In Figure 81 on page 234 you can see on the left a regular volume with three snapshots and on the
right, a regular volume with one SmartClone volume, one clone point, and two shared snapshots.

Example scenarios for using SmartClone volumes

The following examples are just a few of the most typical scenarios for using SmartClone volumes.

Deploy multiple virtual or boot-from-SAN servers

You can save significant space in environments with multiple virtual or boot-from-SAN servers that use
the same base operating system. A server's operating system takes up considerable storage but does
not change frequently. You can create a master image of the operating system on a volume and
prepare it for duplication. Then you can create large quantities of SmartClone volumes from that
master image without using additional storage capacity. Each SmartClone volume you create from
the master image is a full read/write version of the operating system and has all the same management
features as a regular HP StorageWorks P4000 SAN Solution volume.
Scenario: Computer training lab
You run a computer lab for a technical training company. You routinely set up training environments
for classes in programming languages, database development, web design, and other applications.
The classes are anywhere from 2 days to 1 week long, and your lab can accommodate 75 students.

Shared snapshots occur when a clone point is created from a newer snapshot that
has older snapshots below it in the tree. Shared snapshots can be deleted. In
81 on page 234, the snapshots Volume_1_SS_1 and Volume_1_SS_2 are shared
snapshots.
