Hotspot detection and caching for storage devices |
摘要 |
A system includes a counting module, a region defining module, and a caching module. The counting module is configured to count a first number of accesses to a first region of a storage medium during a first time period. The counting module is configured to count a second number of accesses to the first region during a second time period following the first time period. The region defining module is configured to selectively define a second region and a third region within the first region when the second number of accesses is greater than the first number of accesses by a predetermined amount. The caching module is configured to selectively cache the second region into a cache memory when a third number of accesses to the second region during a third time period following the second time period is greater than a fourth number of accesses to the third region during the third time period.
