System Reporter 2.8

NOTE: The measurement hours selected should not exceed the retention time for adaptive optimization samples set in the sampling policies (see 7.2.2 Editing Sampling Policies on page 7.4).

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 reenable 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:

1From the Adaptive Optimization Configuration window, click Add Adaptive Optimization Configuration.

The Add Adaptive Optimization Configuration window appears.

2Select 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.
