Interpretation: multi-fault exp’ts
Linux and Windows have different reconstruction philosophies
- Linux uses idle bandwidth for reconstruction
- little impact on application performance
- increases length of time system is vulnerable to faults
- Windows steals app. bandwidth for reconstruction
- reduces application performance
- minimizes system vulnerability
- but must be manually initiated (or scripted)
- Windows favors fault-tolerance over performance; Linux favors performance over fault-tolerance
- the same design philosophies seen in the single-fault experiments
