You are only citing Intel PR material. No word about vendor locking of DAC cables or QSFP28 modules. Are there any locks? X520 could be persuaded with an EEPROM patch[1]. No word how fast the card can ping-pong data at small (64) and large (1500) packet sizes between say two EPYCs or two recent Xeons. How about benchmarks when serving data from Optane with Samba or NFS or iSCSI from a share? What is the CPU load for RoCEv2 vs. none? No word how stable the software stack is in Linux and Windows right now. Any hangs that put the entire link offline for 1-5 seconds, while the driver re-inits the chip[2]? Seen that with X710 alot, until finally an NVM update turned off enough of the offloading-features. How about embarassing interop issues as in their I225-V at 2.5 GBps[3]? No word about the competition in terms of pricing?

With that kind of a track record, I'll take two for $100. $50 if we find out the card produces latency spikes >100µs, $1 if its so bad that people notice the packet loss when calling over VOIP.

Look at the development history of 810s...overall seems similar to i40e, firmware and offload problems (allegedly )

Does this card support 40GE? I have not upgraded to 100GE switches yet but I would prefer to have this cards features on 40GE and then just upgrade to 100GE switches.
