The Fast setting is optimal for most workloads that require a low latency response to an increase in processor demand. The slow setting is optimal for some workloads where a longer latency response to increases in processing demand is an acceptable tradeoff for reduced power consumption. Depending on the processor workload, selecting this option may negatively impact performance. Collaborative Power Control (G7 servers) For Operating Systems that support the Processor Clocking Control (PCC) Interface, enabling this option allows the Operating System to request processor frequency changes even when the server has the Power Regulator option configured for Dynamic Power Savings Mode. For Operating Systems that do not support the PCC Interface or when the Power Regulator Mode is not configured for Dynamic Power Savings Mode, this option has no impact to system operation. • Enabled (Default) RBSU menu (HP ProLiant G7 servers or server blades) 42
