A service model that is distributed across two or more Infrastructure Management Servers is called a distributed service model. When the number of CIs in a service model exceeds the maximum limit of CIs allowed in a single server, it is possible to distribute the model across multiple Infrastructure Management Servers. When creating a distributed service model, relationships must not span back and forth frequently across multiple servers (cells). An inappropriate model might deteriorate the performance of Infrastructure Management. The number of relationships spanning across multiple Infrastructure Management Servers must be kept to a minimum. A model must be present completely on a single Infrastructure Management Server as much as possible. For information about sizing the Infrastructure Management environment, see
Sizing charts and guidelines for event and impact management
BMC recommends using a discrete model over a distributed service model. Distributed service models must be created only in scenarios where it is not possible to have the complete service model on a single Infrastructure Management Server.
Infrastructure Management Server with a single service impact management cell
Each Infrastructure Management Server hosts parts of the service model or distinct service models.
- The impact management cells communicate with one another.
Service models on the Infrastructure Management Servers display CIs from one Infrastructure Management Server.
The Central Server displays all CIs across Infrastructure Management Servers.

Cross-launching to the Infrastructure Management Server and viewing the details in the Notebook pane
From the Events view or the Graph view in the operator console, you can cross launch to a Child Server from the distributed service model as shown in the following figure. For information about cross-launching, see Use cases for centralized service models.
The Notebook pane seamlessly displays details of the remote CIs. The Related CIs pane allows you to identity causal CIs and launch to the respective Infrastructure Management Server.
