HP Insight Cluster Management Utility - Manual (Page 24)

The next figure shows a “classic” HP Insight CMU cluster with one HP Insight CMU management
server and compute nodes connected directly to the site network. A unique IP address IP0 is used
for compute node management and site network access.
The next figure shows the corresponding configuration with two HP Insight CMU management
servers running HP Insight CMU software in active or standby mode under control of HA software.
The address IP0 is attached to the server running the HP Insight CMU software. This is the unique
address HP Insight CMU recognizes. Each HP Insight CMU management server has its own IP
address on the site network, IP2 and IP 3 respectively, unknown to HP Insight CMU.
