TIERED DATA STORAGE SYSTEM WITH DATA MANAGEMENT AND METHOD OF OPERATION THEREOF

摘要

A method of operation of a data storage system includes: enabling a system interface for receiving host commands; updating a mapping register for monitoring transaction records of a logical block address for the host commands including translating a host virtual block address to a physical address for storage devices; accessing by a storage processor, the mapping register for comparing the transaction records with a tiering policies register; and enabling a tiered storage engine for transferring host data blocks by the system interface and concurrently transferring between a tier zero, a tier one, or a tier two if the storage processor determines the transaction records exceed the tiering policies register.
