your server.</p>

<div class="section"><p>The information in this topic describes the required hardware
|
||
|
|
needed on your server to successfully create a logical partition.</p>
|
||
|
|
<p>The
|
||
|
|
ability to dynamically move resources between partitions is available on both AS/400<sup>®</sup> and iSeries™ models
|
||
|
|
that support logical partitions. Uni-processor partitioning capability and
|
||
|
|
shared processor pool capability is available on V5R1 and V5R2 partitions
|
||
|
|
running on iSeries models
|
||
|
|
800, 810, 820, 825, 830, 840, 870, and some 270s. Other hardware for the logical
|
||
|
|
partition is either optional, or you can switch it between two or more logical
|
||
|
|
partitions. </p>
|
||
|
|
<p>You can read Plan for logical partitions to help you decide
|
||
|
|
what hardware you need. To learn more about the hardware you can use with
|
||
|
|
logical partitions, click the piece of hardware you want to learn more about
|
||
|
|
in the following picture:</p>

A bus is a conductor that is used for transmitting signals or power.</li>

|
|
<li class="ulchildlink"><strong><a href="rzaitdynamic.htm">Dynamically switching IOPs between partitions</a></strong><br />
|

A powerful advantage of logical partitions is ability to dynamically switch an IOP from one partition to another.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzaitiodevice.htm">Logical partition concept: IOP</a></strong><br />
|
||
|
|
The IOP attaches to the system I/O bus and one or more input/output adapters (IOAs). The IOP processes instructions from the server and works with the IOAs to control the I/O devices.</li>

<li class="ulchildlink"><strong><a href="rzaitspdpci.htm">Logical partition concept: SPD and PCI</a></strong><br />
