One VLAN mapped to the DB Name Service Network enables database client applications to connect to
DBVMs. The clients request the database virtual machine IP address from the DB Name Server using the
DB Name Service network. The DB Name Server provides connection information to a database client
application, which then connects to the database using its Database Access Network. Any database client
that will issue SQL traffic to a database managed by Data Director must have access to this network using
port 389.
In addition, DB Access Networks carry SQL traffic between database client applications and the vPostgres
databases. These networks are not defined at installation. DB Access Networks are made available when Data
Director system administrators define resource bundles in the Data Director UI and assign the resource bundles
to organizations. A DHCP Server is required on the DB Access Networks. Set aside at least one network for
the DB Access Network.
Minimum Two VLAN Network Configuration
A minimum network configuration includes one network to carry Internal Network traffic, and one network
for all other traffic. This setup requires two networks with 1-Gigabit or greater Ethernet interfaces.
NOTE Avoid single-network configurations. Because of security considerations, place the Internal Network
on its own isolated vSphere network.
The following diagram illustrates a two-VLAN network configuration.
