What is the raw performance of your pure storage system?
Next step - run obdfilter-survey on your installation - this will be
your storage performance baseline under lustre.
Next step - run IOR on lustre clients again.
Compare those 3 numbers. You will not achieve more from lustre clients
then from storage performance if lustre servers are fast enough.
