Replication Zones
Replication Zones allow you to associate specific Exchange servers with a
preferred series of VaultBoxes within your environment. For smaller
environments, there may only be a single Replication Zone and all Exchange
servers are members of this zone. Administrators of larger environments can
create multiple zones to segment and load balance replication traffic to specific
VaultBoxes. After Replication Zones have been created and all servers have been
assigned to a zone, a corresponding DNS Forward Lookup Zone should be
created in the environment for each Replication Zone defined within ESS. Within
that Forward Lookup Zone, MX records should be created using the fully qualified
domain name of the VaultBoxes using appropriate weighting of records to create
the preferred routing topology.
NOTE Replication Zones Apply to Servers, not to Users
Replication Zone routing corresponds to the server that bifurcates the message
(typically the first Exchange Server to touch a message), not the server on
which a particular user resides.
To assign servers to replication zones:
1 From the Administration Console, select Historical Mail.
2 Click Replication Zones. The Zones page displays, containing a list of
Exchange Servers.
3 Click Add new zone….
4 In the text box that displays:
a. Enter the name of the zone you want to add and click Submit. The
newly added zone displays above the Add new zone... button.
b. In the bottom section of the Zones page, for each server you want
added to the new zone, click the appropriate Add to zone... link.
5 Repeat for each zone, as needed.
