Configure a New Directory Backbone

When you open DXmanager for the first time, you can run a wizard to help you create a simple backbone.

The DXmanager wizards include some default values. We recommend that you use these default values unless you are sure that your backbone requires a different value.

To configure a new directory backbone

1. Log in to DXmanager as a user with the Change or Superuser role. These roles give you permission to change the directory backbone's configuration.

   DXmanager opens, showing a page that links to the following items:

   • Single DSA Backbone

     Opens a wizard that helps you enter the information required to create a simple backbone with one host that contains a single DSA.

   • Advanced

     Opens DXmanager in Edit mode, so you can create the configuration without the wizard.

2. Click the Single DSA Backbone link.
3. In the first page, define default values for the whole backbone.
4. In the second page, define namespace partitions.
5. Define the network topology in the following order:
   1. Define the regions.

      Most directory backbones require only a single region. You should define more than one region only if areas of your network have high latency, slow links, or low bandwidth.

   2. Define the sites.

      A site is a collection of hosts, over which router DSAs can share the load of requests. Each site defined in DXmanager is likely to correspond to an actual data center.

   3. Define the hosts.
6. Click Configuration, Deploy to update the hosts with the new configuration.
