Towards Benchmarks for Availability, Maintainability, and Evolutionary Growth (AME) A Case Study of Software RAID Systems
Outline
Why benchmark AME?
Why benchmarks?
The components of AME
How can we measure availability?
Example Quality of Service metrics
Availability benchmark methodology
Methodology: reporting results
Case study
Benchmark environment: metrics
Benchmark environment: faults
Disk fault injection technique
System configuration
Results: single-fault experiments
System behavior: single-fault
System behavior: single-fault (2)
Interpretation: single-fault exp’ts
Results: multiple-fault experiments
System behavior: multiple-fault
Interpretation: multi-fault exp’ts
Maintainability Observations
Maintainability Observations (2)
Conclusions
Future Directions
