Hi, I am in the process of purchasing a 100Gb NIC for use with the X410 and have seen documentation and previous posts indicating that the ConnectX NICs are preferred. But I did note in the DPDK knowledge base article that the Intel E810 could also work. I prefer the E810 because it seems to be less expensive and can be configured for 4x10Gb, but I don't want to create a headache for myself. Let me know if you have had success or issues with the E810 using a 100Gb link (or two 100Gb links) to the X410.
I am also confused about the E810 which comes in a couple of 100Gb models: CQDA2 and 2CQDA2, where they both have two 100Gb QSFP28 ports, but the former can only handle aggregate 100Gb whereas the latter can handle aggregate 200Gb. My confusion is "why does it matter for the X410?". With 4 channels at 500 MS/s, the aggregate bit rate is only 64Gb/s so why does it matter if the E810 CQDA2 only supports aggregate 100Gb? It seems to me that either model supports the maximum rate of the X410. Thanks. Rob
