Simplified ServerNet System Diagram
The ServerNet network architecture is full-duplex, packet-switched, and point-to-point
in a star configuration. It employs two independent I/O communications paths
throughout the system: the ServerNet X fabric and the ServerNet Y fabric. These dual
paths ensure that no single failure disrupts communications among the remaining
system components.
This section provides an overview of the ServerNet network in the Integrity NonStop
NS16000 systems. For further information on the ServerNet network, protocols, IP
addresses, and naming conventions, see the Introduction to Networking for Integrity
NonStop NS-Series Servers.
Simplified ServerNet System Diagram
This simplified diagram shows the ServerNet architecture in the Integrity NonStop
NS16000 system:
It shows the X and Y ServerNet fabrics with the NonStop Blade Complexes, ServerNet
adapters, and NonStop S-series I/O enclosure connections to the fabrics. Routers
within the p-switches and IOAM enclosures make up the flexible connectivity that is
inherent to the ServerNet network
