HPE LTO-9 Ultrium 18 TB Data Cartridge (C7979A)
Catalog entry for the removable storage medium itself, not a drive or reader. Confirm the complete model marking and the host's manual before use.
MEDIA ONLY: HPE LTO-9 Ultrium 18 TB Data Cartridge (C7979A). The named capacity/format and compatibility are limited to this model and generation; the drive or reader is separate.
Capacity, format and compatibility
| Manufacturer model / format | LTO Ultrium generation 9; C7979A |
|---|---|
| Nominal capacity | 18 TB native; compressed rating is data-dependent. Compression, if used by the drive/software, is data-dependent and does not guarantee additional capacity. |
| Reader or drive support | Use an LTO-9-compatible drive; check its manual for supported media generations and firmware. |
| Write protection | Physical LTO write-protect switch; verify protected status in the drive or backup software. |
| Revision and compatibility limit | Match the printed part number, standard revision, capacity class, media generation, host manual, and (where relevant) drive firmware. Connector or shell fit by itself does not demonstrate compatibility. |
Handling, longevity and preservation
No finite shelf-life or archival-life guarantee is claimed here: media longevity depends on the specific medium, age, environment, use, and condition. Keep original labels and packaging, avoid contamination and unapproved handling, inventory the exact model and generation, and periodically read/verify contents. Keep multiple independent copies and checksums; refresh or migrate data before media or reader support becomes unavailable.
- Keep the medium clean, dry, labeled, and in its protective case or cap. Avoid touching contacts or exposed recording surfaces; do not write while the host is busy or remove during activity.
- Use the documented mechanical lock or host-level read-only mode where available, but do not treat it as a substitute for a verified backup.
- Record the exact reader/drive, host, firmware, filesystem, model, and any write-protect state used during recovery or migration.
