xSeries Overview
Porting
Porting to xSeries servers with either the Windows or Linux operating systems is
similar to porting to other Intel-based platforms. Although all IA-32 operating
systems share many similarities, there are differences between each type of operating
system which may require specific changes. Some applications may operate across
several versions of Linux, for example, but generally some porting effort is
required.
xSeries servers have for some time supported the Linux
operating system native on all servers. For those applications currently
running Linux on other platforms (such as iSeries or pSeries servers), it is
possible to run your application without modification on either Red Hat Linux
or SuSE Linux on xSeries. Porting may be required for
porting from other versions of Linux.
The goal of this Web site is to aid you in your xSeries porting
effort. This includes information on porting from other UNIX platforms such as
HP-UX, AIX, or Sun Solaris to the Linux operating system, as well as Windows.
We also include reference materials such as white papers and books that provide
in-depth information on topics relevant to the porting process.

Infrastructure
Porting the application code itself to the xSeries
platform is one part of a successful solution on the xSeries solution. It is
also necessary to perform QA and benchmarking, as well as long-term support of
the xSeries server. Integration of the xSeries ported code into the regular
build process for the current release of the application as well as future
releases should also be determined. You should consider this as an investment
in the infrastructure
-- in the systems and skills necessary to effectively test, deploy and
support the xSeries platform.

Tailoring
After you have completed not only the port of your application (porting), but
also the QA and build integration (infrastructure), you will still want to consider
the following which we call tailoring. Customers usually like to have a
familiar look and feel. This may mean having the same application
interfaces across all of the platforms that it runs on, or it can mean
tailoring part of the look and feel to make it similar to other applications on
xSeries. This is also where aspects of systems managements and availability
come into play. This is what we call tailoring
to xSeries.
It is likely that you will only tailor a
few of the topics. Still, you
should consider all the topics to see if your application could benefit.
A high level description of each of these topics can be found on the
tailoring to xSeries
page.
