Before you begin: Like storage classes, management
classes can be developed to meet a variety of needs. Develop as many
management classes as necessary to use the class transitions and storage
management cycles that are required by your business. To avoid processing
inefficiencies or unexpected results, or both, careful analysis of
the end results of class transition is critical for a successful implementation.
Perform the following steps to develop your management classes:
- Analyze your applications to plan for large groups of objects
that have the same management requirements. You can assign these objects
to one management class and store them together in one collection.
- Identify objects that are good candidates for early deletion or
class transition.
- Separate objects that do not need to be backed up from those that
do.
- Identify objects or collections that require immediate backup.
- Identify objects that require a delayed class transition.
- Identify objects with medium to low response-time requirements,
so that they can be moved to tape or optical storage as soon as possible.
- Use ISMF to define your management classes by selecting option
3, Management Class, from the ISMF Primary Option Menu for storage
administrators.
