    Hi,

    Just bought an Arista DCS-7050Q-16 switch on ebay and wanted to know if anyone has one of this working with Brocade 10GbE SFP+ transceivers (PN: 57-0000075-01)?
    Also can anyone recomend 1M long compatible QSFP+ cables to work with Mellanox MCX354A-FCBT cards?

    Every transceiver should work after running "touch /mnt/flash/enable3px" in bash.

    For the fdr cards I would try to get fdr14 cable (there were a bunch of ibm branded mellanox cables "cheap" on ebay, ~$20 for 1m, $30 3m) in case that you want to try fdr infiniband or 56gbe on a mellanox switch :D.

    The command i386 mentioned will work in EOS 4.14 and earlier.

    This switch will run EOS 4.18 without a problem, but that's as far as it goes.

    If you want a newer version of EOS you can pick up optics at FS.com reasonably cheap. Arista supports any DAC regardless of EOS version. Our switches are in the same rack as the servers so we just use DAC's, some Arista, some Cisco, no issues with Cisco, or Mellanox cards.

    Thanks for the information. I will post my findings when I receive the switch :)

    Haven't used Brocade but ordered some QSFP+ DAC cables from FS.COM to connect all our switches (Cisco Nexus 9000 N9K-M6PQ-E). We had no hassle in terms of achieving speed and performance for the Mellanox and Net-gear/CISCO 40G Ethernet switches etc.

    We already covered this in a previous thread, there exists a command ("service unsupported-transceiver") to allow unsupported transceivers. It requires a specific input but its not bound to any serial or hardware, just the nonce and code, which should be able to be found with a simple search.
