Evidence
Second, some customers, namely Meta, may look to integrate their network switch rack with BBU and CBU shelves for efficiency and peak shaving. This allows more CBU and BBU capacity that wouldn’t have been able to fit in the GPU rack. The BBU/CBU and switch rack will be connected to the GPU rack with 50V horizontal busbars. Meta calls this the high power rack, discussed at OCP.
Context After
We have more detailed power and architecture details in our VR NVL72 Component BoM and Power Budget Model ↗.

② Atomic Claim
Meta calls the described combined BBU/CBU and network-switch configuration the high power rack.
