The Oracle Enterprise Manager for Flash Storage Systems provides two storage usage reports: a Storage Usage by LUN report, and a Storage Usage for LUN by QoS report.
A graph of the top 10 LUNs show the percentage of total space and the percentage of allocated space on the selected Oracle FS System.
The Storage Usage for LUN by QoS report consists of three pie charts that show the percentage of storage usage by LUNs that have priority, data access, or I/O bias Quality of Service (QoS) attributes.
