Most error log analysis studies perform a statistical fit to the data assuming a single underlying error process. This paper presents the results of an analysis that demonstrates the log is composed of at least two error processes: transient and intermittent. The mixing of data from multiple processes requires many more events to verify a hypothesis using traditional statistical analysis. Based...
