No tiering in XIV
No tiering in XIV is actually a benefit, given how complex storage tiering is (according to the description in this article).
The bottom line is: what is the performance the storage array if providing your applications and how much time & effort does the storage administrator invest (waste?) on performance management.
For performance - check out the recent SPC-2 results for XIV Gen3 (and soon, SPC-1 too). For performance management with XIV - well, there isn't any.
