ABSTRACT:
A file server includes active storage containing frequently accessed files, and active/inactive disk drives for containing infrequently accessed files. Groups of the files having become inactive in the active storage are successively migrated to respective evacuated active/inactive disk drives so that each active/inactive disk drive is loaded with files having a similar probability of access when access to the active/inactive disk drive reaches an inactivity threshold for powering down the active/inactive disk drive. Storage of the active/inactive disk drives is reclaimed when an oldest group of the files is archived or when an active/inactive disk drive is evacuated by migrating files from the active/inactive disk drive to storage having been released in other disk drives by promotion of files for client access to the promoted files. Therefore, recovery of storage can be planned and scheduled in advance and performed efficiently in a background process.
