I/O Adapter Module (IOAM) Enclosure and I/O
Adapters
This illustration shows the front and rear of the IOAM enclosure and details:
Because the IOAM enclosure contains two modules, one IOAM enclosure can provide
fault-tolerant paths. However, the paths must be configured through both modules. For
example, you could configure these paths through four FCSAs:
These paths all exist within the same group. But they are divided between two
modules, so the configuration is fault-tolerant. For additional information, see Fibre
Channel Devices on page 4-19.
