Types of models
- Workload Model
- R/W Ratio
- % Sequentiality
- Disk Access Patterns
- Partial Determinism
- Storage System Model
- Single disk R/W access times
- R/W accesses in disk arrays: Including overheads due to parallel I/Os, RMW/mirroring, etc
- BORG Model
- Amount of data transferred: Depends on the size of the OPT and workload
- BOPT hits
