2. © 2011 IBM Corporation IBM Power Systems 2 Summary IBM significantly enhanced the AIX ® Release and Service Delivery strategy in February 2011 for AIX 6 and AIX 7 The principal changes* are: Three years of support for each Technology Level (TL)** A single Technology Level per AIX version, per year Service Packs will be released approximately 4 times per year per Technology Level * All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only. ** Due to variations in the release dates of Technology Levels from year to year, some Technology Levels will be supported for slightly more than three years and some will be supported for slightly less than three years. A three year service life for each Technology Level is an objective, not an absolute limit. The service life of Technology Levels will also be limited by the end of service life for the underlying AIX release

10. © 2011 IBM Corporation IBM Power Systems 10 Benefits of the new AIX Release Strategy*  Longer support for Technology Levels –More closely matches client deployment requirements  Single Technology Level per year, per version, and about one Service Pack per quarter –Fewer updates reduce administrative workload  New hardware is supported on prior Technology Levels –Easier integration of new hardware into existing environments *All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only.

13. © 2011 IBM Corporation IBM Power Systems 13 Question & Answer Q: Why did you make these changes? A: The historical purpose for multiple Technology Levels per year was to support the introduction of new hardware. The support for new hardware on prior TLs (implemented in 2007) and exploited with the introduction of POWER7 allowed us to do away with the “Spring” TL. Q: Will I always have to move up to the latest Service Pack in order to get an Interim Fix? A: Interim Fixes are intended to provide an immediate, short term solution to a specific problem. The intent is to provide Interim Fixes without requiring clients to apply the latest service pack, but there are cases where there might be a dependency on a Service Pack that would require applying a Service Pack before an Interim Fix, but that is intended to be an exception. Q: Why are you including Hardware in Service Packs – aren’t you introducing additional risk by including new hardware support in the fix stream? A: No. When we analyzed historical problems in AIX, we found that new hardware support was not a big contributor to problems within AIX. Most new hardware only requires a minor change to configuration tables within AIX or, in some cases, a new fileset for new hardware, neither of which would typically be a problem for existing clients. *All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only.

14. © 2011 IBM Corporation IBM Power Systems 14 Question & Answer Q: Why is the a delay in shipping the Service Packs on the old Technology Levels to support new hardware? A: It takes time to verify (test) the new service packs on the new hardware. Because we are supporting up to six Technology Levels/Service Pack combinations for every new piece of hardware, we cannot test all levels simultaneously. We focus on testing the new Technology Level (which may include new software features) and then verify the hardware on the older Technology Levels. Q: How will I get a fixes – right now, if security APAR comes out, it is only released for the latest current level. A: There will be APARs released for each Technology Level. These APARs will be cross referenced to each other. Q: Why doesn’t the new strategy include AIX V5.3? A: AIX V5.3 is nearing end of life with the End of Marketing for AIX V5.3 set for April 2011. Q: I am currently running AIX 6 TL5. Can I stay on this release for three years? A: No. The new release strategy becomes effective with AIX 6 Technology Level 6 (TL6). Q: How will I get bootable media for new hardware on previous Technology Levels? A: A PRPQ will be available to allow clients to order bootable media to support new installation of AIX on new hardware for previous Technology Levels. *All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only.

15. © 2011 IBM Corporation IBM Power Systems 15 Interim Fix Guidelines/Policies for Maintenance*:  If a client is at the latest level and find a problem – they can get an Interim Fix  If a client finds a problem that is already in a SP - they need to install the latest SP (or, at a minimum, an SP that includes their fix)  If it is a critical problem and/or the client can't install a SP - an interim fix can be offered and support will recommend they move to the latest SP during their next maintenance window  If a client finds a new, unique problem at any supported level (within the 3 year support window for a TL) - they can get an Interim Fix on their current level (if it's possible)  If a client finds a new unique problem on a prior SP, has multiple Interim Fixes installed, which are included in later SP - they must move to the latest SP before getting another Interim Fix  If a client has multiple Interim Fixes and only some of them are in a later SP - they must move to the latest SP and another Interim Fix will be bundled with their prior Interim Fixes on the current level *All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only.
