VERITAS Cluster Server

This application clustering solution provides application high availability for the most important applications in your data center. If it detects a fault, it takes action, recovering applications automatically. If your whole site goes down, it restarts those applications at another data center, so even during a disaster, your IT services keep running.

Cluster Name of your HA environment
Nodes Physical systems that make up the cluster
Service group Abstract container of related resources
Resource Cluster components (i.e. NICs, IPs, disk groups, volumes, mounts, processes, etc...)
Attributes Parameter values that define the resources
Dependencies Links between resources or service groups

Cluster Mgr Cluster Monitor : Log in, add clusters, change preferences
Cluster Mgr Cluster Explorer: Monitor systems, service grps, resources, attributes & dependencies
Cluster Mgr Log Desk : Monitor log messages received from engine, view GUI commands
Cluster Mgr Command Center : Build VCS commands and send to engine
LLT Low Latency transport provides fast kernel-kernel comm. & monitors network connx.
GAB Grp membership & Atomic Broadcast maintains a synch. state & monitors disk comm.
