Abstract
The described technology is generally directed towards maintaining a heat score per file based on a file's access/activity level, and using the heat score to re-tier files from faster to slower storage and vice-versa. Files on a slower tier that have more activity are thereby moved ('up-tiered') to a faster access storage tier, while the files that have less activity on the faster access storage tier are moved (“down-tiered”) to a slower access storage tier. The heat score for a file is increased based on more input-output operation activity, and decayed over time. The decaying can be based on a relative importance value (e.g., business value) assigned to the file or a domain that includes the file. Ordering the files based on their respective heat scores allows only a fraction of the files to be considered for re-tiering before the re-tiering moves are performed.
