Increasing Capacity; Capacity Expansion Feature For Model L32; Mixing I/O Stations Among Frames Of The Ts3500 Tape Library - IBM TS3500 Introduction And Planning Manual

Note: The 64 additional I/O slots features (feature codes 1655 and 1656) are not
supported on libraries with mixed media. In order to use this feature, the library
must use all Ultrium media or all 3952 media, not a mixture of both.
Table 14 shows how I/O stations can be mixed among frames.
For additional information, also refer to "Virtual I/O slots" on page 47.

Increasing capacity

This section introduces information about capacity configurations for frames of the
TS3500 Tape Library.
Depending on whether you have the Capacity Expansion feature, Capacity On
Demand feature, or High Density Capacity on Demand feature installed in your
library, different capacity configurations exist for the frames.
The sections that follow describe each feature.

Capacity expansion feature for Model L32

The Capacity Expansion feature (feature code 1603) is a license key that lets you
enable the storage slots inside the front door of Model L32 of the TS3500 Tape
Library. With the Capacity Expansion feature installed, the library offers 140
additional slots for Ultrium tape cartridges in the Model L32 if the second I/O
station is not present and 88 additional slots if the second I/O station is present.
The Capacity Expansion feature is required when you add one or more expansion
frames to the base frame.

Notes:
1. The 3592 I/O station for Model L32 is included with feature code 1608.
2. For the 64 additional I/O slots option, feature code 1451 must be installed as a
prerequisite, then either feature code 1655 for LTO Ultrium media, or feature code 1656
for 3592 media. When expanding an installed library, feature codes 1655 and 1656
assume the D-frame is installed at the end of the library string ("end of the library
string" refers to the very last frame in a single accessor library or the last frame before
SBB in HA libraries). If the customer prefers the D-frame to be installed elsewhere in
the string, the Service Representative must obtain a "Services Contract" to uninstall
additional frames as necessary to accommodate the customer's request.
3. Mixed media is not allowed in libraries with D-frame I/O slots. All cartridges must be
either LTO Ultrium or 3592.
4. A maximum of three D-frames with I/O slots can be installed per library.
