Nexus series Fabric module 1 & 2 coexisting

[mhiyoshi]

I think there are Fabric module to enhance backplane bandwidth and performance.

However basically there are 2 types of fabric module, so I would like to know whether

these types are possible to coexist or not.

They "can" co-exist, however, if you want to do this long term, i.  e.  more than 2 hours, then you may as well take your FAB-2 and throw it away.  Let me explain:

The decision to allow FAB-1 and FAB-2 to work together in a single Nexus 7K chassis is purely for "hitless" or non-disruptive upgrade from FAB-1 to FAB-2 card.  When you install the first FAB-2 card into a chassis with FAB-1 card, the FAB-2 card will downgrade it's speed to match the FAB-1 card's speed.  Once you remove the last FAB-1 card will the entire Nexus 7K chassis' backplane speed go up to the speed of the FAB-2.

Does this make sense to you?

Thank you for your precious information. Yes it makes sense very much.
