In some network environments it is neccessary to have multiple Messaging Gateway (SMG) Control Centers to manage scanners in different data centers. Depending on the administration or mail policy needs, it may be helpful to have a primary / central Control Center which can provide shared policies with the Control Centers which are used to manage SMG scanners in disparate data centers.
Setting up a Messaging Gateway Control Center cluster takes multiple steps:
At this point the Control Center is set up to act as the primary / central Control Center in a cluster and a Global tab will have been added to the Content > Policies page for use in creating global content policies.
To add a secondary / remote control center to SMG Control Center policy sharing a trust relationship will need to be set up between the Control Centers and some certificate information shared between them.
At this point the two Control Centers are connected and Global policies can be created and shared from the Primary / Central Control Center Content > Policies > Global page.
