In this document on the earlier Smart Array HP Controllers it is stated that "With a 70/30 read/write workload using 8 KiB requests, the SSD's range from ~8K-12K IOPS per drive and ~6 drives exhaust the ~50K IOPS limit of the Smart Array. More drives can be added for capacity requirements but performance will not scale well after 6 SSD's".

 

What is the approximate IOPS limit of the P420i Smart Array Controller ?

Use IOMeter with 512byte/block and with 24 IO queue per targer, you must get at leas 150.000+ IOPs.

 

HP said the controller B320i can reach 316.000 IOPs:

According to HP Smart Array Controllers and basic RAID performance factors, the IOPS limitation of the P420i controller chipset is 200,000 random 4K IOPS. The previous generation P410 controllers is 50,000 random 4K IOPS.
