LTO Ultrium WORM Tape Cartridge IBM 00V7591, LTO-6, 2.5 TB native

IBM LTO Ultrium WORM Tape Cartridge 00V7591 is a write-once, read-many (WORM) LTO-6 media with a native capacity of 2.5 TB. Designed for long-term retention and tamper-resistant archival storage, this cartridge delivers high-density offline storage for backups, compliance archives and regulated data sets. The media is compatible with LTO-6 drives and automated libraries that support LTO Ultrium cartridges and WORM functionality, enabling secure offline retention and simplified data lifecycle management.

Advantages

The tape cartridge provides WORM protection to prevent alteration or deletion of recorded data after writing, helping meet regulatory and audit requirements. With 2.5 TB native capacity, it supports high-density storage, reducing the number of cartridges required for large archives. LTO-6 transfer rates and cartridge reliability yield predictable offline performance and long shelf life for archived data. The removable, offline nature of the tape offers protection against online threats while enabling cost-effective retention compared with disk-based cold storage.

Suitable for

• Long-term archival of compliance, legal and financial records
• Offline backup storage and retention for enterprise environments
• Secure WORM-enabled retention to satisfy audit trails and regulatory requirements
• Integration with tape libraries and automated backup workflows

Key specifications

• Tape format: LTO-6 Ultrium
• Media type: WORM (write-once, read-many)
• Native capacity: 2.5 TB
• Compressed capacity: industry-standard up to 6.25 TB (depending on compression ratio and data type)
• Compatibility: LTO-6 drives and libraries that support WORM cartridges
• Form factor: Ultrium cartridge compatible with LTO tape robotic libraries

How to use

Handle the cartridge by its housing, avoiding contact with the tape window or exposed components. Insert the cartridge into an LTO-6 tape drive or compatible library bay following the drive manufacturer’s loading procedure. Initiate recording using backup or archiving software configured to use WORM media; once data is written and the WORM session is finalized, the media will prevent subsequent overwrite or deletion of the recorded content. Store cartridges in a controlled environment following vendor recommendations for temperature and humidity to maintain media integrity.

Usage recommendations

Label cartridges clearly with retention and content information before use, plan cartridge rotation for long-term retention policies, and verify restore procedures regularly. Maintain an inventory and use library management software to track WORM retention periods and ensure regulatory compliance. Avoid exposing cartridges to extreme temperatures, strong magnetic fields or prolonged direct sunlight to protect archived data.
