WORM functionality for LTO tape drives and media
Write-once-read-many (WORM) cartridges are designed for applications such as
archiving and data retention, and to prevent the alteration or deletion of user data.
They are also suitable for applications that require an audit trail.
The supported LTO tape drives include the WORM feature, which is supported by
the LTO WORM data cartridges.
The following WORM media traits reduce tampering with data:
v
The bottom of the WORM cartridge is molded in a color (gray) that is different
from rewritable cartridges.
v
A unique format is factory-written on each WORM cartridge.
v
The WORM cartridge's memory, along with its unique format, protects the
WORM character of the media.
Based on LTO technology, the format for the LTO WORM data cartridge provides
the same capacities as the equivalent LTO data cartridges.
Compatibility among LTO tape drives and cartridges
This section defines compatibility among generations of LTO tape drives and
cartridges.
“Mixed media in drives” on page 32 shows the compatibility among the LTO
drives and cartridges.
Note: Only LTO 5 and later tape drives are supported with the TS4500 tape
library.
