Distributed Model
The Distributed model is suitable for most larger network environments in service providers and
Enterprises. The Web server, Application server, and Mediation server are installed on separate
servers without clustering. This model helps achieve better performance and helps when the
minimum hardware is not available for a single-server (standalone) installation.
You may also distribute the Database server if more than one database is required for redundancy
(that is, RAC, MHA, or Replication).
High Availability and Clustering Model
The Clustered model is suitable for best performance and high availability. If you cluster
components (in addition to distributing them), OpenManage Network Manager lets you use the
following features:
• Application server clustering (for redundancy and improved performance)
• Mediation server load balancing (with the Application server round robin process)
• Redundant Web servers
• Paired Database servers for database redundancy and failover
