Context Before
Source: OCP, Meta, SemiAnalysis
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.
Evidence
We have more detailed power and architecture details in our VR NVL72 Component BoM and Power Budget Model
Context After
Networking: NVLink 6, Rubin Scale Out
NVIDIA’s gen-on-gen innovations are evolutionary and not revolutionary. With GPU scale-up and scale-out bandwidth doubling approximately every 18 months, the copper infrastructure in NVIDIA racks are being innovated to accommodate higher bandwidth workloads. Scale-up network infrastructure will eventually involve optics to build larger world sizes, but that is the topic of a separate article.
