I’ll create three physical and two virtual networks:
1. physical: DMZ
This is the seperate network space I’ve created in which I can place my test hosts/environments, in this case the Binsfeldius Cluster. This address space is behind a firewall and has Internet connectivity, hence the cloud. Each cluster node will receive an address from this range. The virtual Microsoft TMG and the DC1 (see the chicken or the egg post) are the only VM’s who have a connection to this physical network. The cabling is blue.
172.16.111.x /26 (62 hosts – subnet 192)
2. physical: TTG Storage Network (the 12-network)
I’ve separated the storage network and it runs on a seperate Netgear ProSafe switch. Each cluster node will receive an address in this range to be able to boot from NAS, and to provide access to the Cluster Shared Volume. The cabling is yellow.
172.16.12.x /28 (14 hosts – subnet 240)
3. physical: TTG Heartbeat / Live Migration Network (the 13-network)
This network connects its cluster node to yet another separate Netgear ProSafe switch to enable Live Migration between the nodes and to provide the cluster heartbeat. The cabling is green.
172.16.13.x /28 (14 hosts – subnet 240)
4. virtual: TTG LAN (the 11-network or TTG DMZ VLAN #601)
This is a virtual switch which is the primary connection for each VM. It is a routed network which has it’s gateway set to the virtual Microsoft TMG (link) so every VM connection has to go through the TMG for normal operations.
It might seem odd as normally you would not place the firewall on the cluster but around the nodes as well. In my case A) I don’t want to have any additional physical machines other than the cluster nodes and B) the TMG is part of the products to be tested in-line with the VM’s. The virtual switch is connected on the DMZ physical NIC using VLAN ID #601 due to the virtualized TMG and having only three physical NICs per node. The virtual switch needs to connect between nodes via a physical connection.
172.16.11.x /26 (62 hosts – subnet 192)
5. virtual: TTG DMZ
This virtual switch is the bridge between Microsoft TMG and the physical switch:DMZ.
