       Start small
                                       Fiber link to distribution switch
                                         Switch
                                         Switch
                                         Hosts

     Build Incrementally
       As you have demand and money, grow like 
         this:
                                        Aggreg.
                                        Aggreg.
                    Switch
                    Switch
                                         Hosts
                                                                                            4
     Build Incrementally
       And keep growing within the same 
         hierarchy:
                                        Aggreg.
                                        Aggreg.
                    Switch                                       Switch
                    Switch                                       Switch

                                                                                            5

       At this point, you can also add a 
         redundant aggregation switch:
                            Aggreg.                 Aggreg.
                            Aggreg.                 Aggreg.
                    Switch                                       Switch
                    Switch                                       Switch
                                          Hosts
                                                                                            6
