Cluster Concepts; Sequence Of Events For Cluster Resources; Cluster Concepts Diagram - HP PROLIANT ML110 G5 User Manual

• Storing the most current version of the cluster database
• Guaranteeing that only one set of active communicating nodes is allowed to operate as a cluster

Cluster concepts

Figure 40 illustrates a typical cluster configuration with the corresponding storage elements. The
diagram progresses from the physical disks to the file shares, showing the relationship between both
the cluster elements and the physical devices underlying them. While the diagram only illustrates two
nodes, the same concepts apply for multi-node deployments.
