Abstract
A method includes determining to move an extent from a source-tier in a storage system to a destination-tier in the storage system, wherein a set of tracks of the extent is presently being accessed. In response to determining that a parameter of the extent exceeds a migration threshold, a destination-tier cache is populated with tracks as they are removed from a read-stack associated with the source-tier and/or a write-stack associated with the source-tier using a predetermined read-to-write ratio.
