Small Deployment For Up To 15,000 Metrics Per Second

The following information describes the requirements for a small deployment that is intended to support 15,000 metrics per second, for monitoring up to 100,000 devices and components. This deployment can be configured on the following four-host virtual machine environment:

One CA Performance Center host
One Data Repository host
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 the Data Repository host:

Component	Requirement
Operating system	Red Hat Enterprise Linux 5.x for x64 Red Hat Enterprise Linux 6.x for x64 Note: Upgrading an existing RH5 Vertica installation to an RH6 installation is not supported.
Processor	2 dedicated virtual CPUs
Processor speed	2.0 GHz
Memory (RAM)	16 GB
Disk space	3 partitions are required for the following directories: catalog directory data directory backup data directory Note: For information about disk space, see the system sizing tool, which is available in the 'Recommended Reading' section on support.ca.com.
Disk input/output	200 Mega Bytes/second

Data Aggregator Requirements

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

Component	Requirement
Operating system	Red Hat Enterprise Linux 5.x for x64 Red Hat Enterprise Linux 6.x for x64 Note: Upgrading an existing RH5 Vertica installation to an RH6 installation is not supported.
Processor	2 dedicated virtual CPUs
Processor speed	2.0 GHz
Memory (RAM)	16 GB
Disk space	50 GB Note: If Data Export will be used for one hour of data export, a second, separate 5 GB partition is required.
Disk input/ouput	100 Mega Bytes/second

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:

Component	Requirement
Operating system	Red Hat Enterprise Linux 5.x for x64 Red Hat Enterprise Linux 6.x for x64 Note: Upgrading an existing RH5 Vertica installation to an RH6 installation is not supported.
Processor	2 dedicated virtual CPUs
Processor speed	2.0 GHz
Memory (RAM)	12 GB
Disk space	50 GB
Disk input/output	100 Mega Bytes/second

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