Hello, I am trying to get the full sampling rate from the USRP x410
which is 400 MHz. I understand that I will need a 100 gigabit
ethernet connection to do this. Do you have any setup recommendations
or rack mounted server recommendation that can support this bandwidth?
Thanks,

That's a question with no hard answer.
Whenever this class of question comes up, I have to ask "what do you
want to DO with those samples?". If you want to just
record them, then, you also have to consider the recording
mechanism. 400e6 x 4 bytes == 1.6Gbyte/second recording
capacity.
If you want to do "computey things" at those rates, then you have to ask
"can those computey things be easily decomposed
such that they can be shared across multiple cores?" "what are the
memory-bandwidth requirements of what I want to do?".
Basically, what I'm saying is that there is no tidy answer without
knowing the "shape" of what it is you want to do...
