Self Monitoring Analysis and Reporting Technology (SMART) Copyback

Users have variety of requirements of data storage that can be addressed using Self Monitoring Analysis and Reporting Technology (SMART) Copyback. It is estimated that over 94% of all new information produced in the world is being stored on magnetic media, most of it on Physical Disks (PD). Moreover, larger population studies rarely have the infrastructure in place to collect health signals from components in operation, which is critical information for detailed failure analysis. It presents the data collected from detailed observations of a large disk drive population in production Internet services deployment. Analysis identifies several parameters from the Physical Disks (PD), self monitoring facility (SMART) that correlate highly with failures. Despite this high correlation conclude that models based on SMART parameters alone are unlikely to be useful for predicting individual drive failures. Surprisingly, it found that temperature and activity levels were much less correlated with Physical Disk (PD) failures.
