Abstract
A virtual logical unit that stores learning metadata is allocated in a first storage server having a first plurality of clusters, wherein the learning metadata indicates a type of storage device in which selected data of the first plurality of clusters of the first storage server are stored. A copy services command is received to copy the selected data from the first storage server to a second storage server having a second plurality of clusters. The virtual logical unit that stores the learning metadata is copied, from the first storage server to the second storage server, via the copy services command. Selected logical units corresponding to the selected data are copied from the first storage server to the second storage server, and the learning metadata is used to place the selected data in the type of storage device indicated by the learning metadata.
