2 Preparing for installation

The following information describes IMC installation requirements for both hardware and software.

Hardware requirements

The following terms are used:

• Node—IMC servers, database servers, and devices managed by IMC are called "nodes."

• Collection unit—Represents a performance instance collected every 5 minutes. When a

performance instance uses another collection interval, it corresponds to a number of collection units

calculated with the formula: 5 minutes/instance collection interval in minutes.

For example, the collection interval is set to 10 minutes for all performance instances. A monitored

device contains 1 CPU, 1 memory bar, and 10 interfaces. To collect performance data for CPU,

memory, response time, reachability rate, and interface send and receive rates, the total collection

units of the device are: (1+1+1+1+(10×2))×5/10=12.

• CPU

—The frequency of the CPU must be no less than 2.0 GHz.

• Java heap size—Maximum memory size to be used by Java processes on the IMC Web Server.

The hardware requirements of IMC vary with the components and networking circumstances. For more

information, see the release notes of each component.
