9.3.4 Adaptive Optimization Mode
You have the choice of three modes to define the cost versus performance bias that controls
the manner in which data is moved for a given configuration as follows:
■
Performance -- The analysis parameters are biased towards moving the data to the faster
tiers and away from the slower tiers.
■
Balanced -- The analysis parameters are balanced between Performance and Cost.
■
Cost -- The analysis parameters are biased towards moving data to the slower (less costly)
tiers and away from the faster tiers.
You can use the mode parameter to differentiate between the resources that are available to
various configurations. For example, you may set the mode for a critical application’s
configuration to Performance and the mode parameter for a less important application to
Cost. The critical application’s data will then get relatively more of the higher performance
tier space than the less important application.
9.3.5 Adaptive Optimization Active
You can temporarily disable adaptive optimization by setting the Active bit to 0 (false) and re-
enable it by setting Active to 1 (true). Setting the Active bit to 0 only disables analysis and data
movement, it does not prevent System Reporter from sampling the region counters.
9.3.6 Adding an Adaptive Optimization Configuration
To add an Adaptive Optimization configuration:
1
From the Adaptive Optimization Configuration window, click Add Adaptive
Optimization Configuration.
The Add Adaptive Optimization Configuration window appears.
2
Select the system for which optimization will be enabled. The systems that are available
from the pull-down menu are added through the InServ Systems tab in the System Reporter
Policies window.
NOTE: The measurement hours selected should not exceed the retention time for
adaptive optimization samples set in the sampling policies (see
