Redundant Controller
10.1 Operation Theory
Sample topologies using redundant controllers can be found in the Hardware
Manual that came with your controller or subsystem. The proceeding
discussions will focus on the theories and the firmware configuration of a
redundant controller system.
Because I/O interfaces have increasing demands on signal quality,
combining controllers using the cabling method may not all work well.
Depending on enclosure design, signal paths for communications may have
been strung between controllers over a common backplane. The controllers
or subsystems, like Infortrend’s EonStor series, may come with preset IDs
and channel mode that require no further configuration.
Users who are familiar with the practice of redundant controller
configuration, please jump to section "
