The IBM Systems Workload Estimator (a.k.a., the Estimator or WLE) is a web-based sizing tool for IBM Power Systems, 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 Estimator allows measurement input to best reflect your current workload and provides a variety of built-in workloads to reflect your emerging application requirements. Virtualization can be reflected in the sizing to yield a more robust solution, by using various types of partitioning and virtual I/O. The Estimator will provide current and growth recommendations for processor, memory, and disk that satisfy the overall customer performance requirements.
The Estimator supports sizings dealing with multiple systems, multiple partitions, multiple operating systems, and multiple time intervals. The Estimator also provides the ability to easily do multiple sizings. These features can be coordinated by using the functions on the Workload Selection screen.
