AHV推荐的CPU性能设置是什么？我很好奇AHV是否能够与Intel节流局有联系，或者最好一直全速运行。

CPU功率选项是：
每瓦DAPC的性能
每瓦操作系统的性能
表现

雅典卫城管理程序201602173 Dell XC730XD节点，带2 x Xeon E5-2630 v3 @ 2.40GHz

DELL主动功率控制（DAPC）模式允许BIOS管理处理器功率状态，以便在所有利用水平和工作负载类型上实现性能/瓦特，同时仍满足性能要求。

在OS（基于需求的电源管理（DBPM）模式）中，操作系统（OS）控制处理器的电源管理。

在最大性能模式下，处理器一直以最高频率运行。

  • 每瓦优化的性能（DAPC）此模式允许BIOS管理处理器功率状态，以便在所有利用水平和工作负载类型上实现性能/瓦特，同时仍然满足性能要求。BIOS还可以在此模式下管理系统电源封盖。

  • 在此模式下，每瓦优化（OS）的性能，CPU电源管理字段设置为OS DBPM。这意味着操作系统（OS）控制处理器的电源管理。主要控件是处理器频率或性能状态（P-states，P0，P1…PN）和处理器时钟节流（T型，T0，T0，T1…TN）。OS根据节点管理器输入和处理器利用率来修改电源状态以实现最佳的操作性性能。

  • 在此模式下的性能，CPU电源管理字段设置为性能，并允许BIOS为处理器编写最大性能状态。

\nJon Kohler here, I'd be happy to sync up with you locally in Den or via Webex on this and the other thread you've got open if you'd like, always happy to chat.

\nThe CPU power options are:
\nPerformance Per Watt DAPC
\nPerformance Per Watt OS

\nThe Dell Active Power Control (DAPC) mode allows the BIOS to manage the processor power states in order to achieve Performance\/Watt maximized at all utilization levels and workload types while still meeting performance requirements.

\nIn the OS (Demand Based Power Management (DBPM) mode, the operating system (OS) controls the processor\u2019s power management.

\nIn the Maximum Performance mode, the processor runs at the highest frequency all the time.

  • Performance Per Watt Optimized (DAPC) This mode allows the BIOS to manage the processor power states in order to achieve Performance\/Watt maximized at all utilization levels and workload types while still meeting performance requirements. BIOS also manages system Power Capping in this mode.<\/ul>
    \n
      \n
    • Performance Per Watt Optimized (OS) Under this mode, the CPU Power Management field is set to OS DBPM. This means that the operating system (OS) controls the processor\u2019s power management. The main controls are the processor frequency or performance states ( P-states, P0, P1\u2026Pn), and the processor clock throttling ( T-states, T0, T1\u2026Tn). The OS modifies the power states to achieve the best operating performance, based on the Node Manager inputs and the processor utilization.<\/ul>

        \n
      • Performance Under this mode, the CPU Power Management field is set to Performance and allows the BIOS to program the processor for the maximum performance state.<\/ul>","quoteUsername":"stever3901","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嘿，史蒂夫，
乔恩·科勒（Jon Kohler）在这里，我很乐意与您在Den或Webex上与您同步，并在此处通过Webex和您开放的其他线程，请始终乐于聊天。

我的2美分：亲吻原则，滚动默认值，事情会尖叫。我只想下降“旋钮”，如果您真的想在某物的尾端优化1-2％的1-2％；但是否则，滚动默认值可确保您的环境看起来像每个人的Elses，如果某个地方出现的话，可以更轻松地支撑。
