Nexus 7000 Switch Fabric Redundancy with Fab-2 ?

[dumlutimuralp]

Hi all,

I know that N7K did not have N+1 Switch Fabric redundancy. It is required to have all five SF modules to provide full throughput. Does this change with FAB-2 modules ? I mean with new modules, does N7K have N+1 SF redundancy ?

Thanks in advance.

The N+1 fabric redundancy will depend on the type of module.

If you are using M132 (80G) per slot and you have 3x FAB-1 (46G each), it will provide N+1.

The same story applies to FAB-2. If you are using the F1 series, and have 4x FAB-2, you have N+1. Of course, if you are using F2 series linecard and have all FAB-2 populated, you don't have N+1 because F2 is 480G and all 5 FAB-2 will give you 550G.

HTH,

Thank you. I thought Fab-2 modules provides 220G per slot but noticed that it gives 110 Gbps per slot.

cheers.
