ABSTRACT:
A library storage system is implemented to comprise a redundant array of inexpensive libraries (RAIL). The system includes removable storage media which may be logically configured into groups (libraries) and subgroups (media groups), such that each may element may be identified and referenced by number. The configuration of libraries allows for redundant data storage as well as error detection and correction via parity schemes. When substitution of storage media is performed, a RAIL controller inspects the appropriate libraries (by matching ID numbers) to ensure that substitute media are stored in the correct locations.
