PS has a cycle. It's a low margin business, so every time it starts impacting the bottom line it gets cut. The the business figures out they need PS to close deals. It happens at NetApp, It happens at Microsoft,, heck,,, it happen everywhere.
The problems that NetApp faces are much deeper than a PS haircut can solve. Customers are moving to cloud. On premises sales are dropping. NetApp's competitors have the exact same problem, so it's not NetApp specific. The old channel and partner plays to sell a box just aren't working. NetApp needs to adapt to the new reality to survive, or just roll over and die. Old habits die hard, so I think there is a lot of pain in the future for NetApp until they can figure out how to adapt to the new normal.
Good point from @10nga2nC-8ptk.
