Get to know the IBM AIX operating system! The topics covered include: - Basics of the AIX operating system; - Virtualization, PowerVM, Virtual I/O Server; - Installation and maintenance of the AIX operating system; - Management of users, disks, and the file system; - Backup and system diagnostics; - Performance tips; - Security features. Operating systems from the UNIX family are known for their high reliability and performance. This is why many companies use such systems to manage key application servers. One of the systems that belongs to this family is AIX, which has gained popularity in recent years due to its significant potential for virtualization as well as the fact that its security configuration meets the strictest security requirements.

The aim of this IBM Redbooks publication is to provide a technical reference for IT system administrators in organizations that are considering a migration from Sun Solaris to IBM AIX 5L-based systems. This book presents a system administrator view of the technical differences that exist and the methods that are necessary to complete a successful migration to AIX 5L-based systems. This book is designed primarily as a reference for experienced Sun Solaris 8 or 9 system administrators who will be working with AIX 5L. This book is not an AIX 5L administration how-to book for system administrators who are beginners, but rather a guide for experienced administrators who have to translate a given Solaris system administration task to AIX 5L.

NFS Version 4 (NFS V4) is the latest defined client-to-server protocol for NFS. A significant upgrade from NFS V3, it was defined under the IETF framework by many contributors. NFS V4 introduces major changes to the way NFS has been implemented and used before now, including stronger security, wide area network sharing, and broader platform adaptability. This IBM Redbooks publication is intended to provide a broad understanding of NFS V4 and specific AIX NFS V4 implementation details. It discusses considerations for deployment of NFS V4, with a focus on exploiting the stronger security features of the new protocol. In the initial implementation of NFS V4 in AIX 5.3, the most important functional differences are related to security. Chapter 3 and parts of the planning and implementation chapters in Part 2 cover this topic in detail.
