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. Being human, most of us hate to read the manual and with IOmeter this can lead to problems. I hope this short post will help you to get the wanted results. First off, you need to know that IOmeter recognizes 2 different volume types:.
With un-partitioned disks you can start the test at once, but to run with formatted iomter you need a test file. The test file must be placed in the root directory and named: By default IOmeter will create the test file if not found. The problem is that nowadays volumes are very big, and IOmeter runs very slowly. Please run it in order ioeter create iobw. To find out your storage performance there are a few typical test configurations you may want to run.
In our case the sequential read shows the best result: Please make your settings very carefully and make sure all workers use the same test configuration! IOmeter is such a great tool for understanding storage performance. Dynamo is the server component of IOMeter for Linux.
A Few practical tips about IOmeter | Open-E Blog
You can integrate it and add some basic controls in the UI so that someone from a Windows system can connect to Dynamo remotely and run tests. This gives the most accurate picture of storage performance. Many people make the mistake of trying to test performance on the initiator side without truly understanding what manyal underlying storage is capable of delivering.
We have a small update that can provide some performance on Reads and Writes for Units that have not been formatted — email me at pre-sales open-com and I will provide this for you also for the NICs as well you will need another DSS V6 to perform this. The problem with Iometer is the results output depend on the size of the iobw. If you create a small file you get very good results because you are running in cache. If you create a large.
Use with care and use consistently. Unfortunately people are using manusl all over the internet without clarifying how they have setup the tests. Is there any CLI command to stop the running IOmeter execution without manuual user interface stop button. The IOmeter tool is a separate software and there is no option to use the CLI command, since it is iojeter included in our product.
You can find more information about the IOmeter here: Anybody has seen this issue on their end? An explanation of manuwl to do this is available in our knowledgebase: Can any one tell me how to configure? Unfortunately we are not able to help you by answering your comment. Please create a ticket with our Technical Support team. They will send you a personalized IO meter profile.

For example, on a fast Intel SSD 1. In Open-E JovianDSS in turn, the read results may take a while, even up to a few hours in some cases, before read cache learns the data. This would return a large number that might not necessarily represent real world more random type mannual.
