An element is an instance of an Avaya Aura® network entity. System Manager manages elements such as a Session Manager server or a Avaya Breeze® platform server in an Avaya Aura® network.

The first or the master System Manager server in a Geographic Redundancy set up that serves all the requests. The primary System Manager server is always in the active mode unless you turn off the server. In fail back cases, the primary System Manager instance might not be in the active mode.

The System Manager server that functions as a backup to the primary System Manager server. The normal mode of operation of the secondary System Manager server is the standby mode.

The mode of operation of the System Manager server where the server provides the full System Manager functionality.

The mode of operation of the System Manager server where the server serves only authentication and authorization requests. In the standby mode of operation, the system supports limited Geographic Redundancy configuration and the inventory service.

Those elements of the Avaya Aura® solution that support the Geographic Redundancy feature, such as Avaya Breeze® platform Release 3.0.

Those elements of the Avaya Aura® solution that do not support the Geographic Redundancy feature, such as Avaya Breeze® platform instances earlier than Release 3.0.

The Geographic Redundancy feature provides the following replication mechanisms to ensure consistency of data between the primary and the secondary System Manager servers: database replication, file replication, and LDAP replication. For more information, see Administering Avaya Aura System Manager.
