Chapter 2. Architecture and technical overview 113
IBM AIX Version 7.1
The following minimum level of AIX Version 7.1 supports the Power 770 and Power 780:
AIX Version 7.1 with the 7100-02 Technology Level or later
AIX Version 7.1 with the 7100-01 Technology Level and Service Pack 6 or later
AIX Version 7.1 with the 7100-00 Technology Level and Service Pack 8 or later
A partition using AIX 7.1 can run in POWER6, POWER6+, or POWER7 mode. The best
approach is to run the partition in POWER7 mode to allow exploitation of new hardware
capabilities such as SMT4 and Active Memory Expansion.
2.13.3 IBM i operating system
The IBM i operating system is supported on the Power 770 and Power 780 with the following
minimum required levels:
IBM i 7.1 TR5 or later; Virtual I/O Server requires IBM i 7.1 and VIOS support
IBM i 6.1 with machine code 6.1.1 or later; requires all I/O to be virtual
IBM periodically releases maintenance packages (service packs or technology levels) for the
IBM i operating system. Information about these packages, downloading, and obtaining the
CD-ROM is on the Fix Central website:

Visit the IBM Prerequisite website for compatibility information for hardware features and the
corresponding AIX and IBM i Technology Levels.

2.13.4 Linux operating system
Linux is an open source operating system that runs on numerous platforms from embedded
systems to mainframe computers. It provides an implementation like UNIX across many
computer architectures.
The supported versions of Linux on POWER7+ processor-based servers are as follows:
SUSE Linux Enterprise Server 11 Service Pack 2, or later, with current maintenance
updates available from SUSE to enable all planned functionality
Red Hat Enterprise Linux 5.7 for POWER, or later
Red Hat Enterprise Linux 6.3 for POWER, or later
If you want to configure Linux partitions in virtualized Power Systems, be aware of the
following conditions:
Not all devices and features that are supported by the AIX operating system are supported
in logical partitions running the Linux operating system.
Linux operating system licenses are ordered separately from the hardware. You can
acquire Linux operating system licenses from IBM to be included with the POWER7+
processor-based servers, or from other Linux distributors.
