Abstract
A data-relationship-based FAST cache system includes a storage controller that is coupled to first storage device(s) and second storage device(s). The storage controller identifies a relationship between first data stored in the first storage device(s) and second data stored in the first storage device (s), with the relationship based on a difference between a first number of accesses of the first data associated with a first time period and a second number of accesses of the second data associated with the first time period being within an access difference threshold range. Subsequent to identifying the relationship, the storage controller determines that the first data has been accessed in the first storage device(s) a number of times within a second time period that exceeds a FAST cache threshold and, in response, moves both the first data and the second data to the second storage device(s) based on the relationship.
