The amount of usable and provisioned space that can be viewed on the GUI Dashboard page  is shown in Figure 2-10. Note:  Beginning with firmware release 1.6, the amount of  used effective capacity  is not  shown in the GUI dashboard, but it can be displayed in the CLI using the  lsarray command. The IBM FlashSystem 900 Model AE3 is supported in the IBM Compresstimator tool.
