2.1 Policy Advisor for Dynamic Optimization
The 3PAR Policy Advisor script for Dynamic Optimization analyzes how your virtual volumes
use physical disk space and recommends actions to improve the performance of your InServ
Storage Server. The Policy Advisor uses CLI commands that are part of the 3PAR Dynamic
Optimization feature which allows you to improve the performance of virtual volumes without
interrupting access to the virtual volumes. You can change the parameters, RAID levels, set
sizes, and disk filters for virtual volumes with the Policy Advisor. You must have a 3PAR
Dynamic Optimization license to use the 3PAR Dynamic Optimization feature and the Policy
Advisor script.
The Dynamic Optimization feature enables you to non-disruptively re-layout virtual volumes
and promotes system optimization through improved use of all physical resources present in
the system. In addition, Dynamic Optimization enables you to alter the service levels associated
with a given volume by changing volume parameters.
For example, when an InServ Storage Server is upgraded by adding nodes, cages, or physical
disks, the initial volume and logical disk layouts may no longer be optimal for the new system
configuration. Dynamic Optimization enables you to re-layout volumes with entirely new
parameters to take advantage of the current system configuration.
