Abstract
A content addressable storage (CAS) system is provided in which each storage unit is assigned to one of a plurality of sibling groups. Each sibling group is assigned the entire hash space. Within each sibling group, the hash space is partitioned into hash segments which are assigned to the individual storage units that belong to the sibling group. Chunk retrieval requests are submitted to all sibling groups. Chunk storage requests are submitted to a single sibling group. The sibling group to which a storage request is submitted depends on whether any sibling group already stores the chunk, and which sibling groups are considered full.
