Simon covers the details here:
Now if you used any of the old versions of PSO you know it can smart provision across Pure Storage arrays with a single storageClass for block and one for file. Today I am proud to share the mysterious and sometimes confusing third storageClass
pure is no longer installed with PSO 6. The long story is that storage class was to support legacy systems that use the 1.0 version of our driver. There has been 2.5 years to get used to
pure-block. So now with the upgrade you can make the right choice.

Now you have only two obvious choices.
