DATA STORAGE SYSTEM WITH DATA STORAGE DEVICES OPERATIVE TO MANAGE STORAGE DEVICE FUNCTIONS SPECIFIC TO A PARTICULAR DATA STORAGE DEVICE

摘要

Operations of a variety of components of a storage system stack are redefined to make the system more efficient when the underlying media has a “multi-log” type interface such as the case with NAND flash SSD memory or shingled magnetic recording media. The responsibilities of components of the storage system stack are modified such that each responsibility is performed at the most efficient component (level of abstraction) of the storage stack.
