Hello, Brandon Martin<lists.nanog@monmotha.net> , 31/3/2015 10:07 PM: I'm not sure where the VDX line ends up in this. It's apparently somewhat the result of actually merging the two technology lines, and it runs somewhat different software as a result. The VDX was AFAIK already in development before Brocade bought Foundry, which is further backed up by the fact that in e.g. FlexOptix's transceiver re-programming tool you have to select a "Brocade Storage" firmware for those transceivers rather than the "Brocade IP" firmware used for Foundry-like gear. It is however true that Brocade has since ported over a lot of Foundry features to the VDX platform. As for optics: it will work well (read: interface comes up and passes traffic) with most other-vendor transceivers even if you don't re-program, but like the Foundry-lineage kit you lose light level monitoring when the firmware doesn't match.
