Installation Considerations

Type Disk Storage

Zenoss DataStore 50GB

Table 1.2. Disk Storage Requirements

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. Other 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 Manager installation.

1.4. Server Hardware Configuration

1.4.1. File System Configuration

Resource Manager stores gathered 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 file systems can be detrimental to IO performance.

If possible, create a separate, non-journaled partition for $ZENHOME/perf (for RPM, /opt/zenoss/perf).

For more information about file system performance tuning and increasing RRD performance, read the section

titled "Increasing RRD Performance" in the Performance Tuning chapter of this guide, or browse to:

1.4.2. Deploying in a Virtualized Environment

Resource Manager is deployed successfully at many sites in a virtualized environment. However, this type

of environment requires additional configuration to ensure there is no resource contention for the Resource

Manager application (CPU, memory, IO). Zenoss Professional Services can provide expert assistance in this

area.

1.5. Post-Installation Performance Tuning Tasks

After your installation is complete, there are several configuration settings you should adjust to maintain proper

performance. Based upon the size of your planned deployment, changes to the database configuration, as well

as tuning of the Zope configuration file, are required. See the chapter titled "Performance Tuning" in this guide

for more information.
