We have two Nexus 5020's that will be deployed in a data center with several FEX . I haven't decided yet whether to single or dual home the FEX's or if I'm going to use vPC's right away.
Are there things I should consider when numbering the FEX's ? If I don't use vPC's then I could duplicate FEX numbers across both 5020's, but is that going to cause problems later if I use vPC's ? Do most people keep the FEX numbers unique between 5020's ? (ex. odd on one and even on the other).
Any thoughts on the subject would be appreciated.
