    • 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.
    • 一种基于磁盘的档案存储系统(20),包括存储单元(26),存储单元(26)被配置为存储归档数据,包括至少一个磁盘主轴以磁性地存储档案数据;互连(24) 存储单元。 在一个实施例中,系统包括多个存储单元,每个存储单元包括至少一个盘轴。 控制单元(22)控制存储命令以选择性地使存储单元关闭或上电,进入运行模式或待机模式,使盘的主轴旋转或旋转 并且对存储在存储系统中的所有归档数据执行数据完整性检查。 在各种其它实施例中,当数据完整性检查识别可校正错误时,控制单元运行扩展磁盘主轴的寿命和寿命的算法,优化功耗并执行数据迁移。
