When you purchase your library, you may specify that the Capacity Expansion
feature be installed at the factory, or you may order the feature later and have your
IBM Service Representative install it. To order the Capacity Expansion feature,
contact your IBM Sales Representative.
To determine the quantity of LTO Ultrium tape cartridges and 3592 tape cartridges
that the library supports, see Chapter 7, “Frame capacity,” on page 211.
Intermediate, Full, and Capacity On Demand features for
Models L22, L23, L52, and L53
In the TS3500 Tape Library, the initial (entry) capacity of a Model L22 or Model
L23 frame is enabled to use 58 cartridge slots for 3592 tape cartridges. If you add
the Intermediate Capacity or Full Capacity features, you can enable additional
storage elements in the Model L22 or Model L23 to increase the available capacity
to 117 cartridge slots, or from 199 to 260 cartridge slots (depending on the features
that you order).
The initial capacity of a Model L52 or Model L53 frame is enabled to use 64
cartridge slots for LTO Ultrium tape cartridges. If you add the Intermediate
Capacity or Full Capacity features, you can enable additional storage elements in
the Model L52 or Model L53 to increase the available capacity to 129 cartridge
slots, or from 219 to 287 cartridge slots (depending on the features that you order).
The Intermediate Capacity feature is available through an IBM plant site as feature
code 1641 and through the field as feature code 1643.
The Full Capacity feature is available through an IBM plant site as feature code
1642 and through the field as feature code 1644. This feature is required to add a
16-slot I/O station. The Intermediate Capacity feature is a prerequisite to the Full
Capacity feature. The Full Capacity feature is required when you add one or more
expansion frames to a base frame.
Capacity features that are available through the field are known as Capacity On
Demand.
To determine the quantity of LTO Ultrium tape cartridges and 3592 tape cartridges
that the library supports, see Chapter 7, “Frame capacity,” on page 211.
High Density Capacity On Demand
This section describes the High Density Capacity on Demand features for the
TS3500 Tape Library.
The HD Capacity on Demand feature codes provides a license key that let you
enable additional storage slots in HD frames.
In the TS3500 Tape Library, the physical capacity, or total storage slots, is
comprised of licensed and unlicensed capacity. When the number of assigned
cartridges within a library reaches the licensed capacity, additional inserted
cartridges are not assignable to a logical library until one of the following actions
occurs:
v
A cartridge is removed
v
A CoD feature is purchased
v
Additional slots or frames are added to the library
