Introduction and considerations
VERITAS Cluster Server (VCS), similar to Sun Cluster, provides an integrated cluster framework for controlling and monitoring services for high availability. The unit of failover in VCS is a service group. A service group can be used to define a collection of resources such as disks, IP addresses, and processes.
Configuring VERITAS Cluster Server is similar to configuring the Sun Cluster as discussed above. A typical configuration, shown in Figure 12-8, includes two nodes interconnected by private networks and a shared disk.
