|---|---|
| Scope | Three separate vendor profiles, not one facility design basis. NVIDIA's enterprise reference architecture (March 2026) says a full rack needs up to 142 kW. Lenovo (LP2357, 30 August 2026) lists 135 kW TDP and up to 155 kW peak, with about 90% of heat going to liquid and 10% to air. HPE's QuickSpecs (8 September 2026) list 132 kW nominal and about 155 kW EDPp, and recommend 192 kW busway provisioning. |
| Caveat | Size power distribution to the peak and provisioning basis of the OEM configuration you buy, cooling to its liquid and air duties, and energy and TCO models to its operating profile. |
