<div><p>The 6xx, 7xx, Sxx, 8xx, and 890 n-way base servers support logical
|
|
partitions (LPAR).</p>
|

<p>However, the 6xx, 7xx, and Sx0 models do not support the shared processor

|
pool or Linux<sup>®</sup> in

a secondary partition.</p>
|

<p>For upgrade customers, the current physical placement of hardware may restrict

your configuration choices. For server-specific information, consult the Technical

information section on the <a href="http://www.ibm.com/eserver/iseries/lpar" target="_blank">Logical Partition</a> <img src="www.gif" alt="Link outside Information Center" /> web site, and contact your business partner, marketing
|
|
representative, or service specialist.</p>
|
|
<p>Be sure that you have the right hardware and software for your server.
