Efficient distribution and selection of storage media in a storage medium library

A method comprising:

• determining a distribution for a plurality of distributable components within a storage medium library, wherein the storage medium library comprises a plurality of library units, wherein said determining the distribution for the plurality of distributable components within the storage medium library comprises,
• determining a count of the distributable components within the storage medium library;
• determining a count of all storage medium drives within the storage medium library;
• determining a first value by dividing the count of distributable components within the storage medium library by the count of storage medium drives within the storage medium library;
• determine a count of storage medium drives in a first of the plurality of library units;
• and
• determine a goal value by multiplying the first value by the count of storage medium drives in the first of the plurality of library units, wherein the goal value is a goal value of distributable component for the first of the plurality of library units;
• determining that the plurality of distributable components are not currently distributed across the storage medium library in accordance with the distribution;
• and
• responsive to said determining the distribution for the plurality of distributable components and said determining that the plurality of distributable components are not currently distributed across the storage medium library in accordance with the distribution, issuing a set of one or more commands to move one or more of the plurality of distributable components to different locations of the storage medium library in accordance with the distribution.
