Consult the following topics for guidance on when to deploy multiple BMC TrueSight Infrastructure Management Servers and best practices for deployment:
|Multiple server use case||Scenario|
|Capacity and scalability|
When a single BMC TrueSight Infrastructure Management Server cannot scale to the requirements for data collection and event management, deploy additional Infrastructure Management servers to manage a portion of the environment for data collection and event management.
For information about how to size the environment, see Sizing and scalability considerations and best practices.
When you have geographically dispersed data centers, secure zones, or environments with separate access controls.
|Development, test, and production environments for agent deployment|
When you want to establish separate development, test, and production environments for deploying PATROL Agents and managing your monitoring policies. For information about how to set a single point in the environment where all newly deployed BMC PATROL Agents can register into the solution stack, see Staging Integration Service host deployment and policy management for development, test, and production best practices.
You can also implement this scenario by using multitenancy. You define tenants for test, development, and production in the Presentation Server and manage the policies on a single Infrastructure Management Server.
When you have multiple tenants requiring physical segregation of the data. Each Infrastructure Management server is associated with a single tenant only. A specific tenant is associated with the Infrastructure Management Server when the server is registered as a component with the Presentation Server. Each Presentation Server can support up to five tenants.
In a multiple Infrastructure Management server deployment, service providers can designate to which environments the tenants will have access by supporting that environment.
Integrations to the Infrastructure Management server should be dedicated to the environment of the tenant associated with that server.
For information about setting up a multitenant environment, see .
You use Central Monitoring Administration to manage BMC PATROL configuration across one or more Infrastructure Management Servers. Central Monitoring Administration is installed with the Presentation Server and launched from the TrueSight console. BMC recommends implementing one of the following architectural deployments for multiple Infrastructure Management servers:
Updates to and deletion of existing policies that are already in production must use the policy export/import capability for creation, testing, and deployment to production. For more information, see.
These implementation architecture options are not installation options; they are choices for where you install the servers and how you connect them.
All BMC TrueSight Infrastructure Management Server versions must be the same in a single environment. The Infrastructure Management solution cannot support mixed versions of Infrastructure Management Servers and requires the same version of the Presentation Server with Central Monitoring Administration. For more information, see Infrastructure Management interoperability.
The first option is to implement a single Presentation Server with Central Monitoring Administration for scenarios that require multiple Infrastructure Management Servers, such as multiple tenants or separate environments for development, test, and production.
This option requires fewer infrastructure nodes and components. Only a singlehost is needed, and only a single Central Monitoring Administration instance is used.
This option might not be supported in some sites where all the necessary connections in the development, test, and production or separate tenant environments are not available or allowed to be connected over the network.
Due to the powerful ease of use, it is easier for administrators to unintentionally apply policies to production. However, this possibility can be managed.
The following figure illustrates a typical high-level logical architecture for an Infrastructure Management deployment using multiple BMC TrueSight Infrastructure Management Servers connected to a single BMC TrueSight Presentation Server with Central Monitoring Administration.
High-level architecture for multiple-server deployment with a single Presentation Server and Central Monitoring Administration
In the single Central Monitoring Administration architecture, a singlenode is used in the agent deployment process for all agents. All Infrastructure Management Servers leverage the single Central Monitoring Administration instance for managing the entire policy.
For the list of ports required in a multiple-server deployment, see Network ports.
The second option is to implement a separate Presentation Server and Central Monitoring Administration instance in each of the development, test, and production or tenant environments.
Creating, testing, and deploying monitoring policies into production or across multiple tenant environments requires additional effort because you have to export and import policy data from development to the test environment and from test to the production environments.
Policies can get out of sync across development, test, and production environments if not managed properly. Keeping them updated is more of a manual process supported by the export/import utility.
This deployment requires additional infrastructure nodes and components. Development, test, and production environments must each have a dedicatedhost and a dedicated instance of Central Monitoring Administration.
The following diagram illustrates the high-level architecture for multiple Central Monitoring Administration instances in the development, test, and production environments.
High-level architecture for multiple-server deployment with multiple Presentation Servers and CMA
In this architecture, each environment has its own dedicated Central Monitoring Administration instance and a. All policy application between environments is supported by the policy export/import utility.
In previous releases, the parent Infrastructure Management Server in a multiple-server deployment was known as the Central Server. In this release, the Central Server has been replaced by the Presentation Server for most deployments. However, a Central Server is still required for the following deployment use cases:
Distributed service models—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. This is optional. Distributed service models are enabled by the web services installed with the Infrastructure Management Servers. The Central Server acts as a single point of entry for users and provides a common point to access to service models. For the deployment architecture, see Infrastructure Management deployment with BMC Atrium CMDB. For information on sizing the deployment, see Sizing charts and guidelines for event and impact management.
BMC Cloud Lifecycle Management Integration—The integration allows IT Operations to monitor cloud constructs provisioned by BMC Cloud Lifecycle Management. This integration requires a Central Server to fetch cloud topology from BMC Cloud Lifecycle Management and push cloud constructs to the appropriate Infrastructure Management child servers. For the deployment architecture, see Infrastructure Management deployment integrated with BMC Cloud Lifecyle Management.
For information on how to configure a Central Server, see Configuring a BMC TrueSight Infrastructure Management multiple-server deployment.
|Component||Deployment best practice|
Install and use the administration console on a host separate from the Infrastructure Management Server. Use the instance of the administration console that is installed with the Infrastructure Management Server for emergency use only.
|Database||Review the Considerations for selecting the database for the Infrastructure Management Server. If using an Oracle database, follow the Considerations and best practices for deploying the Oracle database.|

|Integrations and Impact Integration Web Services|
Develop a clear strategy for assigning the PATROL Agents to each Integration Service. The Infrastructure Management Server does not auto-balance the load between PATROL Agents and Integration Services, so the initial assignment is important. Although at least one Integration Service must exist per network, a convention based on name or function (or simple round-robin assignment) within the network is acceptable as long as you are consistent and avoid overloading any one Integration Service.
