Adapting behavior of solid-state drive using real usage model

摘要

An embodiment is a technique to adapt behavior of a solid-state drive (SSD) to extend lifespan of the SSD. Real environmental information is received from an environmental processor. The real environmental information corresponds to an environment of the SSD. A behavior model is selected based on a real environmental model and an internal data usage model. If a new behavior model is selected, the environmental processor is informed about the new behavior model. The environmental processor sends control commands to a power management module to apply new power policy to the SSD. Information on the new behavior model is made available for query. If current behavior model is selected, the current behavior model is maintained.

1. A method comprising:
deriving a set of optimal solid-state drive (SSD) operations corresponding to a model environment and a model usage of a SSD in a real usage model, the real usage model being created from an environmental profile, a usage profile, and an initial usage model; obtaining an environmental parameter representative of a current environment and an usage parameter representative of a current usage of the SSD; asserting a match if the current environment and the current usage match with the model environment and the model usage, respectively; and adapting behavior of the SSD using the set of optimal SSD operations if the match is asserted.
