Trying to wrap my head around the Nexus Data Centre solution compared to other vendors. Anyone make any comparison with other vendors. Anyways, FEX cons below and wonder if it is true or am I misunderstand the CCO doc.
1. FEX does not support local switching which seems inferior
2. Pinning seems weird concept:
so assume all 4 x 10Gig is used and per above link:
âWhen the Fabric Extender is brought up, its host interfaces are distributed equally among the available fabric interfaces. As a result, the bandwidth that is dedicated to each end host towards the parent switch is never changed by the switch but instead is always specified by youâ
Note If a fabric interface fails, all its associated host interfaces are brought down and remain down until the fabric interface is restored.
Say 4/48 = 12 so for sake of argument, I assume
hostport 1-12 = Fabric/F1
hostport 13-24 = Fabric/F2 etc..
If Fabric/F1 dies, does all ports 1-12 die with it or does it get route over to F2, F3, and F4?
