Wrong focus?
OK, so NVMe (or "envy me" as the marketeers seem to like calling it) gives you a much faster interface than SAS to your SSD. Great! So, if all I want is to attach lots of flash to a server then it looks like a good way to stack lots of JBOF shelves onto a server. Fine, I can rip out all my old SAS JBODs and replace them with NVMeF JBOFs. Problem is I hardly see any SAS JBODs or JBOFs, I mostly see flash in big arrays where the bottleneck is usually the array header, and the value is the centralised consolidation, management, HA, easy presentation and backup offered by the array's software. I suspect the real winners will be the vendors that get the best NVMe features into their arrays, not the JBOF shelf vendors.
