   • If you have uploaded a purchased license, the capacity information is displayed based on the license type.
   • When the ratio of the used capacity to the total capacity exceeds 80%, the progress bar is in orange, indicating that the capacity is about to be used up.
   • Storage system capacity conversion: 1 PB = 1,024 TB, 1 TB = 1,024 GB, 1 GB = 1,024 MB, 1 MB = 1,024 KB, and 1 KB = 1,024 bytes

6. In the Top 5 Storage Pool Capacity Trend area, view the capacity trend of the top 5 storage pools sorted by capacity usage in descending order.
   

   You can click More in the upper right corner of the Top 5 Storage Pool Capacity Trend area to view details about existing storage pools of the storage system on the Storage Pool page.
