Context Before

For the VR NVL72 reference design, the power delivery infrastructure at the rack level includes four 110kW power shelves. The VR NVL72 system has a TDP up to 220kW for the 2300W Rubin TDP SKU.

Evidence

The design with four 110kW power shelves is an N+1 redundancy approach.

Context After

Each 110kW power shelf is 3U tall and includes six 18.3kW PSU with built in capacitors in the PSU. Each power shelf receives three phase 415VAC-480VAC of power from two 100A whips.

② Atomic Claim

採用 4 個 110kW power shelves 的設計，是 N+1 redundancy approach。
