Structure of the library
This section defines base and expansion frames and describes the models of the TS3500
Tape Library.
The basic TS3500 Tape Library is a single storage unit known as the
base frame
(Models
L32, L52, or L53 for LTO Ultrium tape drives, or Models L22 or L23 for 3592 tape drives).
The library's scalability allows you to increase capacity by adding up to fifteen additional
storage units, called
expansion frames
(Models D32, D52, D53, and S54 for LTO Ultrium
tape drives or Models D22, D23, and S24 for 3592 tape drives). The frames join side by
side, with the base frame on the left and the expansion frame on the right. The additional
expansion frames are supported by a common cartridge accessor that requires no pass-
through mechanism. Frame Models D22, D23, D32, D52, and D53 can contain up to twelve
Ultrium tape drives or 3592 tape drives, but cannot contain a mix of both.
High-density frames, referred to hereafter as HD frames, greatly increase library capacity.
HD frame Model S54 can contain up to 1 320 Ultrium tape cartridges and HD frame Model
S24 can contain up to 1 000 IBM 3592 tape cartridges. The HD frames offer increased
capacity without increasing frame size or required floor space by using high density storage
slots for tape cartridges, referred to hereafter as HD slots.
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.
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
