ServerNet Cluster 6780 Planning and Installation Guide—527301-005
xv
About This Guide
This guide describes installing or migrating to ServerNet clusters using 6780 switches
and the layered topology. It assumes that you are familiar with HP NonStop S-series
or NS-Series servers, the ServerNet protocol, and networking fundamentals. If you are
not familiar with these concepts, refer to the NonStop S-Series Server Description
Manual. This table describes the sections and appendixes of this guide.
Section Title This section...
1 ServerNet Cluster
Overview
Introduces the ServerNet Cluster product. It
describes concepts that are essential to
understanding the operation of a ServerNet cluster.
2 ServerNet Cluster
Hardware Description
Describes the ServerNet cluster hardware, including
the 6780 switches.
3 Planning for Installation
and Migration
Describes how to plan the installation of ServerNet
cluster hardware and software.
4 Preparing a System for
Installation or Migration
Describes how to prepare a system before installing
a new ServerNet cluster that uses the layered
topology, or before migrating a current ServerNet
cluster to the layered topology.
5 Installing 6780 Switches
Describes how to install or migrate to a ServerNet
cluster that uses the layered topology.
6 Connecting the Fiber-
Optic Cables
Describes how to connect the fiber-optic cables
between 6780 switches and nodes or other
switches.
7 Configuring Expand-
Over-ServerNet Lines
Describes how to configure Expand lines using
either SCF or OSM.
8 Checking Operations
Describes how to check that a ServerNet cluster is
operating properly.
9 Changing a ServerNet
Cluster
Describes how to change the size of an already-
installed ServerNet cluster (without changing the
topology).
10 Troubleshooting
Describes how to troubleshoot problems that might
occur during installation.
11 Starting and Stopping
ServerNet Cluster
Processes and
Subsystems
Describes how to start and stop processes required
for the ServerNet cluster.
Appendix
A Part Numbers
Lists part numbers and service categories for 6780
switch hardware components.
B Blank Planning Forms
Contains blank copies of Planning Forms. Also
contains illustrations showing sample connections in
the layered topology.
