Abstract
Technologies for high capacity storage servers with thin provisioning can support an increased storage capacity and an increased number of snapshots within a data storage system while maintaining a reduced memory footprint. Flexible virtual address translation can support both direct, and indirect, translation from a virtual address to an address in physical storage. A data structure, referred to as a volume table, may be provided for supporting the virtual to physical address translation. Multiple volume tables for the various volumes within a data storage system can be stored together in a global volume table. Granularities of storage allocation units, such as territories, provisions, and chunks can be reduced to improve efficiencies in the operation of the storage system. Processes for handling volume and snapshot I/O operations with various data structures can contribute to improved efficiencies while supporting increased storage capacities and an increased number of snapshots.
