Cluster concepts
Figure 42 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.
