Modules
Scalar i500 libraries are modular, and you can increase the size at any
time. The three base systems for the Scalar i500 library are as follows:
• The 5U library, consisting of a control module
• The 14U library, consisting of a 5U control module and a 9U
expansion module
• The 23U library, consisting of a 5U control module and two 9U
expansion modules
These configurations can be scaled up by adding 9U expansion modules
to a maximum rack height of 41U. Expansion modules provide additional
capacity as your storage and tape drive requirements change. See
Figure
4
on page 15 for an illustration of library scalability. For information on
installing, removing, and replacing modules, see
Installing, Removing,
and Replacing
on page 170.
Each module has a specific number of fixed storage slots, I/E station
slots, and tape drive slots available. See
Library Capacity
on page 365 for
the number of slots available for each library configurations.
Control Module
1
The control module is required in any Scalar i500 library configuration.
The control module contains the robotic controls, library control blade
(LCB), and touch screen display. The control module also contains an
import/export (I/E) station, fixed storage slots, tape drives, and at least
one power supply.
Expansion Modules
1
Expansion modules are supplementary modules that can be stacked
above or below the control module. Each expansion module contains
fixed storage slots, tape drive slots, and power supply slots.The I/E
stations on expansion modules are included and may be configured as
storage. Expansion modules also contain bays for optional Fibre Channel
Note:
Slot counts in this
User’s Guide
do not include
five inaccessible
slots in the bottom row of any library configuration. For more
information about these slots, see
Unused Slots
on page 131
