Failure Trends in a Large Disk Drive Population, Eduardo Pinheiro, Wolf-Dietrich Weber, Luiz André Barroso, 5th USENIX Conference on File and Storage Technologies (FAST 2007), 2007
“We have built an infrastructure that collects vital information about all Google’s systems every few minutes, and a repository that stores these data in timeseries format (essentially forever) for further analysis. The information collected includes environmental factors (such as temperatures), activity levels and many of the Self-Monitoring Analysis and Reporting Technology (SMART) parameters that are believed to be good indicators of disk drive health. We mine through these data and attempt to find evidence that corroborates or contradicts many of the commonly held beliefs about how various factors can affect disk drive lifetime. Our paper is unique in that it is based on data from a disk population size that is typically only available from vendor warranty databases, but has the depth of deployment visibility and detailed lifetime follow-up that only an end-user study can provide.”
