Choosing a Container Type
Different applications may have different storage requirements. You probably want to
configure more than one kind of container within your subsystem.
In choosing a container, you choose between independent disks (JBODs) or one of
several storageset types, as shown in Figure 2–4. The independent disks and the
selected storageset may also be partitioned.
The storagesets implement RAID (Redundant Array of Independent Disks)
technology. Consequently, they all share one important feature: each storageset,
whether it contains two disk drives or ten, looks like one large, virtual disk drive to the
host.
