The Geographic Redundancy feature of System Manager consists of two System Manager servers located in geographically remote locations. This feature ensures that the management of enterprise communications remains unaffected during the failure of a single System Manager server or during network failures.
The Geographic Redundancy feature provides the following replication mechanisms to ensure data synchronization between the primary and secondary System Manager servers:
  • Database replication
  • File replication
In a system consisting of geographic redundant System Manager servers, the main components include two System Manager servers located in geographically diverse locations. One System Manager server is designated as the primary System Manager server. On a sunny day, the primary System Manager server manages all elements in the system. The other System Manager server, designated as the secondary System Manager server, remains in the standby mode. You can administer the secondary server in the active mode if the primary System Manager server fails or loses connectivity with the Avaya Breeze® platform servers.
The network with geographic redundancy operates in the following scenarios:

Sunny day scenario

In this case, the primary System Manager server manages all Avaya Breeze® platform servers and replicates administration changes to all Avaya Breeze® platform servers. The secondary server is in the standby mode, and you cannot make any administration changes by using the secondary server.

Rainy day scenario

In this case, the secondary System Manager server manages all Avaya Breeze® platform servers and replicates the administration changes to all Avaya Breeze® platform servers. The primary System Manager server has failed or has lost connectivity with the Avaya Breeze® platform servers. The primary server is offline, and you cannot make any administration changes by using the primary server.

Split-network scenario

In this case, you can administer the secondary System Manager server to the active mode when the primary System Manager server is also in the active mode. When connectivity failure occurs in the network, some Avaya Breeze® platform servers can communicate only with the primary server. Other Avaya Breeze® platform servers can communicate only with the secondary server. However, some servers can communicate with both.
