Breakdown for those w/o access.

The solution has three dimensions:

  • Workload-aware decision engine – analyzes the characteristics of a workload to pick the best config
  • Architecture synthesis – integrates five different RAID architectures into one system
  • Performance-Reliability-Cost cube model – a model to evalute and balance the factors

Result:

  • P95 latency reduced by 22%
  • 2x mean-time-to-data-loss (MTTDL)
  • TCO lowered by 18%
