Hot-Swappable AI Rack Modules
Projection: NVIDIA documents resilient rack fabrics, partial-rack operation, and modular switching; AMD publishes open rack-scale systems and a multigeneration roadmap. Accelerator, switch, memory, or cooling trays may become serviceable modules. The thesis is proven by component replacement that preserves useful cluster operation, not by modular packaging alone.
Why this idea is here
What the evidence establishes.
NVIDIA documents rack-scale all-to-all GPU fabrics, rising bandwidth, resilience features, and NVLink Fusion for hybrid systems; AMD documents the Helios rack-scale platform with Instinct MI450X GPUs, Venice CPUs, advanced networking, and ROCm, on track for second-half 2026 deployments. These are source-backed premises for this projection; they do not by themselves prove broad adoption or the eventual outcome.
