Multi-server setup is supported using the iLO scripting interface with batch processes, the Rapid Deployment Pack, or HP Insight Power Manager. Power Regulator modes System administrators can configure Power Regulator for

Dynamic Power Savings mode can be supported whether or not an operating system supports Intel's Demand Based Switching or AMD's PowerNow and regardless of which operating system the server is running. Current HP ProLiant servers enable HP Dynamic Power Savings mode by default, so
