With the rapid growth of data and the growing demand from users on the system performance, data availability has become the most important issue in large-scale storage systems. Due to the ability to provide space-optimal data redundancy to protect against node failures, erasure codes have seen widely deployment. To ensure data availability, it is crucial to recover node failures quickly. In this paper, the authors propose PHR, a pipelined heterogeneous recovery optimization for failure recovery in RAID-6 coded storage systems.
