Space Utilization
The Space Utilization chart displays how space is consumed over a period of time. The
topmost line refers to the total space occupied by a volume and all its snapshots together.
The middle line indicates total volume space occupied and is also extrapolated (dotted
line) to show the predicted growth. The bottom line is the space occupied by the file
system (this is applicable for NAS Volumes only. In the above figure you can see that the
volume selected is a SAN volume so the bottom line lies on the x-axis). The user can use
the sliding window in the top chart to get a more detailed view in the bottom chart of how
the space was consumed over a period of time. The size of the sliding window is also
adjustable by the user.
