In fact, if you have not already noticed – there are strong parallels between the X800-Q3400 switch (non-CPO) explained earlier in the article and a CPO switch in that both facilitate high-radix, multi-plane networking architectures while encasing within the box complex cabling that saves customers on the hassle of cable management.
Outside of the NVIDIA ecosystem, the main switch ASIC players are Broadcom, which will be manufacturing the Tomahawk 6 and Tomahawk 6 CPO ASICs, as well as Cisco, which recently announced the G300 102.4T ASIC. There are two flavors of hyperscaler backend network deployments:
② Atomic Claim
在原文所述假設情境中，隨著每顆 GPU bandwidth 提升到 3.2T，可以設想使用 SN6800 switches 的 4-plane network：每顆 3.2T GPU 分成 4 路，以每條 800G link 連到 4 個不同 switch boxes。
