Execution

python3 hash.py

This program achieves following functions:

• Derive deduplication rate of input with different chunks size
• Output fingerprints file for future use (e.g., storage simulator).
• Estimate metadata overhead produced by dedup under CAFTL mechanism for SSD.
  • Mapping: Primary Mapping Table (PMT) and Secondary Mapping Table (SMT)
  • Out of Band (OOB): implemented by Reverse Mapping for storing metadata
