4. There are three clone configurations, describe on the following.

x Snapshot space:
Figure 5.6.5
This setting is the ratio of source VD and snapshot space. The default ratio is 2
to 1. It means when the clone process is starting, the system will automatically
use the free RG space to create a snapshot space which capacity is double the
source VD.
x Threshold: (The setting will be effective after enabling schedule clone)
Figure 5.6.6
The threshold setting will monitor the usage amount of snapshot space. When
the used snapshot space achieves its threshold, system will automatically take a
clone snapshot and start VD clone process. The purpose of threshold could
prevent the incremental copy fail immediately when running out of snapshot
space.
For example, the default threshold is 50%. The system will check the snapshot
space every hour. When the snapshot space is used over 50%, the system will
synchronize the source VD and target VD automatically. Next time, when the
