The IBM® Systems Workload Estimator is a Web-based sizing tool for System i™, System p™, and System x™. You can use this tool to size a new system, to size an upgrade to an existing system, or to size a consolidation of several systems.
The Workload Estimator allows measurement input to best reflect your current workload; one method is by using data from Performance Management for System i. The Workload Estimator also provides a variety of built-in workloads to reflect your emerging application requirements. Virtualization can be used to yield a more robust solution. The Workload Estimator will provide current and growth recommendations for processor, memory, and disk that satisfy the overall client performance requirements.
