Chapter 2 — Architecture Overview
Figure 19 shows an example of a partition with two Fibre Channel drives
providing the robotic control path. LUN 1 on the drives provides the
robotic control path over which the commands to the robotics are received
from the host.

Control Path Through a RIM2
In a RIM2‐based configuration, a RIM2 is the exporting controller for the
partition. This controller provides the bridge between the external Fibre
Channel interface from the host and the internal interface used by the
library to communicate with the robotics.
A RIM2 can support up to 16 partitions. Each partition has full control of
the robotics. For example, if the library contains two partitions, a single
RIM2 can provide the robotic control path for both partitions.
