Hi All,

I have one question about ORION test.

Below is my test data from ORION tool. When the IOPS = 360, the latency time is 11.09 ms. So the current disk system can support 360 IOPS, is it right? If the system have heavier load and IOPS>360, it will cause wait.

        1        2        3        4        5        6        7
8        9        10        11
IOPS        136        230        300        360        407
446        479        505        532        555        570
LAT        7.35        8.67        9.97        11.09
12.28        13.44        14.6        15.83        16.91
18.01        19.28

Thanks
