After you create the VMware Cloud Director server group, you can install a Cassandra database. If you are using a PostgreSQL database, you can configure SSL and adjust some parameters on the database.

After the creation of the VMware Cloud Director appliance, you can use the vSphere networking features to add a new network interface card (NIC). See the Add a Network Adapter to a Virtual Machine information in the vSphere Virtual Machine Administration guide.

Note: If your cluster is configured for automatic failover, after you deploy one or more additional cells, you must use the Appliance API to reset the cluster failover mode to Automatic. See the VMware Cloud Director Appliance API. The default failover mode for new cells is Manual. If the failover mode is inconsistent across the nodes of the cluster, the cluster failover mode is Indeterminate. The Indeterminate mode can lead to inconsistent cluster states between the nodes and nodes following an old primary cell. To view the cluster failover mode, see View Your VMware Cloud Director Appliance Cluster Health and Failover Mode.

Service providers and tenants can use the VMware Cloud Director API to test connections to remote servers, and to verify the server identity as part of an SSL handshake. To protect VMware Cloud Director network connections, configure a deny list of internal hosts that are unreachable to tenants who are using the VMware Cloud Director API for connection testing. Configure the deny list after the VMware Cloud Director installation or upgrade and before granting tenants access to VMware Cloud Director. See Configure a Test Connection Denylist.
