<dt><b>Zone Reclaim:</b></dt>
 <dd>
  Zone reclaim allows the reclaiming of pages from a zone if the number of free pages
  falls below a watermark even if other zones still have enough pages available. 
  Reclaiming a page can be more beneficial than taking the performance penalties that 
  are associated with allocating a page on a remote zone, especially for NUMA machines.

<dl>
 <dt>Hardware Prefetch:</dt> 
   <dd>
     <p>This BIOS option allows the enabling/disabling of a processor mechanism 
        to prefetch data into the cache according to a pattern-recognition algorithm
        In some cases, setting this option to Disabled may improve performance. 
        Users should only disable this option after performing application benchmarking 
        to verify improved performance in their environment.
     </p>
   </dd>

 <dt>Adjacent Cache Line Prefetch:</dt> 
   <dd>
     <p>This BIOS option allows the enabling/disabling of a processor mechanism 
        to fetch the adjacent cache line within a 128-byte sector that contains the 
        data needed due to a cache line miss.
        In some cases, setting this option to Disabled may improve performance. 
        Users should only disable this option after performing application benchmarking 
        to verify improved performance in their environment.
     </p>
   </dd>

 <dt>Intel Turbo boost Technology:</dt> 
  <dd>
   <p>Enabling this option allows the processor cores to automatically increase its frequency and increasing 
      performance if it is running below power, temperature.
   </p>
 </dd>       
	 
 <dt>Intel Hyper Threading Technology:</dt> 
  <dd>
   <p>Enabling this option allows to use processor resources more efficiently, enabling multiple threads to run 
      on each core and increases processor throughput, improving overall performance on threaded software.
      In some cases, setting this option to Disabled may improve performance. 
      Users should only disable this option after performing application benchmarking 
      to verify improved performance in their environment.
   </p>
  </dd>
                       
 <dt>Power Technology Mode (Default=Energy Efficient)</dt>
    <dd>
      <p>Values for this BIOS setting can be:
         Energy Efficient: Maximize the power efficiency of the server,Performance:Maximize the performance of the server,
         Custom:Allows the user to customize power and performance related options individually.
      </p>
    </dd>
	 
 <dt>cooling Configuration</dt>
    <dd>
      <p>This feature allows the user to adjust the fan speed manually,If the server is in a stressful environment, 
         the CPU have high temperature, you can adjust the fan speed to 100%.
      </p>
    </dd>
