Chapter 1. Installation Considerations

Read the following sections to learn more about installation requirements for the Service Resource Management

("Resource Manager") feature of Zenoss Service Dynamics™.

1.1. Installation Artifacts

Zenoss provides two RPM Package Manager (RPM) artifacts for Resource Manager server deployment:

• Resource Manager RPM - Includes the Resource Manager software and required ZenPacks

• Windows ZenPacks RPM - (Optional) Includes ZenPacks required for Windows monitoring

For detailed information about installing the RPMs, refer to one of the following chapters in this guide:

• Installing for RHEL 5 or CentOS 5

• Installing for RHEL 6 or CentOS 6

1.2. Operating System Requirements

Resource Manager can be installed on:

• Red Hat Enterprise Linux (5 or 6)

• CentOS (5 or 6)

1.3. Hardware Requirements

Hardware requirements for Resource Manager depend on a number of factors, including I/O, memory, CPU,

and the number of managed devices.

For a deployment with a low number of managed devices and data points (low I/O), only a single master is

required.

For a deployment with 1000 managed devices, assuming that:

• Each managed device averages 100 data points

• Collection maximum is 250 data points per second (measured on a 15000 RPM hard drive)

• Default cycle time is 300 seconds

You could calculate hardware requirements as:

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.

Type Memory CPU

Master 8GB 8 cores

Remote collector 4GB 4 cores

Table 1.1. Memory and CPU Requirements

Disk storage requirements are shown in the following table:

Type Disk Storage

Resource Manager 50GB
