Data Director components communicate by using vSphere networking resources. Before you start planning your network, you must understand vSphere and Data Director networking.

Data Director requires networks to carry communications among its components, including the following.

Communication between the Data Director Management Server and database servers.

Communication between database servers and applications.

Communication between the Data Director DB Name Server and applications.

vSphere administrators create switches and networks for each ESXi host. As a vSphere administrator, you can either designate existing networks for Data Director use, or create and configure networks for Data Director use. These networks will be used for the Management Server and for one or more DB Access Networks.

You specify the different networks at different times in the installation and setup process.

vCenter Network and Web Console Network

You specify the vSphere port groups (networks) to use for vCenter Network and Web Console Network during Data Director vApp deployment.

Note

Set up vSphere Update Manager to use the vCenter Network to communicate with Data Director. If vSphere Update Manager uses a different network, it cannot function properly.

Internal Network and DB Name Service Network

You set up the Internal Network and DB Name Service Network after the Data Director vApp deploys, during the Data Director setup process. See Configure Network Mapping. DHCP or IP pool must be enabled on these networks.

DB Access Network

A DB Access Network is the interface to the database virtual machines (DBVMs) and carries SQL traffic. DBVMs run the actual databases and are created when users create databases. DHCP or IP pool must be enabled on DB Access networks. You can configure as many DB Access networks as there are databases. You select the vSphere networks to use for the DB Access Network when you create resource bundles. See the vFabric Data Director Administrator and User Guide.

Best practice is to set up your Data Director networks as separate subnets, such as using different VLANs, to provide the best security. Use VLANs with 1-Gigabit or higher speed Ethernet interfaces.

In addition to network setup, you must also open certain ports in your firewall. See Data Director Networks, IP Allocation, and Firewalls.
