Re: Tegile and Nimble aren't "really" AFAs: they were hybrids like Infinidat until recently
It is interesting that the 3 companies you mentioned pivoted to all-flash. To answer your question whether they should have stuck to hybrid rather than moving to all-flash - I guess it depends. At the end of the day, it's the job of the storage companies to deliver what customers want. Every customer wants reliability, performance, scale/density, simplicity/ease of use and lowest cost/TCO. That's what matters. It's on the storage companies to design architectures that deliver those 5 things to the enterprise. Some architectures require all-flash to deliver on those customer requirements because they can't get performance or simplicity without it....INFINIDAT is a software centric design and delivers across all of those requirements to the highest standard and because it's able to leverage whatever is the lowest cost media for the persistent storage layer (today and for the foreseeable future that's NL-SAS) without compromising performance, reliability, simplicity or density it's going to deliver a TCO that the all-flash array architecture can't touch.
