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
(FC) Input/Output (I/O) blades, which provide FC connections for FC
drives in the library.
If an expansion module is used only for storage and does not contain tape
drives or FC I/O blades, it does not need a separate power supply. All
power is derived from the control module.
Stackability 1
The maximum rack height of the library is 41U, which consists of a 5U
control module and four 9U expansion modules. Figure 4
illustrates the
stackability of the library and the recommended library configurations.
