Mixed Media
HP Tape Libraries have a mixed media feature that allows the use of two
different drive technologies in the same library. (See page -v for a list of
libraries and the drive technologies they support.)
NOTE Supported use models are described in detail in the Mixed Media White
Paper for the Network Administrator. This document is available from
www.hp.com/support/modularlibrary for tape library models 2/20, 4/40,
and 6/60, and from www.hp.com/support/tapelibrary for model 12/140.
General considerations when using mixed media:
• Upgrade kits are available from HP for Ultrium tape drives,
magazines, and tape cartridges.
• The same type of drive per level of the library is the only mixed media
configuration supported by HP. This excludes tape library model 2/20
from a mixed media use model at this time.
• HP recommends maintaining the same magazine ratio as the drive
ratio.
• In order to provide full mailslot support in a mixed media library, one
magazine is required for each drive type for a total of 10 mailslots.
Only DLT tapes can be used in a DLT magazine, and only Ultrium
tapes can be used in an Ultrium magazine.
• HP Library & Tape Tools version 2.2 or greater is required for
diagnostic support (see page 1-5).
