a. Fast
— Sets a fast response time. This setting is optimal for most workloads where low latency
response to an increase in processor demand is a requirement.
b. Slow
Sets a slow response time. This setting is optimal for workloads where a longer latency
response to an increase in processing demand is an acceptable trade off for reduced power
consumption.

Collaborative Power Control
When
Power Profile
is set to
Custom
, use this option to enable or disable collaborative power control.
For operating systems that support the Processor Clocking Control (PCC) interface, enabling
collaborative power control configures the operating system to request processor frequency changes,
even when the
Power Regulator
option is set to
Dynamic Power Savings Mode
on the server. 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 on system operation.
