The N9K-C9332D-GX2B is the 1U 32x 400GbE model that is similar to the Inside an Innovium Teralynx 7-based 32x 400GbE Switch we looked at prior to Innovuim being purchased by Marvell. You can see inside that 32x 400GbE switch here:

This level of networking is becoming harder to fit in a 1U or 2U chassis just due to the power consumption requirements. Eventually, we will see these switches need to swap to co-packaged optics. As we have gone over previously, there are a lot of operational challenges with co-packaged optics so companies like Cisco have innovated to push the boundaries to switch a few more generations.
