Workload partition functionality, originally introduced in 2007 with the release of IBM AIX Version 6, is a strategic component of the IBM AIX Operating System. With the release of AIX V6.1 TL2 in November 2008, both the core functionality and features related to managing workload partitions have been improved and expanded. This IBM Redbooks publication provides an updated introduction and “how to” guide for system administrators and architects using workload partitions in AIX V6.1 TL2. It builds on the original concepts and practices described in the first Redbooks publication about this topic, Introduction to Workload Partition Management in IBM AIX Version 6.1, SG24-7431 , published in 2007. In AIX 6.2 TL2, significant enhancements to core workload partition functions and new features have been added. Some of the important feature updates provide more flexibility and support for enhanced mobility, improved isolation, and NIM integration. A new and significantly updated version of IBM Workload Partitions Manager for AIX (WPAR Manager), the Web browser-based graphical user interface for managing and monitoring WPARs, is also available. WPAR Manager is a platform management solution that provides a centralized point of control for managing WPARs across a collection of managed systems running AIX.

The most recent maintenance release of IBM AIX 5L Version 5.3 includes a significant set of new features added to the NFSv4 implementation. In 2004, the first IBM Redbooks publication devoted to the topic of NFSv4 implementation in AIX 5L was published: "Securing NFS in AIX: An Introduction to NFS V4 in AIX 5L," SG24-7204. This book provides additional up-to-date information to help IBM clients understand and take advantage of the new NFSv4 functions provided by AIX 5L Version 5.3 with the 5300-03 Recommended Maintenance Package. The NFSv4 implementation in AIX 5L has now expanded to provide core features that make it capable of providing a much broader range of distributed file system services than any prior version of NFS. The scope of this book includes methods for implementing NFSv4 in the enterprise and extensive coverage of methods for how it can potentially be used as a migration target for existing AFS-based and DCE/DFS-based enterprise file systems.
