Agreed. Higher end network gear is $$$. :(
EPYC servers (128 PCIe lanes) would probably be the go too, not Xeons.
This is just Imagineering though. ;)
With the specifics, wouldn't it be 4 cards needed? Each card has 2x 100Gb/s ports, so 8 ports in total.

You would need 4x 200Gbps ports to reach 100GB/s, so 2x MCX653105A-ECAT (each 2x 16-lanes) at > $700 each, and pay for 1/10th of a ~$30 000 switch, IOW 100GB/s would cost you ~ $4400, before paying for the storage.
Sure, it could be done, but it wouldn't be cheap, and you'll have used most of the PCIe lanes.
