Topology-split architecture shows the Topology Split Manager architecture for a deployment that has <n> domains named AM001, . . ., and AM00<n>.

Figure 1. Topology-split architecture

The Topology Split Manager splits the topology into <n> domains, which reduces the scope of topology that is managed by each IP Availability Manager while minimizing the overlap of the discovered devices within the domains and ensuring that no coverage gaps exist across the domains.

Through the optional VMware Smart Assurance Adapter for Alcatel-Lucent 5620 SAM EMS, the Topology Split Manager receives the topology information that is needed by the IP Availability Managers to model networks that are populated with Alcatel-Lucent devices. The VMware Smart Assurance Adapter for Alcatel-Lucent 5620 SAM EMS User Guide describes the Adapter for Alcatel-Lucent 5620 SAM EMS in detail and presents configuration procedures for the Adapter.

After the topology split, the IP Availability Managers discover, monitor, and analyze the devices and network connectivity in their respective domains, and send topology and event information to the Global Manager. The Global Manager integrates the topology and event information to acquire the complete topology of the managed IP network domain and to diagnose problems and impacts for the managed IP network domain.

The Topology Split Manager is the central point for topology management. All topology changes are made through the Topology Split Manager rather than through the IP Availability Managers that manage the domains.
