13.2 Model for performance evaluation

This section uses the example of the business system shown below to give a rough estimate of the increase in memory and disk space requirements incurred when JP1/IM is deployed.

Figure 13‒1: Example of business system operation (before JP1/IM deployment)

This system operates as follows:

• Batch processing of work tasks is handled by seven servers.

• Web server functionality is handled by three servers.

• There are 50 user PCs.

Monitoring tasks are divided among three operators (three monitor machines) as follows:

• Operator A monitors the status of batch processing.

• Operator B monitors the status of the Web servers.

• A system administrator monitors the entire system (including end-user PCs).

Organization of this section

• 13.2.1 User requirements

• 13.2.2 Memory, disk capacity, and database capacity required on a monitoring server

• 13.2.3 Memory and disk capacity required on a monitor machine
