HP ProLiant DL160 G5 Storage-Server - Manual (Page 130)

• 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.

Sequence of events for cluster resources
The sequence of events in the diagram includes:
1. Physical disks are combined into RAID arrays and LUNs.
2. LUNS are designated as basic disks, formatted, and assigned a drive letter via Disk Manager.
