Evaluate the hardware limitations of the iSeries servers

The 6xx, 7xx, Sxx, 8xx, and 890 n-way base servers support logical partitions (LPAR).

However, the 6xx, 7xx, and Sx0 models do not support the shared processor pool or Linux^® in a secondary partition.

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 Logical Partition Link outside Information Center web site, and contact your business partner, marketing representative, or service specialist.

Be sure that you have the right hardware and software for your server. The following table list the LPAR hardware function by model.

Yes

You can create a maximum of one logical partitions for each installed processor using dedicated processors. Or you can use the shared processor pool and specify a partial amount of processors for the partition.
