Project is cancelled;
space is freed up
In most organizations, projects come and go. If a
project is cancelled, or significantly scaled back,
the storage needs for the project may be much less.
In these cases, it makes sense to shrink
the volume.
Application growth is
slower than expected
Sometimes, the growth estimate for a volume
turns out to be too high. If the data is not growing
as fast as anticipated, it may be prudent to shrink
the volume so that the space on the SAN can be
better utilized by volumes that are growing more
quickly.
Volumes created as
Full Provisioned
while using SAN/iQ
versions earlier than
7.0 may not take
advantage of the
Thin Provisioning
2.0 features found in
SAN/iQ 7.0.
Changing these volumes to Thin Provisioning in
SAN/iQ 7.0 may not regain space as anticipated.
