|

|
|
<div><p>Partitions can use one of two modes of processors on the iSeries™ server.
|
||
|
|
The results of your capacity planning and system hardware configuration will
|
||
|
|
help you make a decision about utilizing dedicated processors or the shared
|
||
|
|
processor pool for each partition. </p>
|
||
|
|
<p>Depending on workload demands for each partition, one partition can use
|
||
|
|
dedicated processors and another partition can use the shared processor pool.</p>
|
||
|
|
<p>Dedicated processors allows you to assign a whole processor to a partition.
|
||
|
|
You can assign dedicated processors to a partition as long as processors are
|
||
|
|
available or unassigned.</p>
|
||
|
|
<p>The shared processor pool allows you to assign partial processors to a
|
||
|
|
partition. The processors are held in the shared processing pool and are shared
|
||
|
|
among the logical partitions. A minimum of 0.10 processing units per virtual
|
||
|
|
processor can be configured for any partition using shared processors. The
|
||
|
|
primary partition may require more than 0.10 processing units when starting
|
||
|
|
secondary partitions, otherwise timeout conditions may occur with resources
|
||
|
|
communicating directly with the primary partition. Each system processing
|
||
|
|
capacity and partition configuration needs to be evaluated to determine reasonable
|
||
|
|
processor units for primary and secondary partitions.</p>
|
||
|
|
<p>To adjust to workload demands, you can move shared processing resources
|
||
|
|
without needing to restart the partition. Use of the shared processor pool
|
||
|
|
is preferred for small (less than one processor) partitions or where the use
|
||
|
|
of a whole processor increments are too great for the partition.</p>
