HP Insight Cluster Management Utility - Manual (Page 28)

attached to the HP Insight CMU management server that is running the HP Insight CMU software
at a given time. The HP Insight CMU management cluster is known on the site network by the
address IP0, and on the compute network by the address IP1. IP0 and IP1 are the only addresses
HP Insight CMU recognizes. If that server fails, then IP0 and IP1 migrate to the other server. The
two servers each have one IP address per network (IP2, IP3, IP4, IP5). The two servers are connected
to shared storage which hosts the HP Insight CMU directory. This configuration is perceived as a
“classic” HP Insight CMU configuration with a single management server by the compute nodes,
and from the user's point of view.
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.
