Parity Striping of Disk Arrays: Low-Cost Reliable Storage with Acceptable Throughput

  title={Parity Striping of Disk Arrays: Low-Cost Reliable Storage with Acceptable Throughput},
  author={Jim Gray and Bob Horst and Mark Walker},
An analysis of mirrored discs and of RAIDS shows that mirrors have considerably better throughput, measured as requests/second on random requests of arbitrary size (up to IMB). Mirrors have comparable or better response time for requests of reasonable size (less than 1OOKB). But mirrors have a 100% storage penalty: storing the data twice. Parity striping is a data layout that stripes the parity across the discs, but does not stripe the data. Parity striping has throughput almost as good as… CONTINUE READING
