Context Before
Read full story ↗
Power sloshing between Vera and Rubin is still present, a feature carried over from GB300 that we covered in our article above. 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.

Compute Tray: Mechanical
The mechanical components of the VR NVL72 compute tray are slightly more sophisticated than that of the Grace Blackwell. At the front of the chassis, there is a mechanical structure that separates the front into three sections, with the left and right sections housing the Orchid modules and the middle sections housing the BlueField-4, the power delivery and the management modules. Each of the modules will also have a small metal chassis. The mechanical structure provides a simple guiding mechanism that guides the modules to a blind mate process with the midplane and the internal manifolds.
