Abstract
A data storage system is disclosed that utilizes garbage collection and hybrid self-mapping for managing system data. In one embodiment, a system data region having an amount of valid system data that is below a threshold is freed. Write amplification associated with managing and storing system data can be reduced at least in part because only valid system data can be copied during garbage collection of the selected region. Mapping information associating system data with physical locations in non-volatile storage where system data is stored can be generated, which can reduce system data reconstruction time during start-up of the data storage system. Increase in efficiency and reduction in startup and initialization time can be attained.
