Whoooops!
When I did the IP-layout for about two-three weeks ago, I assumed a /20-prefix for the out-of-band management (or lights-out management, LOM for short — in our case CHARM and BMC) for the two /21-prefixes I made for the PROD- and DEV-cluster. However, since nodes outside these subnets also have CHARM/BMC-cards, and in order to have some consistency, I had to find another solution. I gave it some thought, and ended up with the following setup;
10.162.0.0/21 # PROD (ethernet) 10.162.8.0/21 # DEV (ethernet) 10.162.16.0/21 # PROD (infiniband) 10.162.24.0/21 # DEV (infiniband) 10.162.32.0/21 # Free 10.162.40.0/21 # Free 10.162.48.0/22 # Infrastructure 10.162.52.0/22 # VMs 10.162.56.0/24 # Gateway 10.162.57.0/24 # LOGIN-PROD 10.162.58.0/24 # LOGIN-DEV 10.162.59.0/24 # Admin 10.162.60.0/24 # SWITCH-MGMT 10.162.61.0/24 # Not-authorized hosts 10.162.62.0/23 # Free 10.162.64.0/18 # Free 10.162.128/17 # MGMT |
