addition, HD frames can support shuttle stations that enable connections between
multiple TS3500 Tape Library strings. For more information, see “Structure of the
shuttle complex” on page 15.
Note: Base frame models L22, L23, L52, L53, and L32 are referred to hereafter as
base frames , unless model-specific information is discussed. Expansion frame
models D22, D23, D52, D53, D32, S24, and S54 are referred to hereafter as expansion
frames , unless model-specific information is discussed.
The TS3500 Tape Library features an optional second cartridge accessor. If you
order dual accessors, two frames that are used as
service bays are required. Service
bay A is known as Model HA1 and service bay B is a Model D23, D22, D52, D53,
S24, or S54 frame. For more information, see “Dual accessors and service bays” on
page 7.
Note: 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.
For bulk media handling, the TS3500 Tape Library supports four I/O stations in
newly purchased Models D23 and D53 frames. The D-frame with I/O installed is
comprised of four independently accessible I/O station doors with a total of 64
slots (16 in each I/O station door). Additionally, two LED indicators are provided
for each I/O station in a D-frame in order to indicate if the I/O station is empty or
full and if the I/O station door is locked or unlocked. This plant feature reduces
the frame storage slot capacity by 160 for a Model D23 and by 176 for a Model
D53. The I/O stations increase the maximum library I/O slot capacity from 32 to
224. The multiple I/O stations can double the maximum insert and eject
throughput since both accessors can be used. The D23 and D53 models remain
compatible with existing Models L22, L32, L52, D22, D32, and D52.
The models of the TS3500 Tape Library vary depending on the type of media they
contain and whether the frame is a service bay, a base frame, or an expansion
frame. Table 5 lists each frame and its characteristics.
