Context Before

In the sections below, we will discuss the 6 silicon products of the Vera Rubin platform at the silicon level. Then, we will discuss the rack and

Evidence

compute tray evolution from Grace Blackwell to Vera Rubin from the design perspective and the implication to components: cables, connectors, PCB, thermal, mechanical, and power.

Context After

Next, we will discuss the major networks of the VR NVL72 system, namely the scale up NVLink 6 network and the backend scale out network. We will discuss the logistical implications of much more limited hyperscaler customisation and the assembly supplier landscape.
