Context Before
Power sloshing between Vera and Rubin is still present, a feature carried over from GB300. This enables more efficient power planning by sharing the 4800W provided amongst both GPU and CPU. In GPU demanding loads, 2300W goes to each GPU leaving 200W for the CPU. Vera can then dynamically boost to higher power when GPU demand drops to help minimize GPU idle time while not overprovisioning power.
Evidence
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.
Context After
50VDC is stepped down to 12VDC at the PDB then, via a copper 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.
② Atomic Claim
對 chassis 前端的 CX-9、BlueField-4 與 management modules，PDB 會分別供應 12VDC。
