Administrator Guide 6 - 3
Adding data centers to the globally-distributed network
configuration
The first task you perform is to add your data centers to the 3-DNS
configuration.
To add data centers using the Configuration utility
1. In the navigation pane, click Data Centers .
The Data Centers screen opens.
2. Click Add Data Center on the toolbar.
The Add Data Centers screen opens.
3. Add your data center information. For information and help on the
specific settings on this screen, click Help on the toolbar.
4. Repeat the previous steps to add all of your data centers to the
configuration.
Configuration notes
For the globally-distributed network configuration shown in
Figure 6.1, on page 6-1, we have added two data centers labeled
West Coast - DC and Europe - DC .
Adding 3-DNS Controllers to the globally-distributed network
configuration
Once you have added all of your data centers to the 3-DNS configuration,
you are ready to notify the 3-DNS Controller that you are configuring about
the 3-DNS Controllers in your network, including the 3-DNS Controller you
are configuring.
Note
Please note that when you are working with more than one 3-DNS
Controller, you create your entire configuration on one system and then add
the second system using the
3dns_add script. The 3dns_add script copies
the entire configuration from the first (or existing) system onto the second
(new) system, and synchronizes all of the settings. For details on
configuring additional 3-DNS Controllers in existing networks, using the
3dns_add script, see Chapter 10, Adding a 3-DNS Controller to an
Existing Network .
To add 3-DNS Controllers using the Configuration utility
1. In the navigation pane, expand the Servers item, then click 3-DNS .
The 3-DNS List screen opens.
