Term Definition Clone point The snapshot from which the SmartClone volumes are created. The clone point cannot be deleted. In Figure 81 on page 234, the snapshot Volume_1_SS_3 is the clone point. Shared snapshot 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 Figure 81 on page 234, the snapshots Volume_1_SS_1 and Volume_1_SS_2 are shared snapshots. Map view Tab that displays the relationships between clone points and SmartClone volumes. See the map view in Figure 93 on page 249 and Figure 94 on page 250. 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. 1. Regular volumes and snapshots 2. SmartClone volumes, with clone points and shared snapshots Figure 81 How SmartClone volumes, clone points, and shared snapshots appear in the CMC . 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. 234 SmartClone volumes
