Hello, Has anybody tried to use QSFP28 network adapter from intel with USRP X410 and not Mellanox/Nvidia that is sold by NI for use with X410? Intel cards have some advantages over Mellanox. One of them is configurability of the QSFP28 port to act as four SFP+ or SFP28 ports. But I didn’t see any reports how these cards behave together with X410. Therefore if anybody tried to use intel card + X410, I would be grateful to hear how this combination worked. Best Regards,\ Piotr Krysik

Hello, Answering my own question: these brochures are closest to answering what I need to know: https://kb.ettus.com/images/f/f8/Open_Architecture_For_Radar_and_EW_Research_v1.0.pdf www.ni.com/content/dam/web/pdfs/oarer_solution_brochure.pdf They lists Intel E810-CQDA2 network adapter as a one that was validated with USRPs. Although not in 2xQSFP28 mode but acting (probably) as 8xSFP+ 10Gbit/s interfaces. The card also seems to have quite good support from DPDK: https://fast.dpdk.org/doc/perf/DPDK_21_08_Intel_NIC_performance_report.pdf Does anybody have experience with E810-CQDA2 + USRP X410? Best Regards,\ Piotr Krysik

Hi Piotr, I don't know of anyone who has tried that card specifically for 10 GbE, but Intel cards in general are commonly used with USRPs for 10 GbE. However, the Intel cards are not recommended for 100 GbE on X410. See here for the recommended cards and cables which has been tested and validated for 100 GbE: https://kb.ettus.com/X410#100_Gigabit_Ethernet There was a post on the mailing list a while ago from someone who tried to use a similar card with 100 GbE and ran into problems: https://lists.ettus.com/empathy/thread/IA2YCIJTQOEPNJOPF3AJUXC3I6ONRCJR Wade On Tue, Feb 21, 2023 at 5:23 AM <perper@o2.pl> wrote: > Hello, > > Answering my own question: these brochures are closest to answering what I > need to know: > > > https://kb.ettus.com/images/f/f8/Open_Architecture_For_Radar_and_EW_Research_v1.0.pdf > > www.ni.com/content/dam/web/pdfs/oarer_solution_brochure.pdf > > They lists Intel E810-CQDA2 network adapter as a one that was validated > with USRPs.
