The SMS definitions are the mechanisms by which the results of your business analysis are implemented. The ideal groups, classes, and cycles identified during analysis must be translated into practical terms. This section discusses the OAM-related SMS parameters and how they can be used to customize OAM for your needs.
As in any translation process, compromises and approximations must be made. For example, you might have to make trade-offs between performance and cost (DASD versus optical versus tape storage) as you implement your storage management policy.
The choice you make for any single parameter has the potential to affect many other parameters. Be prepared to adjust those choices after installation, as you tune and refine your system.
