Step 3—Reporting Results
Step 3—Reporting Results
Sizing results are usually reported to the capacity-planning staff and management.
Useful reports describe the sizing staff’s assumptions, describe modeling results, list
alternatives, and provide recommendations.
Capacity Planning
Capacity planning consists of four steps:
1. Establishing the requirements and strategy
2. Instituting performance reporting
3. Developing a model of existing usage and using it to forecast future requirements
4. Developing, reviewing, and modifying the capacity plan
Step 1—Establishing the Requirements and Strategy
The capacity-planning requirements and strategy are based on the service-level
agreements. Planners determine how much capacity will be required in the future based
on an estimated future workload and the service agreements.
Step 2—Performance Reporting
Performance reporting includes the following tasks:
•
Gathering information to determine how current capacity is being used and to
determine when additional capacity will be needed. Typically, planners determine
what should be measured and how often, and the operations staff executes command
files to generate the measurements.
Tandem provides a number of tools to help planners gather and analyze data. These
tools are described later in the subsection “Performance Management Tools.”
•
Establishing a reporting schedule.
Management usually specifies how often planners should deliver reports and to
whom. You might want reports twice a month, once a month, or quarterly. If
planners find performance problems that can be corrected without additional
capacity, they should report their findings to the operations staff.
•
Delivering reports, including capacity-usage reports, and tuning recommendations.
Supply summary information on system usage in graphic and tabular form to senior
management and to the user community.
