Manage Performance and Capacity

The need to manage performance and capacity of IT resources requires a process to periodically review current performance and capacity of IT resources. This process includes forecasting future needs based on workload, storage and contingency requirements. This process provides assurance that information resources supporting business requirements are continually available.

Performance and Capacity Planning

Establish a planning process for the review of performance and capacity of IT resources to ensure that cost-justifiable capacity and performance are available to process the agreed-upon workloads as determined by the SLAs. Capacity and performance plans should leverage appropriate modeling techniques to produce a model of the current and forecasted performance, capacity and throughput of the IT resources.

Current Performance and Capacity

Assess current performance and capacity of IT resources to determine if sufficient capacity and performance exist to deliver against agreed-upon service levels.

Future Performance and Capacity

Conduct performance and capacity forecasting of IT resources at regular intervals to minimize the risk of service disruptions due to insufficient capacity or performance degradation, and identify excess capacity for possible redeployment. Identify workload trends and determine forecasts to be input to performance and capacity plans.

IT Resources Availability

Provide the required capacity and performance, taking into account aspects such as normal workloads, contingencies, storage requirements and IT resource life cycles. Provisions such as prioritizing tasks, fault-tolerance mechanisms and resource allocation practices should be made. Management should ensure that contingency plans properly address availability, capacity and performance of individual IT resources.

Monitoring and Reporting

Continuously monitor the performance and capacity of IT resources. Data gathered should serve two purposes:

To maintain and tune current performance within IT and address such issues as resilience, contingency, current and projected workloads, storage plans, and resource acquisition
To report delivered service availability to the business, as required by the SLAs

Accompany all exception reports with recommendations for corrective action.
