Cartridge Compatibility

This table shows Ultrium data and cleaning cartridge compatibility with Ultrium tape

NOTE: The NEO 200s/400s tape libraries support only the Ultrium 4 and Ultrium 5 tape drives.

Capacity Scaling

To control the capacity of the cartridge (for example, to obtain a faster seek time) issue the
SCSI command SET CAPACITY.

Write Once, Read Many (WORM)

Certain records retention and data security applications require a Write Once, Read Many
(WORM) method for storing data on tape. The LTO Ultrium generation 5, 4, and 3 drives
enable WORM support when a WORM tape cartridge is loaded into the drive.

WORM Media

Because standard read/write media are incompatible with the WORM feature, a specially
formatted WORM tape cartridge is required.
Each WORM cartridge has a unique, worldwide cartridge identifier (WWCID), which
comprises the unique CM chip serial number and the unique tape media serial number. See
"Ordering Media Supplies" on page 6-11
appropriate WORM tape cartridges for your library.

Data Security on WORM Media

Certain built-in security measures help ensure that the data written on a WORM cartridge
does not become compromised, for example:
• The format of an Ultrium 5 1500 GB, Ultrium 4 800 GB, or Ultrium 3 400 GB WORM
Tape Cartridge is unlike that of standard read/write media. This unique format
prevents a drive that lacks WORM-capable firmware from writing on a WORM tape
cartridge.
• When the drive senses a WORM cartridge, the firmware prohibits the changing or
altering of user data already written on the tape. The firmware keeps track of the last
appendable point on the tape.
