Maximum IOPS

Hello! 

Sorry if this a little confusing, I am still fairly new to the storage array system! I am curious as to if there is a way to see the maximum IOPS allowed on my array. 
Context: We routinely perform updates to databases on multiple servers across the array and due to our previous SAN's limitations we are currently limiting the number of databases we update simultaneously. Looking at the dashboard I can see that there doesn't seem to be any large spikes in the IOPS while performing said updates, but was curious if there was an easy way for me to compare the numbers I'm seeing to the maximum allowed to try and get a metric of how good/bad the performance is. Thanks in advance!
