Context Before

This translates to four NVLink Switch chips per tray on 9 switch trays, or 36 NVLink Switch chips in each rack.

Evidence

Each VR NVL72 Switch tray contains four NVLink 6 Switch ASICs and one system management module.

Context After

The design of the Rubin NVLink 6 Switch tray is also simpler and relatively seamless compared to the first Oberon NVLink 5 Switch released for GB200 because Rubin NVLink 6 Switch trays will not use flyover cables. As such, all NVLink signals will run over the PCB.

② Atomic Claim

每個 VR NVL72 Switch tray 包含 4 顆 NVLink 6 Switch ASICs，以及 1 個 system management module。
