Determining library requirements

The number of libraries required for an OAM implementation is influenced by several factors:

Number of libraries required to hold library-resident cartridges.
Number of libraries required to satisfy the maximum retrieval rate of objects on optical, tape, or both types of storage.
Number of libraries required for the storage management cycle to complete within the allotted processing period.

The largest of the three numbers represents the number of libraries that you should plan to install. The following guidelines concerning libraries can help you evaluate your library needs.
