5.2.1. About Using Multiple Databases

Directory Server stores data in LDBM databases. This a high-performance, disk-based database.
Each database consists of a set of large files that contain all of the data assigned to it.
Different portions of the directory tree can be stored in different databases.
Figure 5.1, "Storing Suffix Data in Separate Databases"
For example,
stored in three separate databases.
Figure 5.1. Storing Suffix Data in Separate Databases
When the directory tree is divided between a number of databases, these databases can then be
distributed across multiple servers. For example, if there are three databases, DB1, DB2, and DB3, to
contain the three suffixes of the directory tree, they can be stored on two servers, Server A and Server
B.
