all flash
I thought Nimble came out with all flash over a year ago, though looks like that was just an all flash shelf. Their website implies you can pin a workload into all flash if you want, so coming out with an all flash version I don't see as doing much for them other than perhaps to get into gartner's MQ for "all flash" or something. I'd expect the cost for having a few extra nearline drives in the existing solution geared towards all flash is a rounding error.
