In Superpod networking, if I configure 4 NDR200 cards on each server, can I directly connect to the same switch with a 1-to-4 cable? Or do I have to use two 1-to-2 cables to connect to different switches?

Not recommended. This connection mode does not comply with SuperPoD networking rules. Considering the NCCL/SHARP performance, Leaf switches need to connect NDR200 ports of different servers in the SU with one-quarter cables to form different communication rings.
