CHAPTER 6 - SUMMARY AND RECOMMENDATIONS

Abstract

Computer capacity planning is the process of monitoring and projecting computer workload and planning for the change or expansion of computer configurations to satisfy future demands in a cost-effective manner. Because of the large amount of resources involved in most major equipment acquisitions, even a small improvement in the capacity planning process can result in significant cost savings. This chapter discusses the measures that can help bring theory and practice closer together to improve the quality of the capacity planning process, which contributes to cost savings. A successful data center relies on a cost-effective capacity planning program that can ensure sufficient computer capacity to provide satisfactory services to its users. Continuing education on the up-to-date development of capacity planning methodologies should be useful for capacity planners. These courses should emphasize the fundamental concepts and rationale underlying the methods. Capacity planners are responsible for selecting the most cost-effective methodology in a given situation and environment. Workload forecasting is the weakest element in the process of computer capacity planning.
