LSI MegaRAID SAS/SATA 9265-8i – IOMeter Cont’d and PassMark Initial Tests

In an all out effort to push maximum IOPS we loaded a 512b random workload 3 workers @ QD 128. The system spiked above 420,000 IOPS a few times but it was very difficult to capture a screenshot.  This was a result of the limitation of our hardware under this extreme loading of my processor which was causing severe “choppiness”. I can confirm that it was a limitation of the hardware in use as server environments in enterprise applications use dual CPU systems. I am very curious as to how this would handle with a 6-core processor as a 990X would surely be able to get us up to the 460K IOPS. My highly overclocked 920 @ 4.65 was really struggling with this load!

512B random read, 128QD,  3 workers.

PASSMARK

I am using this benchmark to highlight server usage loads and the performance of this card. It is pretty amazing that, in a few of these tests, it outstrips the Areca 1880 by a large margin even though that controller was running entirely in cache!   The brute force of the 9265-8i is simply amazing.

These types of mixed read /write file tests are very demanding on the storage subsystem.

If you want more detailed information on the testing, parameters and configurations used in testing, feel free to hit the forums! I will be happy to answer any questions, and as long as I have the hardware, if there is anything I have missed, I would be happy to run some tests for you and there will also be some more detailed presentations on 4k scaling for you enthusiasts out there 🙂 ~ Paul
