There are plenty of benchmarking tools available but storage professionals mostly use IOmeter. Unfortunately IOmeter is a little tricky to use. You really need to read the user manual first. I have frequently seen users trying to run IOmeter tests without success.

IOmeter is a collection of tools for running detailed IO benchmarks. It is often used as the tool is able to reproduce the characteristics of current applications and services.
IOmeter consists of a management software that manages and evaluates the particular tests and Dynamo — an executable that run these tests in multiple threads on the local or a remote computer.
Beside Windows, the last version of IOmeter also supports Linux on and bit machines. The graphical management software for controlling the tests is only available on Windows, for Linux systems only the worker engine dynamo can be downloaded. This engine can be downloaded on the project website. For communicating with the management station, Dynamo uses a random high TCP port aus — it is not possible to configure a fixed value. For debugging and testing setups it might be easier to temporarily disable the local firewall of the system you want to benchmark.
It might also be a good idea to also disable SELinux for the test:. Afterwards dynamo can be started on a host mySrv in this example like this to be managed by a Windows PC myDesk in this example :.
The switch -i defines the the name of the Windows machine running IOmeter. It is recommended to start dynamo after IOmeter. The hostname of the system that should be benchmarked is assigned using the switch -m — that value is used by IOmeter on the Windows system. To assign a readable name to the IP inside IOmeter you can specify a string along with the optional switch -n :. Afterwards, dynamo establishes a connection to the management software and starts scanning the host for devices:.
In this example the TCP port is used. Afterwards the system is shown in IOmeter. Now it is possible to configure the particular drives and test scenarios:. Dear Christian, you should need to talk about some workload scenarios and supply some.
I was writing this post back then when I was doing very basic IO analysis during my work on vSphere High Performance essentials.
As you know, IOmeter can be used to benchmark very specific IO application patterns. Message required. Name required. Email required.
