Licensed Customer Confidential Planning RedirectorSink/RedirectorController Placement

Email Continuity Administrator Guide version 6.5 (1st ed.) 37

As part of your installation, Support helps you install a single RedirectorController

in your environment. You can install additional controllers by running setup and

choosing the secondary controller option.

When planning for secondary controllers, consider the following:

Geographic diversity—If Exchange servers are available in multiple locations,

placing controllers in multiple locations helps protect against catastrophic failure

or power outage in a single location.

Figure 2-5 RedirectorControllers in Multiple Locations

WAN topology—Where loss of wide-area network (WAN) links, firewalls, or dial-

on-demand links may isolate servers from available controllers, strategic

placement of secondary controllers allows RedirectorSinks to obtain updated

routing information.
