In an Enterprise, it is very common that the IT department to manage the system performance in reactionary fashion, correcting performance problem as users report them.  In Information Technology, system administrators must prepare in advance in order to avoid performance bottlenecks altogether, using capacity planning to predicts in advance how the database, servers should be configured to adequately handle future workloads and sufficient to support and needed over some future period of time.

 

A typical capacity concern of many organization and enterprises is whether the resources will be in place to support and handle an increasing number of requests as the number of interactions increase or users increase. The successful capacity planner must know the trade-offs between the present and the future that overall prove to be the most cost efficient. The major concern for the capacity planner is to plan so well that new capacity is added just in time to meet the anticipated need but not so early that resources go unused for a long period.

 

With the information of Business forecasts and business plans of the organization, the capacity planner would imagine what the future needs will be. The capacity planner will take the consideration on the “What if” scenarios and what are the range of possibilities can be explored. Whenever, new technologies emerge, the capacity planner must revisit their plans base on the business strategies and forecasts plan.

 

Three basic steps for capacity planning:

  • Analyze Current Capacity

The current capacity of the system must be analyzed to determine how it is meeting the needs of the users.

 

  • Determine Service Level Requirements (SLR)

The capacity planning process is to categorize the work done by systems and to quantify users’ expectations for how that work gets done.

 

 

  • Planning for the Future

Finally, using forecasts of future business activity, future system requirements are determined. Implementing the required changes in system configuration will ensure that sufficient capacity will be available to maintain service levels, even as circumstances change in the future.
