Abstract
An embodiment for a method of cost-aware tiering for data storage. The embodiment may detect data to be stored in one or more storage systems and gathering access and usage information. The embodiment may maintain a first data structure including periods of activity below a defined threshold for the detected data, and a common data structure to identify and track application-wide data patterns. The embodiment may gather static pricing information and context pricing information for the one or more storage systems and calculate a tiering threshold corresponding to a continuous period of activity below a second defined threshold required for which local storage costs exceed a tiering cost. The embodiment may calculate for inactive data segments, probabilities of the inactive data segments remaining inactive for a duration that exceeds the calculated tiering threshold. The embodiment may calculate a risk score and generate a tiering list for storing the data.
