Re: Tegile and Nimble aren't "really" AFAs: they were hybrids like Infinidat until recently
That's because you are vastly under-estimating the patented innovations the system leverages with regard to data placement and accessibility. Think "machine learning" algorithms rather than "pre-fetch". Those are absolutely critical in order to hit the >AFA performance numbers we're talking about here, or else, as you say, we would have reads coming off NL-SAS. That's what hybrids do - not us, we are a Cache Array. We use cache for host I/O's and NL-SAS for persistent storage. It is a modern, innovative design, and frankly one of a kind. Hope this helps.
