It's the difference between paying for capacity and paying for consumption. Which is useful, it opens a variety of potential economies and options for both Dell and their customers. Many customers are fine doing their own planning and dislike being billed after the fact. Charging for capacity is what they want. That is the common case now. Many other customers resent bearing the risk of over-provisioning or under-provisioning. Charging for consumption solves that for them. That's what Dell is adding. It's not totally new to them, EMC have done something like this for some time now. Disclosure: I work for Pivotal, which is part of the Dell EMC keiritsu.
