Example simple deployment architecture

Use this example to familiarize yourself with the architecture of a simple Network Manager deployment.

Components

This example simple deployment consists of the following components:

  • One ObjectServer virtual pair.
  • One Dashboard Application Services Hub server.
  • One Network Manager installation running one domain with failover.
  • One instance of the NCIM topology database.

The following figure shows the architecture for this deployment.

Allocation of host workstations

The following figure shows an example allocation of host workstations for this deployment.

Note: If you have a particularly large topology, you might want to install the topology database on its own server. This decision depends on the specification of your machines and how you want to spread the load between them.

Steps to install a simple deployment

The following steps provide an overview of the tasks required for this deployment, and help plan for a similar deployment. The actual steps are detailed in Installing Network Manager and related products and Configuring Network Manager.

To install the deployment described above, perform the following steps:

  1. Install the topology database on host machine 3, create the necessary tables, and start the database.
    Note: The topology database must be installed and started before you start the Network Manager core components so that discovery data can be saved.
  2. Install the following ObjectServers and related components:
    1. Install the primary ObjectServer and the Bi-directional Gateway on host machine 1.
    2. Install the backup ObjectServer on host machine 2.
  3. Configure and run the ObjectServers.
    Note: The ObjectServers must be running before the Network Manager core components are started.
  4. Install the primary Network Manager core components on host machine 2.
  5. Install the backup Network Manager core components on host machine 1.
  6. Install the Network Manager GUI framework on host machine 3. The GUI framework includes the following software:
    • WebSphere Application Server
    • Dashboard Application Services Hub
    • Network Manager GUI components
    • Tivoli Netcool/OMNIbus Web GUI
    • Cognos Analytics
    Tip: If you install the Dashboard Application Services Hub on a machine with no other products, performance is likely to be better than if you install it on a machine with other products.
    Note: The Network Manager core components must be installed before the Network Manager GUI framework.
  7. Configure the primary Network Manager for failover and start it.
  8. Configure the backup Network Manager for failover and start it.
