摘要

硬盘驱动器具有多层容错机制,可防止数据丢失。然而,一些故障偶尔会破坏整个机制集。为了防止这种情况发生,我们依靠故障预测机制来发出警报,并提供足够的警告,以允许将有风险的数据复制到安全位置。常见的故障预测技术是监控软错误的发生,并在软错误率超过设定的阈值时触发告警。本研究使用从超过50,000个客户部署的磁盘驱动器中收集的数据来检查软错误和故障之间的关系,特别是表现为硬错误的故障。数据分析表明,软误差本身不能作为硬误差的可靠预测因子。然而,在软错误确实能准确预测硬错误的情况下,存在足够的警告时间来采取预防措施。

A study of soft error consequences in hard disk drives
Hard disk drives have multiple layers of fault tolerance mechanisms that protect against data loss. However, a few failures occasionally breach the entire set of mechanisms. To prevent such scenarios, we rely on failure prediction mechanisms to raise alarms with sufficient warning to allow the at-risk data to be copied to a safe location. A common failure prediction technique monitors the occurrence of soft errors and triggers an alarm when the soft error rate exceeds a specified threshold. This study uses data collected from a population of over 50,000 customer deployed disk drives to examine the relationship between soft errors and failures, in particular failures manifested as hard errors. The data analysis shows that soft errors alone cannot be used as a reliable predictor of hard errors. However, in those cases where soft errors do accurately predict hard errors, sufficient warning time exists for preventive actions.
