Re: Call them what you want
Although I understand the sentiment and do believe Gartner are skewing the market (at least on paper), the reality is that a customer buying 3PAR will be provided choices e.g 7450 AFA or 7440 hybrid.
Both are effectively the same price and performance with identical flash configurations, the decision of whether to commit to all flash is ultimately the customer's not HP's.
Whilst selling the 7440 does harm HP's overall AFA numbers vs AFA only suppliers it provides customers with an insurance policy and that's really why the 7440 exists.
Whether Customers want to take that route is a decision only they can make.
