TRANSPARENT MIGRATION OF FILES AMONG VARIOUS TYPES OF STORAGE VOLUMES BASED ON FILE ACCESS PROPERTIES

摘要

periodically checking a tag in a file stored on one of a plurality of storage volumes in the storage domain, wherein the tag identifies a pattern of prior access to the file (402); determining whether the access pattern matches a storage classification for the one of the plurality of storage volumes on which the file is stored (404); and when the access pattern does not match the storage classification for the one of the plurality of storage volumes, moving the file to another one of the plurality of storage volumes with a storage classification that matches the access pattern of the file when available (408).
