I’ve just been updating a series of articles on AIX 7 and the new functionality.The first three cover the basics performance details.For Part 1:

Learn more about configuring and monitoring AIX 7 based on the investigations of AIX 7 beta compared to the original articles based on AIX 5L. The article covers the support for direct I/O, concurrent I/O, asynchronous I/O, and best practices for each method of I/O implementation. This three-part series on the AIX® disk and I/O subsystem focuses on the challenges of optimizing disk I/O performance. While disk tuning is arguably less exciting than CPU or memory tuning, it is a crucial component in optimizing server performance. In fact, partly because disk I/O is your weakest subsystem link, you can do more to improve disk I/O performance than on any other subsystem.

Discover how to use appropriate disk placement prior to creating your logical volumes to improve disk performance. These investigations are based on AIX 7 beta and updating information from the original AIX 5L version of this article. Part 2 of this series focuses on monitoring your logical volumes and the commands and utilities (iostat, lvmstat, lslv, lspv, and lsvg) used to analyze results.

Part 3 of the AIX 7 performance series covers how to improve overall file system performance, how to tune your systems with the ioo command, and how to use the filemon and fileplace utilities. You will also learn about JFS and JFS2 that is available in AIX7.
