Lustre 1.6 Operations Manual

CHAPTER 17
Benchmarking
The benchmarking process involves identifying the highest standard of excellence
and performance, learning and understanding these standards, and finally adapting
and applying them to improve the performance. Benchmarks are most often used to
provide an idea of how fast any software or hardware runs.
Complex interactions between I/O devices, caches, kernel daemons, and other OS
components result in behavior that is difficult to analyze. Moreover, systems have
different features and optimizations, so no single benchmark is always suitable. The
variety of workloads that these systems experience also adds in to this difficulty.
One of the most widely researched areas in storage subsystem is filesystem design,
implementation, and performance.
This chapter describes benchmark suites to test Lustre and includes the following
sections:
■ Bonnie++ Benchmark
■ IOR Benchmark
■ IOzone Benchmark
