Abstract
An apparatus, system, and method are disclosed for relocating logical array hot spots. An organization module organizes a plurality of logical arrays. Each logical array comprises a plurality of logical segments from a plurality of storage devices and configured to store data. An identification module identifies a hot spot on a first logical array if accesses to the first logical array exceed an access threshold. A migration module dynamically migrates a first logical segment from the first logical array to a second logical segment of a second logical array, wherein the migration is transparent to a host and data of the first logical segment is continuously available to the host.
