Does any open source I/O benchmarking tool support ramping up IOPS?
I know that I can use fio to benchmark my disks with any given static workload. However, does any open source high quality benchmarking tool support doing a test where I select following parameters as constants:
- Test file size (e.g. 500 MB)
- Static QD (settable at least to 1, 2, 4 and 8)
- Workload (e.g. random 4k read over whole file span)
- Direct I/O access (similar to
libaiooffio) - Define max latency in µs
And the benchmark should slowly increase IOPS until latency goes over set limit after which the benchmark is done. The test result would be latency for each IOPS value, or better yet, minimum+average+max latency for each IOPS value.
Basically I'm asking a tool that can do similar benchmarking required for this storagereview.com graph:
I know that I can repeatedly run fio with different settings to generate the required data but I'm wondering if there's some premade tool for this purpose. Does such a benchmark tool exists?

fio has an option that discovers the highest IOPS that can be done under a certain latency... From the "I/O latency" section of the fio documentation:
latency_target=time
If set,
fiowill attempt to find the max performance point that the given workload will run at while maintaining a latency below this target. When the unit is omitted, the value is interpreted in microseconds. Seelatency_windowandlatency_percentile.
Please see the whole I/O latency section of the fio help as there are a bunch of operations that interact together. You may also find fio's Steady State mode and the separate tool Diskplorer (which itself drives fio) useful. However, I note you've clarified your question and the aforementioned options/tools don't generate latency numbers at a set number of different "max IOPS" points (however Diskplorer does generate latency / IOPS against I/O depth numbers).
Away from fio, you could also look at using the vdbench tool that StorageReview themselves actually seem to be using in that review (despite their page claiming that they use fio) but you'll have to wave goodbye to a libaio like submission - I'm fairly sure vdbench doesn't do platform specific AIO because it is trying to be platform agnostic (so it can only use multiple threads/processes to up the depth).

If I've understood correctly, thelatency_targetallows me to figure one IOPS number for one pre-decided max latency. That does not give me performance numbers for lower IOPS (see the example graph in the question). I can runfiorepeatedly with different IOPS numbers and graph the latency but I'm wondering if there exists a better tool for the job.

I'd say Diskplorer is as close as I've seen in terms of a premade tool that usesfio(and perhaps wouldn't be too much work to change the code do what you wanted). Did you also see my mention of thevdbenchtool (which is what Storage Review appear to be using)?
