Disk drives fail at an average annual rate of ~2%. Any system with Availability and Durability requirements must mitigate for such failures through a redundancy technique such as RAID, Erasure Coding, Replication or Backup.

With the wealth of monitoring data available nowadays and the ability to process the data in near real-time, can we predict such failures? How well can we do it? And how would that impact how we design and operate large distributed systems?

We examine and motivate predictive failure detection in the context of Availability, Rebuild Times and Recovery Objectives of large systems. We then train and evaluate multiple models achieving favorable accuracy (97.5%) to common datacenter practices. We demonstrate how we can tune our learners to achieve different Precision and Recall objectives thus improving Availability, Protection or Operational Efficiency.
