AK381SB Use Case
Long-Term Regulatory Archival for Financial Institutions
A multinational investment bank deploys the HPE StoreEver MSL4048 0-drive 48-slot Tape Library to meet stringent SEC and FINRA retention mandates. IT teams schedule automated monthly full backups and incremental snapshots to LTO-8 cartridges, storing up to 1.2PB native capacity on-site. This use case delivers audited, WORM-compliant archives with sub-second retrieval metadata, achieving 40% lower total cost of ownership (TCO) compared to disk-only solutions and ensuring uninterrupted compliance during audits.
Tiered Disaster Recovery with Off-Site Tape Rotation
A global manufacturing enterprise integrates the HPE StoreEver MSL4048 tape library into its multi-site DR strategy. Data center backups run nightly via deduplicated snapshots to LTO-9 tapes, which are then cataloged and rotated off-site using a secure logistics provider. This approach provides air-gap security against ransomware, rapid full-site recovery capability, and predictable operational costs, reducing recovery time objectives (RTO) to under four hours and ensuring business continuity.
Scalable Media Asset Preservation for Post-Production Studios
A leading film post-production studio leverages the HPE StoreEver MSL4048 0-drive library to archive high-resolution raw footage and finished cuts. With 48 slots for up to 10TB LTO-8 cartridges, editors offload inactive projects to tape, freeing up SAN/NAS storage for active workflows. The solution offers 1:2 compression ratios, centralized cataloging via HPE TapeAssure, and rapid restore of specific reels, reducing nearline storage costs by 70% and securing invaluable master content over multi-decade lifecycles.
