates to ensure agents explore in the sandbox while production changes require approval, enabling continuous improvement.

Graphs encode relationships and provide scaffolding for causal inference and compositional reasoning, which is essential for AI agents reasoning over complex networks. The post traces the evolution of graph intelligence from passive topology models to active agentic reasoning, culminating in a three-pillar approach for root cause analysis. The approach combines a continuously synchronized network digital twin graph with a cascaded pipeline of graph algorithms—decomposition, clustering, and centrality ranking—that narrow the search space. An agentic orchestration layer selects and composes these algorithms adaptively based on failure characteristics, performing complexity triage and consulting an incident knowledge base. The system achieved root cause analysis in minutes on commercial networks, demonstrated with NTT DOCOMO at MWC.
