Migration decision window selection based on hotspot characteristics

A computer program product for migrating storage hotspots in a multi-tier enterprise storage system, comprising:

• a non-transitory computer readable storage medium storing computer executable instructions, when executed by a processor of the multi-tier enterprise storage system, the computer executable instructions cause the processor to perform:
• collecting usage statistics for data stored in the multi-tier enterprise storage system in real-time;
• identifying a plurality of hotspots from data stored in the multi-tier enterprise storage system based on the usage statistics collected;
• determining one or more characteristics of the plurality of hotspots identified;
• calculating an average lifespan of the plurality of hotspots identified based on the one or more characteristics of the plurality of hotspots identified;
• and
• migrating the plurality of hotspots identified in real-time to one or more high performance storage devices based on the average lifespan of the plurality of hotspots identified and the one or more characteristics of the plurality of hotspots identified.
