Viewing Trending Information for Storage Capacity
The management server can display trending information in its reports. For example, you can
configure Capacity Manager to display trending information for the next week. This information can
give you an indication of an element's future capacity need based on its past capacity utilization.
Keep in mind the following:
• An element's capacity can drastically change in the future. Please keep in mind the data trends
are just assumptions and should not be treated as fact.
• Trending requires at least two sets of data gathered within the frequency specified.
To view trending information:

information for five frequency intervals, such as five weeks if weeks was selected from the
Frequency
drop-down menu.
