Context Before

We think that the SN6800 switch with 512 ports of 800G will be quite attractive to Neoclouds because it simplifies deployments. Similar to the X800-Q3400 scale-out network, an SN6800 scale-out network could consist of two switch planes though the SN6800 enables a much larger feasible scale-out world size.

Evidence

For a 512-port switch, we can connect up to 131,072 GPUs with two layers of switches or a ludicrous 33,554,432 GPUs on 3 layers.

Context After

(2\left(\frac{512}{2}\right)^2 = 131,072)

② Atomic Claim

對 512-port switch 而言，2-layer switches 最多可連接 131,072 顆 GPUs；3 layers 則可達 33,554,432 GPUs。
