With 400 GB native capacity (800 GB compressed) and SAS-optimized throughput, the solution delivers reliable 120 MB/s write speeds, reduces nightly backup windows by 45 %, and lowers storage TCO by 30 %, while ensuring data integrity and rapid restore capabilities.
Regulatory Compliance & Long-Term Archival in Life Sciences
A biotech research facility leverages the EH847B-HP LTO-3 Ultrium 920 SAS drive for immutable, WORM-capable archiving of clinical trial data to satisfy HIPAA and FDA 21 CFR Part 11 requirements. Integrated with IBM Spectrum Protect, the drive provides secure AES-256 encryption, 15-year retention and audit-ready media tracking. This approach mitigates audit risk, ensures chain-of-custody compliance and reduces archival infrastructure costs by 40 % over ten years.
Disaster Recovery & Offsite Replication for Manufacturing
A global manufacturing enterprise deploys EH847B-HP LTO-3 Ultrium 920 SAS drives in a remote tape library to capture monthly system snapshots across multiple plants. Utilizing high-speed SAS connectivity and hardware-based compression, each 4 TB dataset is written in under 30 minutes. Encrypted cartridges are rotated offsite, enabling sub-4 hour RTO, fortified business continuity and a 50 % reduction in DR infrastructure expenditure.
