I believe it can be broken down to 200GbE and 100GbE though. It is too bad that it can't route to the management ports for a 10GbE outgoing connection (or maybe it can and I wasn't paying enough attention).

I can see a few uses for this: 1) cluster 4x GB10 machines 2) Connect a small group of video editors via 100GbE to a NVMe file server. 3) Overkill home office network, just because.
