• In order to support mixed media in an HD library with dual accessors, service bay B
must be a model Dxx frame. This configuration requires feature code 1697, which
ensures that the service bays provide both LTO and 3592 HD test slots.
• Expansion frame Model D32 cannot be used as service bay B.

This section describes high density technology in the TS3500 Tape Library.
The TS3500 Tape Library offers high-density, storage-only frame models (HD frames)
designed to greatly increase storage capacity without increasing frame size or required floor
space. The new HD frames (Model S24 for 3592 tape cartridges and Model S54 for LTO
Ultrium tape cartridges) contain HD storage slots.
HD slots contain tape cartridges in a tiered architecture. The cartridge immediately
accessible in the HD slot is a Tier 1 cartridge. Behind that is Tier 2 and so on. The maximum
tier in an LTO Ultirum (Model S54) HD slot is Tier 5. The maximum tier in a 3592 (Model
S24) HD slot is Tier 4 because the 3592 tape cartridge is slightly longer than the LTO
Ultrium cartridge. The single-deep slots on the door side of HD frames are referred to as
Tier 0 slots. On the left, Figure 1 shows the inside of an HD frame from the side. On the
right, Figure 1 shows a top-down view of one row of an HD frame with cartridges in Tiers 0
(door side), 1, 2, and 3.
