Abstract
Systems and methods for creating, reading, and writing compressed data for use with a block mode access storage. The compressed data are packed into plurality of compressed units and stored in a storage logical unit (LU). One or more corresponding compressed units may be read and/or updated with no need of restoring the entire storage logical unit while maintaining de-fragmented structure of the LU.
