Abstract
A system for mapping between logical addresses and storage units of a plurality of storage volumes which comprise a storage system. For each volume, logical addresses are mapped to storage units using a volume mapping table. Each volume mapping table is comprised of a plurality of segments. Each segment need not be contiguously allocated to another segment of the same table. Thus, each volume mapping table can be independently expanded or reduced without affecting other volume mapping tables. A hash function, a hash table, a segment table, and a redundancy group descriptor table may also be used to help manage the segments of the volume mapping tables.
