IGH VAILABILITY
In high‐availability enterprise environments, keeping the library operating
even in the event of a network connection failure or component failure is
extremely important. The following sections describe the high‐availability
features of the TFinity library.

Redundant Connectivity

In a high‐availability environment, the ability to maintain communications
between the host systems and the library and its drives in the event of a
connection failure is essential.

ONFIGURATIONS
BlueScale Controller Failover feature to provide redundant
connectivity to the media changer functionality of the library. See
Configure Controller Failover on page 128 for information about
configuring controller failover.
Updating the BlueScale Software and Library Firmware on page 434
export the same changer interface to provide redundancy, or to send
multiple moves to the partition which are analyzed by MediaIQ so that
the moves are processed in the most efficient way.
attached Fibre Channel drives in the library can use failover software to
provide redundant connectivity through the two Fibre Channel ports
on each full‐height drive.
