CA Performance Management Data Aggregator Deployment Scenarios › Medium Deployment For Up To 75,000 Metrics Per Second

Medium Deployment For Up To 75,000 Metrics Per Second

The following information describes the requirements for a medium deployment that is intended to support 75,000 metrics per second, for monitoring up to 500,000 monitored devices and components. This deployment can be configured on the following six-host physical machine environment:

• One CA Performance Center host
• Three Data Repository hosts in a cluster
• One Data Aggregator host
• One Data Collector host

Note: For information about CA Performance Center system requirements, see the CA Performance Center Release Notes.

Data Repository Requirements

The following table lists the minimum system requirements for installing each Data Repository host.

Important! Although this deployment works with a single node Data Repository environment, we strongly advise a three-node cluster environment.

Data Aggregator Requirements

The following table lists the minimum system requirements for installing the Data Aggregator host:

Note: The data loading process has been rearchitected to persist all polled data temporarily to files on Data Aggregator before loading the data into Data Repository. Polled data files are removed once they are loaded into Data Repository. As a result, the amount of available disk space on Data Aggregator will fluctuate over time.

Data Collector Requirements

The following table lists the minimum system requirements for installing the Data Collector host.

Note: These requirements are for a Data Collector instance that is monitoring up to 500,000 devices and components. In practice, multiple lighter Data Collector instances can be substituted, as long as the combined capacity does not exceed 500,000 monitored devices and components. For example, you can use five virtual Data Collector instances to approximate one large one. You can see how many devices and components Data Collector is monitoring in the Data Collector List view. For more information about the Data Collector List view, see the Data Aggregator Administrator Guide.

Note: For information about prerequisite steps and installation, see the Data Aggregator Installation Guide.
