Determine the Service Assurance Configuration

A single
Global Manager
can support most
deployments, but there are cases where multiple
Global Manager
s are required. Use Determining the required Service Assurance Configuration to determine the
configuration required to support your managed environment. The first three columns in Determining the required Service Assurance Configuration identify the quantities that will determine the
configuration:
  • The Managed devices and applications column details the total quantity that will be managed in the
    deployment. This number should include estimates for growth.
  • The Underlying domains column details the total number of domains that will feed topology and events to the
    deployment.
  • The Concurrently connected clients column details the total number of
    clients that will be connected concurrently, including
    Global Console
    s, Web Consoles, Dashboard viewlets, and any adapters that connect to the
    Global Manager
    directly.

The columns in the Use this Service Assurance configuration section define recommendations to support the deployment:
  • The
    Global Manager
    configuration column details the recommendation for the number of
    Global Manager
    s, either a single one (Standard) or multiple (any of the hierarchical configurations). If a hierarchical configuration is recommended, the specific structure is also defined. The
    Global Manager
    configurations are explained in the following sections.
  • The
    Global Manager
    platform equipment tier columns define the hardware that is required to support the
    Global Manager
    s. For hierarchical configurations, two layers of
    Global Manager
    s are defined: an aggregation layer and a presentation layer.
    Domain Manager
    s connect to a
    Global Manager
    at the aggregation layer while
    clients connect to a
    Global Manager
    at the presentation layer. The table indicates the equipment required to support each layer. “Hardware for Service Assurance platform equipment tiers” provides definitions for the equipment tiers.
    Determining the required Service Assurance Configuration defines
    configurations for coherent deployments. It is possible to create separate deployments in a managed environment that do not feed events and topology to a single, central
    Global Manager
    . If this is the case, each of these deployments must be treated separately with distinct
    Global Manager
    configurations based on unique quantities for first three columns in Determining the required Service Assurance Configuration.
