    Hi there
    how easy is it to add 5 more switches to an existing stack of 4?

    Right now my configuration is


    vsf secondary-member 2
    vsf member 1
    type jl661a
    link 1 1/1/49
    link 2 1/1/50
    vsf member 2
    type jl661a
    link 1 2/1/49
    link 2 2/1/50
    vsf member 3
    type jl661a
    link 1 3/1/49
    link 2 3/1/50
    vsf member 4
    type jl661a
    link 1 4/1/49
    link 2 4/1/50

    do I just continue on with

    vsf member 5
    type jl661a

    link 1 5/1/49

    link 2 5/1/50

    and so on?

    6300F an 6300M support both VSF stacking but cannot be combined in one VSF stack, be sure all models are 6300F or 6300M.

    Your setup is basicly ok! You can also set some priority to the members.
    Theoretical you can put 8x 6200F switches or 10x 6300F switches in a VSF stack (you can’t combine both models)

    See also the Aruba-CX VSF User Guide: https://www.arubanetworks.com/techdocs/AOS-CX/10.07/PDF/5200-7889.pdf

    Design recommendation is to keep a VSF stack on max. 4 or 5 nodes (personal opinion)

    Maybe you can create a stack of 4nodes and another stack of 5nodes and give each stack a 2x10gb uplink to your coreswitch?
    Also calculate overbooking of your uplinks, on your edge this is someware between 10:1 and 20:1 depends on your use case.

    4x48G=192Gbps edgeinterface / (2x10Gbps uplinks)= 10:1 = perfect in most cases
    9x48G=432Gbps edgeinterfaces / (2x10Gbps uplinks)= 21:1 = pretty high overbooking in most cases
     
    Of course you can add 1 uplink to each node but known how your traffic flows in VSF.
