AIX 5L and logical partitions
AIX 5L V5.3 and V5.2 are supported in logical partitions on the IBM Eserver i5.
AIX 5L V5.3 leverages advanced virtualization technologies. The following table
lists the virtual partition characteristics of AIX 5L V5.2 and V5.3 on the IBM
Eserver i5.
It is recommended that the LPAR Validation Tool (LVT) be used to understand
and plan for deploying AIX partitions on IBM Eserver i5. LVT guides you
through the supported I/O options including which direct I/O adapters are
supported in AIX 5L partitions.
In addition, when planning to run AIX 5L on IBM Eserver i5, it is also important
to obtain licenses for AIX 5L and corresponding Software Maintenance (SWMA).
AIX 5L is licensed by processor and by processor group on the Eserver i5. AIX
5L V5.2 licenses for a pSeries system can be transferred to the Eserver i5. AIX
5L Software Maintenance (SWMA) is required for each AIX 5L license. One year
and three year options are available.
To estimate the amount of server capacity needed to run AIX 5L applications on
logically partitioned Eserver i5 servers, refer to the Sizing IBM eServer i5
Servers for AIX 5L Applications paper at
