IOPS calculating tool

[Samandar]

Hi,

Can anyone tell me please, if there is a tool where I can calculate IOPS of HPE Storage ?

I have an oca configuration, and the customer wants to know about IOPS of the storage. How and where can I calculate IOPS ?

For example if I have configuration of Primera storage

You ask that like there should be some magic number. There isn't. 

IOPS depend on the read/write ratio and the block size from the hosts. A host mostly reading 4KB blocks will have a much higher IOPS rate than a host mostly writing 64KB blocks. Inversely, 4KB blocks tend to a much lower throughput than 64KB blocks.

You can't compare apples with oranges. If you are looking for a comparison number, you have to know what the other system(s) is(are) using for write percent and block size.

It's best to capture performance data from the hosts and use that as the IO characteristics to then feed to something like NinjaStars.
