From the Mirantis Planning Guide - Connecting the dots



The setup guide does not go into exact details of setting up switch to match each possible configuration, but it does give some diagrams.  The two that match up to my setup are above.  I am attempting a 2 nic setup for my compute node and controller nodes.  From what i can see, this translates into 2 VLANs plus the original default VLAN on my switch that has internet connectivity.

So for the VLAN configuration in Cisco Network Manager, i am going to configure this.


I have two NICs on each of my machine and 3 nics on the Controller (other docs had shown setup with more NICS on controller - I will use to connect to internet if needed i guess).  This is the nature of the Mirantis documentation - they cannot possibly cover all configurations so it looks like you have interpolate for you setup.

Fuel Master: 2 NICS
Compute: 2 NICS (4 NICS installed)
Controller: 2 NICS (3 NICS installed)
Storage: 2 NICS 
Extra Node: 2 NICS

Will do all the wiring and fire up Fuel.  Fuel defaults to having network configured as 10.x.x.x.  Have to figure out how to setup the "Admin" VLAN to make sure it doesn't use DHCP... As for the other VLAN (br-eth1) - I am hoping that it will resolve addresses (DHCP) by some magic that Fuel does with tagging under the covers.  I am just using the switch to isolate the traffic.
