Optimizing Cauchy Reed-Solomon Codes for Fault-Tolerant Storage Applications

  title={Optimizing Cauchy Reed-Solomon Codes for Fault-Tolerant Storage Applications},
  author={James S. Plank},
In the past few years, all manner of storage systems, ranging from disk array systems to distributed and widearea systems, have started to grapple with the reality of tolerating multiple simultaneous failures of storage nodes. Unlike the single failure case, which is optimally handled with RAID Level-5 parity, the multiple failure case is more difficult because optimal general purpose strategies are not yet known. Erasure Codingis the field of research that deals with these strategies, and this… CONTINUE READING
