16.1.3 Failure scenarios
This section describes how the failure of different components affects the
operation of our solution:
Power failure
The Tivoli Storage Manager server, the tape library, and all of the SAN fabric
components in the environment have dual redundant power supplies
connected to different power circuits. Therefore, a power failure in one circuit
does not have any effect on the operation.
IFL failure
If an IFL fails, the system remains operational, but the maximum bandwidth
available is reduced by 50%.
Router failure
If the SAN router fails, it is impossible to run LAN-free backups. In this
situation, the Tivoli Storage Manager client automatically ...
