You complete the setup of the Foundation appliance by configuring the Cloud Management Network on the Cloud Networking pane of the Settings screen. When the settings are saved, the Foundation appliance automatically creates the Software Defined Network (SDN) controller and three network node appliances. Using three network nodes provides increased reliability and scalability. Each of these appliances runs in its own virtual machine.
The Cloud Networking settings control the configuration of the private network that connects the CloudSystem Foundation base appliance to compute nodes and virtual appliances. See CloudSystem appliances and network infrastructure.
After you configure Cloud Networking, the SDN controller runs in the background to manage CloudSystem Console network connections. The base appliance provides a DHCP service on the Cloud Management Network, and the network node appliances provide DHCP IP addresses for virtual machine deployment. The network nodes use only the Cloud Management Network you specify. They do not have public IP addresses.

NOTE: Verify that the management hypervisor can support the additional appliances that are created during cloud network setup. |

Cloud networking can be edited when there are no activated compute nodes. After compute nodes are activated, changing the cloud networking configuration requires resetting your environment.
If you must change the cloud networking configuration after compute nodes are activated, first perform the following tasks to reset your environment.
-
Delete virtual machine instances. See Delete instance.
-
Deactivate compute nodes. See Deactivate a compute node.
-
Then, edit the Cloud Management Network. See Edit Cloud Networking.
