Abstract
A method for preemptively migrating data in a tiered storage system is disclosed. In one embodiment, such a method includes identifying a regularly scheduled event that is associated with an increase in I/O activity. The method further identifies a virtual storage resource (e.g., file, data set, logical volume) associated with the increase in I/O activity. A timeline is then analyzed to determine timing for the regularly scheduled event. The method automatically promotes the virtual storage resource from lower-performing storage media to higher-performing storage media immediately prior to a start of the regularly scheduled event. The method automatically demotes the virtual storage resource to the lower-performing storage media after completion of the regularly scheduled event. A corresponding system and computer program product are also disclosed.
