Using the Storage Summary Plugin
The Storage Summary plugin displays a bar chart that shows detailed information about disk space on a Storage Center and a graph
that shows the past four weeks of disk space usage for a Storage Center.
Figure 31. Storage Summary Plugin
Use this graph to compare the amount of used disk space to the amount of available disk space on a Storage Center. In addition, use
this graph to compare the used disk space to the alert threshold for disk space. An alarm occurs if the amount of used disk space
reaches the alert threshold value.
Storage Summary Bar Chart
Use the bar chart to view available disk space, allocated disk space, used disk space, free disk space, and Savings vs RAID 10. In
addition, the amount of congured disk space and oversubscribed disk space is displayed below the bar chart.
