Hi Emanuel,
I'm in the process of building a similar workstation for work with an
X440. I don't have any firm recommendations, but I am interested to
hear from others on the forum. My understanding is that with full-rate
streaming, existing workstations are not going to be able to do much
more than write samples to storage. If you need any processing applied
to those samples, you probably need to build a custom RFNoC block for
the FPGA.
I'm also targeting the Threadripper series hosted on a Asus Pro WS
WRX90E-SAGE SE. As for SSDs, I'm planning to use mdadm to apply RAID 0
to four gen 5 NVMe drives.
Thanks,
Ryan
It has been the case for quite some time that high-end SDR hardware
outstrips the ability of Moore's law to "keep up" on the
conventional-CPU end of things.
Carefully-constructed use of GPUs can help, but GPUs have this
unpleasant latency problem in "set up" of the computations that means
you can't usefully use them
in the *middle* of a DSP flow. At least that's the way it was a
couple of years ago when I looked into this.
Another approach might be to construct multiple flows, each comfortably
"sub Moore's-law", and using the "alternate stream destination" facility
stream sub-bands to
different computers. This approach works for some types of
problems, but not others.

Hi everybody,
we foresee a X440 for our research and are looking for hints on
suitable PC hardware/architectures for high-rate streaming and
storage of I/Q samples, as well as online-processing.
100Gbit-NICs can be found in the knowledge base, yet I would be
more be interested in suitable CPUs etc.
Given the high bandwidth we have a Ryzen Threadripper based system
in mind.
Does anyone have experience with Xeon oder Epyc based systems in
this regards?
Do you have recommendations for suitable SSDs for raw data storage
(not necessarily consumer grade, can also be SSDs built for servers)?
Any insight is highly appreciated.
Kind regards,
Emanuel
