ServerNet Cluster Overview

Network Topologies for ServerNet Clusters
Network Topologies for ServerNet Clusters
The network topology of a ServerNet cluster refers to the physical layout of
components in the network and how those components are connected together. The
network topology of a ServerNet cluster, listed in Table 1-1, determines the following:
•
The maximum number of nodes in the cluster
•
The ServerNet node numbers
•
The model number of the cluster switches supported
•
The maximum number of switches
•
The connections between switches, and between the switches and nodes
Star Topologies
The HP NonStop Cluster Switch (model 6770) supports only the three star topologies:
star, split-star, and tri-star.
Planning for the installation and management of ServerNet clusters using these
topologies is not documented in this guide. Refer to the ServerNet Cluster Manual for
more information about the 6770 switch and the star topologies.
Layered Topology
Only the 6780 switch is supported for the layered topology. Table 1-2 describes the
characteristics of the layered topology.
To support the layered topology, the NonStop S-series server requires the software
listed in Software Requirements for NonStop S-Series Servers on page 1-8.
Figure 1-1 shows a diagram of a ServerNet cluster uses the layered topology. In this
example the cluster consists of two zones and two layers and supports up to 32 nodes.
Note. ServerNet clusters that use the layered topology do not support the 6770 switch
components, including the ServerNet II Switch, AC transfer switch, and UPS, in the same
external fabric with the 6780 switches. However, the 6770 switches and 6780 switches can be
installed on different external fabrics to facilitate migration to the layered topology.
