Cluster Interconnect
Compaq ProLiant Clusters for SCO UnixWare 7 with the ML330 use a
dedicated, private Ethernet interconnect network. The Ethernet interconnect
uses the embedded NICs and an Ethernet crossover cable to connect the two
nodes.
The cluster nodes use the interconnect data path to support the single-system
image capabilities of the cluster, including:
I Cross-node mirroring
I Cluster-wide file system
I Cluster-wide process management, migration, and load balancing
I Cluster-wide networking and Cluster Virtual IP (CVIP)
I Cluster-wide system administration and management
Ethernet Crossover Cable
The Ethernet crossover cable provides the node-to-node communication data
path for the cluster.
Cluster Integrity Serial Cable
The CI serial cable is required to prevent a condition known as split-brain.
Split-brain is a condition where both nodes in a two-node cluster think they are
the root node and both try to operate as the root node. Since the active root
node mounts the root file system and runs several critical cluster-wide
functions, two nodes trying to behave as the root node is undesirable.
NOTE: The CI serial cable may be referred to as the split-brain avoidance (SBA) serial
cable in UnixWare software and documentation.

Compaq Insight Manager Overview
Compaq Insight Manager is the Compaq console-based application for
managing networked devices. Compaq Insight Manager provides intelligent
monitoring and alerting capabilities for the critical systems in a distributed
enterprise.
Compaq Insight Manager consists of a console application and a set of server-
or client-based management data collection agents. Key subsystems are
designed to make system health, configuration, and performance data available
to the agent software. The agents act upon data by initiating SNMP alarms in
the event of faults and by providing updated management information.
Compaq Insight Manager is located on the Compaq Management CD. Install
Compaq Insight Manager on a Win32 desktop computer using the instructions
provided on the CD. The nodes within the cluster appear to Compaq Insight
Manager as separate UnixWare 7 systems.
Refer to the Compaq Insight Manager Users Guide included on the Compaq
Management CD for more information on installing Compaq Insight Manager.
