Monitoring is much easier to use, and the system administrator can monitor all of the network
interfaces, not just the switch and administrative interfaces. The management server pushes
information out to the nodes, which releases the management server from having to trust the
node. In addition, the nodes do not have to be network-connected to each other. This means
that giving root access on one node does not mean giving root access on all nodes. The base
security setup is all done automatically at install time.

cluster building block servers, and cluster software available, visit the following links:

The CSM ships with AIX 5L itself (a 60-day Try and Buy license is shipped with AIX 5L). The
CSM client side is automatically installed and ready when you install AIX, so each system or
logical partition is cluster-ready.
The CSM V1.4 on AIX 5L and Linux introduces an optional IBM CSM High Availability
Management Server (HA MS) feature, which is designed to allow automated failover of the
CSM management server to a backup management server. In addition, sample scripts for
setting up NTP, and network tuning (AIX 5L only) configurations, and the capability to copy
files across nodes or node groups in the cluster can improve cluster ease of use and site
