Abstract
A method and a system for data migration on a multi-tiered storage system are provided. The method can include receiving a migration task indicating a dataset to migrate. The method can further include building a plurality of buffers onto at least one high-performance storage tier. The high-performance storage tier can be based on the read speed of that tier. The method can also include referencing a shadow mapping to locate physical data from the dataset stored on a first buffer. The method can include migrating the physical data from the first buffer to a migration destination. The method can further include deallocating the first buffer. The deallocation can allow allocation of additional physical data onto the first buffer for migration.
