About ISP concepts
The following table shows some simple examples of templates and the
capabilities that they might provide:
See “Volume template” on page 182.
About template sets
A template set consists of related capabilities and templates that have been
collected together for convenience. Associating a template set with a storage
pool is equivalent to associating each of its member templates separately with
the storage pool.
See “Template set” on page 178.
About user templates
A user template (or user-defined template) defines an arbitrary collection of
capabilities, templates and rules to which you want volumes of a certain type to
conform. For example, you might want all volumes that you create to store
database tables to share the same reliability and performance capabilities, and
also that they only be allocated from a restricted set of storage.
It is useful to create user templates if you regularly create volumes with similar
capabilities.
