Abstract

SSD service life is extended by monitoring wear-level and prompting relocation of unstable data out of SSDs that have reached a soft wear-level threshold such that those SSDs do not contain unstable data when those SSDs reach a hard wear-level threshold. The progression of SSD wear-level is forecasted using an ARIMA algorithm. Unstable data on SSDs between predicted times of reaching the soft and hard thresholds is replaced by stable data from SSDs that have not reached the soft wear-level threshold. The stable data may be snapshot data and deduplicated data and deduplication hashes characterized based on number of references. SSDs that reach the hard threshold without unstable data can remain in service for read IOs until being replaced.
