Example System ServerNet Pathways
The IOAM enclosures can reside in the same or different cabinets with MMF fiber-optic
cables carrying the ServerNet communications between the IOAM enclosures and the
p-switches. ServerNet routing for the Y fabric is the same through the Y fabric peer p-
switch and ServerNet switch boards in the IOAM enclosures and the IOMF 2 CRUs in
the NonStop S-series I/O enclosures.
If a cable, connection, router, or other failure occurs, only the system resources that
are downstream of the failure on the same fabric are affected. Because of the
redundant ServerNet architecture, communications takes the alternate path on the
other fabric to the peer resources. For example, if the ServerNet switch board for the Y
fabric fails, the downstream adapters and the storage or communications that connect
to the failed switch board are unavailable to the system. The system then switches the
communication to the X fabric where all devices are available. After the failed FRU is
replaced, the affected fabric and resources connected to it are again available to the
system.
