Heya, I do very much the same QSFP28-EDR 100G adapter cards into QSFP+-FDR 56G just with the use of a cable. I even QSFP+-FDR to 4x SFP+-10G using various brocade, mellanox, chelsio hardware and have never come out worse.
Some cables can be a bit funny but I have never had issues with cables branded by NetApp, DELL, CISCO or purchasing coded variants from suppliers. However FS.com are a valued cable supplier for anything that I might think could be a bit fickle. Allot of the time it is cable compatibility and rarely the adapters themselves. Hope this help you out buddy :) Kind regards, Darren Wise https://wisecorp.co.uk https://kotidc.com https://thirah.com https://woprcompute.com https://adsstech.com On 1 March 2021 19:02:36 GMT, Michael Di Domenico <mdidomeni...@gmail.com> wrote: >has anyone plugged a mellanox fdr card into a mellanox edr switch? i >need to connect a server that doesn't have a x16 port so no edr card, >but i do have an fdr card that's x8. i don't need the speed just the >connection, but i've not tried this before. a quick google says it >should work, but i'm loathe to until i hear someone else has. >_______________________________________________ >Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin >Computing >To change your subscription (digest mode or unsubscribe) visit >https://beowulf.org/cgi-bin/mailman/listinfo/beowulf
