2.12.4 Virtual I/O Server

The minimum required level of Virtual I/O Server for both the Power 720 and Power 740 is
VIOS 2.2.2.2.
Statement of Direction (SoD): IBM intends to provide to those clients with VIOS 2.2.1 the
ability to run that environment on the Power 720 and Power 740.
IBM regularly updates the Virtual I/O Server code. To find information about the latest
updates, visit the Fix Central website:

2.12.5 Java versions that are supported

There are unique considerations when running Java 1.4.2 on POWER7 or POWER7+
servers. For best use of the performance capabilities and most recent improvements of
POWER7 technology, upgrade Java-based applications to Java 7, Java 6, or Java 5 when
possible. For more information, visit the following location:

2.12.6 Boosting performance and productivity with IBM compilers

IBM XL C, XL C/C++, and XL Fortran compilers for AIX and for Linux use the latest
POWER7+ processor architecture. Release after release, these compilers continue to help
improve application performance and capability, exploiting architectural enhancements that
are made available through the advancement of the POWER technology.
IBM compilers are designed to optimize and tune your applications for execution on IBM
POWER platforms, to help you unleash the full power of your IT investment, to create and
maintain critical business and scientific applications, to maximize application performance,
and to improve developer productivity.
The performance gain from years of compiler optimization experience is seen in the
continuous release-to-release compiler improvements that support the POWER4 processors,
through to POWER4+, POWER5, POWER5+, POWER6, and POWER7 processors, and now
including the POWER7+ processors. With the support of the latest POWER7+ processor
chip, IBM advances a more than a 20-year investment in the XL compilers for POWER series
and IBM PowerPC® series architectures.
