OCP Open Data Center design targets for the heaviest single rack and for an ML rack plus power sidecar
8,000 lb single rack (28 × 48 in); 15,000 lb ML rack + sidecar (56 × 48 in)recommendation
| Value kind | recommendation — Recommendations are design guidance, not measured facts; validate them against the project boundary conditions. |
|---|---|
| Scope | Footprint pressure, not a uniform floor-design load: 8,000 lb over 28 × 48 in (9.33 ft²) is about 857 lb/ft², and 15,000 lb over 56 × 48 in (18.67 ft²) is about 804 lb/ft². Handling equipment counts in the moving load. Platform wet weights (GB200/GB300 NVL72 about 3,000–3,300 lb, Vera Rubin NVL72 about 4,000 lb) are separate figures. |
| Caveat | Design targets for 2027–2028 AI/ML systems in a voluntary multi-vendor specification (AMD, Google, Meta, NVIDIA); not measured or shipping racks. |
