Dear Power Systems clients:
We are very pleased with the response to the recent announcements on AIX® 7 and POWER7® products. The new POWER7 servers — including the ones available for IBM PureSystems, our new family of expert integrated systems — run AIX 7, AIX 6 and AIX V5.3 — all with binary compatibility for applications currently running on AIX 6 and AIX 5L — and AIX 7 will even run on older servers based on POWER5™ and POWER4™ processors. This broad support for multiple levels of the AIX operating system on multiple generations of POWER systems is the strongest ever.
Some of you would like to hear our commitment to binary compatibility directly from me. So here it is: We are offering a guarantee1 that your applications, whether written in house or supplied by an application provider, will run on AIX 7 if they currently run on AIX 6 or AIX 5L – without recompilations or modification. Even well-behaved 32-bit applications from AIX V4.1, V4.2, and V4.3 will run without recompilation.
I encourage you to find out for yourselves. We assume (and require) that these applications comply with reasonable programming standards, but if they do and the applications will not run on AIX 7, contact us. We will investigate and assign our developers to work on any binary compatibility issues. That’s how confident I am that we have done things right in AIX 7.
The unique qualities of AIX — virtualization, security, performance and quality — have won many new clients to AIX. AIX 7 will be the next step forward in the evolution of UNIX, while allowing existing AIX 6 and AIX 5L applications to continue to run. AIX is and will remain the strategic UNIX operating system for IBM.
Thank you for your continued confidence in IBM Power Systems servers and in AIX. Keeping your applications up and running is one of our primary goals. I want you to know that we have taken great care to insure that when you upgrade to AIX 7, your AIX 6 and AIX 5L applications will not only run unmodified, but you will also be able to take advantage of the new innovations in AIX 7.
