Control Path Through a RIM or F-QIP
In a RIM- or F-QIP-based configuration, a RIM or an F-QIP 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 RIM or F-QIP can support up to eight partitions; a RIM2 can support up
to 8 partitions for a T200 or 12 partitions for a T380 or T680. Each partition
has full control of the robotics. For example, if the library contains two
partitions, a single RIM can provide the robotic control path for both
partitions.
If desired, you can configure multiple RIMs and F-QIPs as exporters for the
same partition and use your host software to export the same changer
interface over the RIMs to provide redundancy. These multiple paths
cannot be used at the same time.
If the library contains two RIMs or F-QIPs, it can be configured to use the
BlueScale Controller failover feature. This feature configures the two
controllers as a failover pair to provide a redundant control path to the
robotics (see Controller Failover on page 70 for additional information).
