Behavior-driven die management on solid-state drives

Abstract:

Systems, methods, and software are disclosed herein that enhance the management of storage sub-systems with solid-state media. In various implementations, a method comprises collecting time series data indicative of an accumulation of bad blocks within dies on one or more solid-state drives. For one or more of the dies, the method includes identifying one or more behaviors of a die based at least on a portion of the time series data associated with the die and determining to retire the die based at least on one or more identified behaviors of the die. One or more of the dies on the one or more solid-state drives may then be retired accordingly.
