Iometer: Performance Testing in the Lab

The objective of this DIY Performance Testing Appendix is to give you the tools to improve your foundational understanding of disk drive and storage array performance, as well as to give you the tools that will enable you to affordably benchmark just the important stuff, without great huge hardware labs or great huge investments in learning curve or time to test.

All in the interest of the right tool for the job: Iometer gives useful insights into how and why products perform well with some workloads and poorly with others. These insights help us economically apply the right tools for the job. Really fast (and proportionally expensive) storage hardware should be used for high-transaction storage, ...
