We are trying some experiments on our linux raid. We are having
bottleneck in scaling the RAID after ~250K IOPS. Is there a known
issue of s/w max limit or is it simply an issue of configuration?
We have (16 x 64G) SSDs on a RAID0. Our IOPS on this RAID0 stops at
250K (even with lesser or more SSD drives). Whereas we get 540K
IOPS with the same number of SSDs (RAW no RAID). We find a linear
scale-up for each SSD we add to RAID0 until we reach ~250K IOPS
limit. After the RAID0 reaches this limit, its just a straight line
plateau with no increase in performance.
Is there any known issue of the maximum IOPS the s/w can handle?
Cheers,
Arun
