Replica View for a Partition
You might create such a partition because the directory has so many objects that the server is
overwhelmed and access to eDirectory is slow. Creating the new partition allows you to split the
database and pass the objects in that branch to a different server.
The example above shows the Replica View for the Finance partition.When you display the Replica
View for a partition in iManager, any servers holding a replica of that partition are shown on the
right. In this case, Server1 holds a Read-Write replica of the Finance partition. For more
information, see
“Viewing a Partition’s Replicas” on page 143 .
1.5.2 Distributing Replicas for Performance
In the preceding example, suppose that Server1 holds replicas of both the Tree partition and the
Finance partition. At this point, you haven’t gained any performance advantage from eDirectory
because Server1 still holds the entire directory (replicas of both partitions).
To gain the desired performance advantage, you need to move one of the replicas to a different
server. For instance, if you move the Tree partition to Server2, then Server2 holds all objects in the
Tree and YourCo containers. Server1 holds only objects in the Finance and Accounts containers.
The load on both Server1 and Server2 is less than it would be with no partitioning.
1.5.3 Partitions and WAN Links
Suppose your network spans two sites, a North site and a South Site, separated by a WAN link.
Three servers are at each site.

Sample eDirectory Containers
eDirectory performs faster and more reliably in this scenario if the directory is divided in two
partitions.
