A Reliability Control Plane for AI Racks
Projection: Rack-scale AI systems will add a reliability control plane that predicts degraded links and components, then coordinates graceful recovery before jobs fail. NVIDIA already documents resilient NVLink operation, partial-rack support, and hot-swappable switch trays; Broadcom's Tomahawk roadmap adds high-capacity switching. Predictive operations remain the forecast, not an observed deployment.
Why this idea is here
What the evidence establishes.
Source-backed premises: NVIDIA documents NVLink resiliency features, operation with partially populated racks, and hot-swappable switch trays; Broadcom documents a 102.4-Tbps Tomahawk switch for AI networks. Editorial projection: predictive failure detection and coordinated recovery become a rack reliability control plane; neither source shows that control plane deployed.
