3.2.4 Configuration Example (C) - Reserved SB Switching
Redundant configuration that is based on a spare system board (Reserved SB)

SB#3 is set as a Reserved SB for PPAR#0, PPAR#1, and PPAR#2.

If a failure occurs on the SB of a PPAR block, the system continues its operation by

disconnecting the failed SB, incorporating the spare SB, and then restarting the PPAR block.
Configuration and management costs can be reduced.

No additional software is required because the availability is based on hardware.
•
Without additional hardware or special settings, configurations and operations can be
•
achieved just by setting the firmware.
Example: Small-to-medium-sized high availability system, FT server replacement
