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 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.

Evidence

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.

Context After

We will discuss the logistical implications of much more limited hyperscaler customisation and the assembly supplier landscape.

② Atomic Claim

報告也會討論 VR NVL72 的主要 network，包括 NVLink 6 scale-up network 與 backend scale-out network。
