Getting the most from PowerMAN
Baseline existing environment
PowerMAN will work best if the existing environment is measured before any power management is
attempted. We therefore recommend that the software is used for passive monitoring only during the
first few weeks of operation. This passive process is completely transparent to users.
After a consistent pattern has emerged this information may then be used to inform decisions
about which power management strategy to use and then quantify the effect of the chosen strategy.
After you have implemented the energy reduction strategy it can be very useful to refer back to the data previously logged to measure
progress and identify areas for possible further improvement.
The software offers many different ways to manage power effectively. The following sections explain
best practices and provide some useful tips on getting the most from PowerMAN.
Typical deployment phases
A typical PowerMAN deployment is divided into three distinct phases:
- An initial period of passive monitoring. This allows a baseline usage profile to be established
- Deployment of an active power policy. This is designed to reduce energy from the established baseline. Often the specific settings used are chosen based upon both the results of the monitoring phase and existing knowledge about the usage pattern and user requirements. This policy may be implemented using a combination of Idle or Schedule-based power management.
- A post deployment monitoring phase. In this phase the power policy is monitored and areas for possible further improvement may be identified and implemented
