Depletable Storage Systems

Vijayan Prabhakaran, Mahesh Balakrishnan, John D. Davis, and Ted Wobber


Depletable storage systems use media such as NAND flash that has a limited lifetime, which decreases with more usage. Such systems treat write cycles, in addition to space, as a constrained resource of the system. Depletable storage systems must be equipped to monitor writes, attribute depletion to appropriate applications, and even control the rate of depletion. We outline the new functionalities enabled by depletion-aware mechanisms and discuss the challenges in building them.
