vSphere & esxi 5.5 - changing IOPS limit from default 1000 to 1

I'm reading that you should change IOPS limit from default 1000 to 1. I have an all flash array that my esxihosts use for my WIndows VM's.
I've seen how it's done but I am curious if that also means I need to change Datastore properties in vSphere to use "Round Robin" instead of "Most recently used" to make it work?

Path Selection should be changed to whatever your Storage Vendor recommends, or if they have any additional modules to install.

What all flash array do you have ?

The above require to change that you can send more IOPS from all the Active paths to storage.

you may check the configuration change below below commnad.

esxcli storage nmp device list

Once you change the above to 1 means, the by default 1000  I?O operation per second  send 1000 IOPS down each path before switching.

When you switch that to 1 , it utilizes all the path in optimized way.
