Installation considerations

1000 devices x 100 data points per device = 100,000 data points

100000 / 300 seconds / 250 dps = 1.333 collectors

In this scenario, you would need one master and two collectors to prevent I/O overload.

For each use type, minimum memory and CPU requirements are shown in the following table.

Master 16 GB 8 cores 32+ GB 8+ cores Memory and CPU requirements increase

with the number of datapoints, de-

vices/components, and concurrent users.

Remote collector 8 GB 4 cores 16 GB 8 cores SSD storage is also recommended.

Disk storage requirements are shown in the following table:

1.3.1. Large or complex deployments

If you are planning to monitor a large number of devices (with a significant number of data points for each device), or

a network with complex topology, there are additional requirements and configurations to consider. Contact Zenoss

Professional Services for deployment planning assistance.

1.3.2. Storage considerations

Resource Manager is a highly I/O-intensive application; as a result, it usually performs best when using direct, attached

storage. However, an appropriately tuned SAN/NAS environment can also be used effectively with a Resource Man-

ager installation.

1.3.3. Firewall security considerations

Resource Manager relies on specific ports to communicate with remote hosts and devices. Appendix B, "Port require-

ments", provides comprehensive descriptions of the ports, protocols, and traffic flows associated with each Resource

Manager daemon.

Because Resource Manager supports a wide variety of deployment architectures, the installation instructions do not

include firewall configuration steps. Consult with your Zenoss representative to plan your deployment, and then con-

figure Resource Manager host firewalls to support your architecture.

1.4. Server hardware configuration

1.4.1. File system configuration

Resource Manager stores performance data in individual RRD files. Performance updates are 8 bytes per data point,

which translates to a 4KB file system block update. Under such a high volume/low throughput usage pattern, journaled
