Cartridge Movement
The movement of cartridges into the Elastic Capacity area is automated by the
library firmware. The movement of cartridges from the Elastic Capacity area is not
automated by the library firmware - that movement occurs when requested by the
application, GUI, or CLI
TS7700 backend switch support
A TS4500 tape library can be connected to a TS7700 system using two 16 Gb fibre
channel switches. The switches can be installed in the bottom of the TS4500 frame,
or in a TR1 rack mounted above the TS4500.
Mixed drives in frames
You can mix some drives in a TS4500 tape library frame.
Table 12 presents a matrix of drive combinations that are compatible in the
physical frames of the TS4500 tape library.
Note: No drives are installed in the storage-only frames (models S25 and S55).

Mixed media in drives
Tape drives installed in the TS4500 tape library can read and write multiple tape
cartridges; however, only certain combinations of drives and media are supported.
Not all cartridges that are supported by the TS4500 tape library are compatible
with all drives. LTO cartridges are not supported by 3592 tape drives, and 3592
tape cartridges are not supported by LTO drives.
Table 13 on page 33 presents a matrix of cartridges that are compatible with the
LTO tape drives that are supported by the TS4500 tape library.
Table 14 on page 34 presents a matrix of cartridges that are compatible with the
3592 tape drives that are supported by the TS4500 tape library.
