Exporting Controllers - Spectra Logic Spectra T950V User Manual

Chapter 1 — Library Overview

Exporting Controllers

Either a direct‐attached LTO drive or a RIM2 is required to provide the
control path for the library's robotics. When configuring a storage
partition, the device you select to provide the robotic control path is
referred to as the "exporting controller" for the partition.
The controller is the bridge between an external Fibre Channel or SAS
connection from the host and the internal interface used by the library. It
provides the control path for the media changer commands sent from the
host to the library. The controller relays the commands to the RCM, which
processes the commands and uses them to control the robotics in the
library.
A minimum of one controller is required to connect the library's robotics to
the host network. To learn more about the role the controller plays in the
library, see Robotic Controller Connectivity on page 60.

 An LTO tape drive can only provide the control path for one
Notes:
partition. A RIM2 can provide the robotic control path for up
to 16 partitions.
 The maximum number of exporting controllers (drives and
RIMs) supported by the library is six.
 A TS11xx technology drive cannot provide the robotic
control path. TS11xx technology partitions must use a RIM2.
 RIM2s can be configured for controller failover.
 If desired, you can configure multiple exporting controllers
(drives or RIM2s) for a partition, and export the same changer
interface over the drives to provide redundancy, as long as
your backup software can support this. These multiple paths
cannot be used at the same time.
