DISK-BASED ARCHIVAL DATA STORAGE SYSTEM AND METHOD

摘要

A disk-based archival storage system (20) including a storage unit (26) configured to store archival data, including at least one spindle of disks to magnetically store archival data, an interconnect (24) to either archive to or retrieve data from the storage unit. In one embodiment, the system includes a plurality of the storage units each including at least one spindle of disks. The control unit (22) controls the storage commands to selectively cause the storage unit(s) to shut down or power up, enter a running mode or a standby mode, cause the spindle of disk(s) to either spin up or spin down, and to perform a data integrity check of all the archival data stored in the storage system. In various other embodiments, the control unit runs algorithms that expand the lifetime and longevity of the disk spindles, optimizes power consumption, and performs data migration when a data integrity check identifies correctable errors.
