摘要
An apparatus includes: an adaptive declustered RAID array configured of data storage devices (DSDs), the DSDs comprise data chunks allocated as data, a local parity, or a global parity; and a controller configured to generate a reliability indicator reflective of a reliability status of at least a portion of the adaptive declustered RAID array for reallocating the data chunks by dynamically increasing or decreasing the data chunks allocated as the local parity, the global parity, or a combination thereof.
