Hierarchical presentation Global Manager configuration

The hierarchical presentation configuration shown in Hierarchical presentation Service Assurance configuration uses multiple Global Managers at the presentation layer to address these configurations:

• More than 100 Service Assurance clients that connect concurrently: This includes Global Consoles, Web Consoles, Dashboard viewlets, and any adapters that connect to the Global Manager directly. It is recommended that each Global Manager at the presentation layer supports up to 100 concurrently connected clients. The example in Hierarchical presentation Service Assurance configuration, therefore, would support 200 clients.

• Geographically separate groups of clients: In these cases, using a standard Global Manager configuration would force a group of clients to connect to a Global Manager over a high-latency link. Additional Global Managers at the presentation layer would be located in the same geographical area as the groups of clients.

  To ensure that acknowledgements and ownership of notifications are properly propagated, some customization may be required.
