tripleX :
When aming this statement, did you take Littles Law into consideration:
Every single one-second average falls between 28,500 and 38,000 IOPS (0.84 and 1.12 ms)
No, we didn't, but can you be a little more clear with your question? I am not an expert in the area, but the law, as it applies to performance testing, is valid if the number of jobs in the system is equal to those being completed. Meaning that no new jobs are created in the system and no jobs are lost forever. So, if jobs were being lost, you might see consistent performance centered around the bottleneck, which is not the device under test. Since the system is artificially creating and tracking IOs, I don't believe any are being lost or accidentally created. Also, with our Enterprise Video testing, which I wrote to test a specific use-case, the data is generated and validated as it is written, so there is no chance of data loss. If that doesn't answer your question, please let me know, I am always interested in new subjects....
