HP-UX Directory Server 8.1 deployment guide

The master copy of the data for dc=example, dc=com and the root entry, dc=com, is stored
in the l=Europe database.
The data center in Europe contains the master copies of the data for the extranet. The extranet
data is stored in three databases, one for each of the main branches. The master copy of the data
for o=suppliers is stored in database one (DB1), that for o=partners is stored in database
two (DB2), and that for ou=groups is stored in database three (DB3).
The database topology for the extranet is illustrated below:

means it has three data centers, each containing two supplier servers, two hub servers, and three
consumer servers.
The following diagram illustrates the architecture of Example Corp. Europe's data center:
