so on).
Coarse – Provides a compact level of detail (for example, 1, 8, 64, 512 IO/(GiB*min), and

Creating an AO Configurations Space Moved Report
The AO Space Moved report displays the space moved over the selected time interval for each
AO configuration. The space moved between tiers represents a performance overhead for Adaptive
Optimization as it takes system resources and disk bandwidth to move data between tiers.
The report displays the space moved between tiers. The report uses stacked bar charts to display
the report data. The X-axis (category) represents an AO configuration with space moves between
tiers shown in different colors. The Y-axis (value) indicates the amount of space moved between
the tiers.
