Engineering the Exascale AI Factory: GIGAPOD NVIDIA Vera Rubin NVL72

Enterprise AI has reached a critical inflection point. As multi-modal models and complex agentic workflows replace basic request-and-response patterns, conventional rack architectures built around individual 8-GPU servers are hitting an infrastructure wall. Today's limits are no longer defined by raw FLOPS, but by memory domain coherent boundaries, interconnect latency, and thermal dissipation ceilings.

This white paper introduces the GIGAPOD NVIDIA Vera Rubin NVL72 a factory integrated, turnkey rack-scale blueprint designed specifically for trillion-parameter agentic AI. Co-engineered by GIGABYTE and NVIDIA, the solution unifies 72 NVIDIA Rubin GPUs and 36 NVIDIA Vera CPUs into a single, cohesive 20.7 TB HBM4 memory domain via a 6th-Gen NVLink 260 TB/s all-to-all switch fabric. Powered by high-density Direct Liquid Cooling (DLC) supporting up to 240 kW per rack, GIGAPOD captures over 92% of rack heat, operating stably with 45 degrees celcius warm water to eliminate energy-intensive facility chillers.
