Traffic on Each VLAN
The two VLANs carry the following traffic.
n
One VLAN is for the shared network for vCenter, Web Console, DB Name Service, and DB Access
Networks.
n
One VLAN is for the Internal Network. This VLAN carries internal management traffic between databases,
the Data Director Management Server, and the DB Name Server. The Internal Network must be a VLAN.
Required IP Addresses and Setup
This configuration requires DHCP or IP pool on the shared (vCenter Server, Web Console, and Internal)
network, and for the DB Access network. To handle internal management traffic, the DHCP range or the IP
pool should have at least as many IP addresses as the number of databases. See “Data Director Networks, IP
Allocation, and Firewalls,” on page 15.
Limitations
Because all vCenter Network traffic, Web Console Network traffic, and SQL traffic is carried by one network,
you cannot isolate databases into different networks.
One VLAN Network Configuration
A one VLAN network configuration includes only one network. Due to performance and security
considerations, this configuration is not suitable for production.
The following diagram illustrates a one VLAN network configuration.
