Evidence

This enables more efficient power planning by sharing the 4800W provided amongst both GPU and CPU

Context After

For the modules at the front of chassis - CX-9,BlueField-4, and management - the PDB feeds 12VDC of power to each of the modules. 50VDC l down to 12VDC at the PDB then, via a coper busbar device, the PDB feeds 12VDC to its neighboring modules. The power connector of CX-9 is located near the Paladin HD2 at the top of the modules.

Compute Tray: Mechanical

② Atomic Claim

此功能讓 4,800W power 可以在 GPU 與 CPU 間共享，提高 power planning 效率。
