Abstract

Method and apparatus for indexing subblocks in a reduced-redundancy storage system. Each subblock is hashed to an K-bit key and an entry for the subblock added to an index data structure comprising of a tree of hash tables. In a further aspect, by replacing the top of the tree with an array, the data structure can achieve O(1) access time for random keys while still providing relatively smooth growth.
