NVLink 6 Switch - Line hint:
103
Context Before
Evidence
While the rack-level switching bandwidth has doubled, the number of NVLink Switch chips per rack has also doubled to 36, with each switch tray now housing 4 Switch chips.
Context After
This means the new NVLink 6 Switch chip has the same 28.8T bandwidth as NVLink5 Switch, with half the number of ports but running at double the rate using ‘400G’ bi-directional SerDes. This allows the high bandwidth switch design to remain as a single monolithic die, saving on design complexity.
② Atomic Claim
Rack-level switching bandwidth 加倍的同時，每 rack 的 NVLink Switch chips 數量也加倍至 36 顆；每個 switch tray 現在配置 4 顆 Switch chips。
