Table 4. TS3500 Tape Library configurations (continued)
A library including these
models
|
| | |
L32, D32, S54, and SC1
|
|
| | | L2x, D2x, S24, and SC1
|
| Notes:
| 1. In order to support code level 9500 or higher, all node cards in the library must be xx3-equivalent node cards.
| For xx2 models, this requires a xx3 model conversion OR the enhanced node card(s) feature (FC 1700 or 1701).
| 2. In order to increase the maximum number of cartridges to more than 6 887, or to support a shuttle complex,
| logical libraries must use LTO Ultrium 4, 3592 E05, or later tape drives as control path drives. In order to
| support more than 6 887 cartridges, Ultrium 4 control path drives require a minimum code level of 97F0. For
|
logical libraries with shuttle stations assigned, Ultrium 4 control path drives require a minimum code level of
|
A480 and Ultrium 5 control path drives require a minimum code level of B170.
|
3. The maximum native capacity figures are based on library configurations with high density (HD) frames and all
|
Ultrium 6 or 3592 E07 tape drives. In addition, the figures for libraries with Model SC1 (shuttle connection) are
based on the maximum shuttle complex configuration.
|
4. In order to support Ultrium 6 tape drives, libraries with an L32 frame require enhanced grippers (FC 2205 or
|
2304).

For detailed information regarding tape drives supported by the TS3500 Tape
Library, and the data rate and capacity for these drives, see "Supported tape
drives" on page 17. For information regarding supported tape media, refer to
"Supported tape cartridges" on page 25. For details regarding frame models and
frame capacity, see "Structure of the library." For information about the shuttle
complex and Model SC1, refer to "Structure of the shuttle complex" on page 15.
This topic 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 15 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 12 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. For more information, see "High density technology" on page 9. In
