Workload measurement and sizing tools
Capacity planning and performance management tools, which are available to
work with IBM i5/OS V5R3 and OS/400 V5R2, include:
IBM Eserver Workload Estimator
IBM Performance Management for Eserver™ iSeries
IBM Performance Tools for iSeries
PATROL for iSeries – Predict
IBM WebFacing Tool
IBM Disk Magic for Windows
The IBM Eserver Workload Estimator is a Web-based estimation tool. It
recommends a system that best fits overall system needs. It is described in the
following section.
Use PM Eserver iSeries (formerly called PM/400) to gather performance
information and pass the performance statistics to the IBM Eserver Workload
Estimator for projecting future needs of installed workloads.
For more information on PM Eserver iSeries, see:
http://www.ibm.com/servers/eserver/iseries/pm/
You can use Performance Tools for iSeries to measure resource utilization. Refer
to “IBM Performance Tools for iSeries (5722-PT1)” on page 759 for more
information.
Use PATROL for iSeries – Predict to perform detailed capacity planning and
“what-if” scenarios. For more information, see “PATROL for iSeries – Predict
(5620-FIF)” on page 761.
Use the IBM WebFacing Tool to convert 5250 source applications to applications
to run with the WebSphere Application Server. The IBM WebFacing Tool is
discussed in “IBM WebFacing Tool” on page 57.
Use Disk Magic for iSeries when IBM TotalStorage® Enterprise Storage Server®
(ESS) disk drives are in the configuration. See “Disk Magic for iSeries” on
page 56 for more information.
