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.
