Optimizing AIX 5L performance: Tuning disk performance, Part 1

Learn more about 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(R) disk and I/O subsystem focuses on the challenges ofoptimizingdisk I/O performance. While disk tuning is arguably less exciting than CPU or memory tuning, it is a crucial component inoptimizingserver 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.

 

Optimizing AIX 5L performance: Tuning disk performance, Part 2

Discover how to use appropriate disk placement prior to creating your logical volumes to improve disk performance. Part 2 of this series focuses on monitoring your logical volumes and the commands and utilities (iostat, lvmstat, lslv, lspv, lsvg) used to analyze results.
