AIX 5L is an open, standards-based OS that conforms to The Open Group’s Single UNIX Specification Version 3. It provides fully integrated support for 32- and 64-bit applications. AIX 5L supports the IBM System p5™, IBM eServer™ p5, IBM eServer pSeries®, IBM eServer i5 and IBM RS/6000® server product lines, as well as IBM BladeCenter® JS2x blades and IntelliStation® POWER and RS/6000 workstations. In addition to compliance with UNIX standards, AIX 5L includes commands and application programming interfaces to ease the porting of applications from Linux to AIX 5L.

AIX 5L Version 5.3 offers new levels of innovative self-management technologies. It continues to exploit current 64-bit system and software architecture to support advanced virtualization options, as well as IBM POWER5 and POWER5+™ processors with simultaneous multithreading capability for improved performance and system utilization. AIX 5L V5.3 is enhanced to support the IBM Virtualization Engine systems technology innovations available on POWER5 and POWER5+ systems, including Micro-Partitioning™ and Virtual I/O Server support.
