Abstract
A method for managing a flash storage system includes reading flash data units from flash memory into a buffer, wherein each of the flash data units includes host data units, and determining an identifier for each host data unit. The method includes selecting a set of unique identifiers from the determined identifiers based on a number of host data units sharing the respective unique identifier. For each unique identifier in the set of unique identifier, the method includes designating one of the host data units as a master data unit, wherein the logical address of the designated host data unit is mapped to a physical address. The logical addresses of the other host data units sharing the unique identifier are remapped to the master physical address, and the physical addresses previously mapped to the remapped logical addresses are invalidated.
