Installations today process different types of work with different response times. Every installation wants to make the best use of its resources and maintain the highest possible throughput and achieve the best possible system responsiveness.
With workload management, you define performance goals and assign a business importance to each goal. You define the goals for work in business terms, and the system decides how much resource, such as CPU and storage, should be given to the work to meet its goal.
An installation should know what it expects to accomplish in the form of performance goals, as well as how important it is to the business that each performance goal be achieved. With workload management, you define performance goals for work, and the system matches resources to the work to meet those goals, constantly monitoring and adapting processing to meet the goals. Reporting reflects how well the system is doing compared to its goals.
Figure 1 shows a high level overview of the workload management philosophy. The following section explains the performance administration and performance management processes.
