<h1 class="topictitle1">Logical partition concept: dedicated processor</h1>
|
|
<div><p>Dedicated processors are whole processors that are used exclusively
|
|
by the partition to which they are assigned. The dedicated processor handles
|
|
the processing for a specific logical partition.</p>
|
|
<p>If you choose to assign dedicated processors to a logical partition, you
|
|
must assign at least one processor to that partition. Likewise, if you choose
|
|
to remove processor resources from a dedicated partition, you must remove
|
|
at least one processor from the partition.</p>
|
|
<p>To adjust to changing workloads, you can move dedicated processors within
|
|
the minimum/maximum values you establish without needing to restart the partition.
|
|
These values enable you to establish a range within which you can dynamically
|
|
move the resource without needing to restart the logical partition. When you
|
|
change the minimum/maximum values, it requires you to restart the partition.
|
|
Minimum values dictate what is required to restart the partition. If the minimum
|
|
value is not met for all logical partitions, only the primary will restart.</p>
|
|
<p><br /><img src="rzait517.gif" alt="Picture showing a partitioned iSeries using dedicated processors." /><br /> </p>
|
|
<p>For example, a server with 4 physical processors can have 3 logical partitions
|
|
with two partitions having 1 dedicated processor and one partition having
|
|
2 dedicated processors.</p>
