摘要
Various embodiments for managing data stored in a tiered data storage environment, by a processor device, are provided. A data file is proactively migrated from a lower tier to a higher tier of the tiered data storage environment by using a multidimensional algorithm adopting an actual frequency of access of the data file to gauge a slope of a predicted frequency of access of the data file. The data file is migrated from the lower tier to the higher tier only if each of a plurality of criteria of the multidimensional algorithm is satisfied.
