9.4 Adaptive Optimization Reports
System Reporter provides three types of Adaptive Optimization reports as follows:
■ Region IO Density -- Show the I/O access rate and distribution of data for each tier.
■ VV Tiers -- Shows the distribution of space in each VV among the tiers in absolute terms
and also as a percentage.
■ Space Moved -- Shows the space moved over a selected time interval.
You can access these reports through the System Reporter Main Menu by clicking on the
Custom Reports tab and then selecting the Adaptive Optimization report.
9.4.1 Region IO Density Report
The Region IO Density report for an Adaptive Optimization configuration, shown in Figure 9-3
on page 9.14 , shows two charts. Both charts show histograms with the X-axis (category)
illustrating the IO access rate. Each region is put into the appropriate histogram bucket on the
X-axis based on its IO access rate during the specified time period. The Y-axis (value) for the
chart on the left is the total space for the regions in the histogram bucket, and the Y-axis
(value) for the chart on the right is the total IO accesses/min for the regions in the histogram
bucket. The three CPGs corresponding to the three tiers on an Adaptive Optimization
configuration are shown with different colors on the same chart, in this case regions in red are
tier 0, regions in green are tier 1 and regions in blue are tier 2.
NOTE: See 6.4 Adaptive Optimization Reports on page 6.16 for details on
interpreting an Adaptive Optimization report.
