This was one of my biggest issues too. We were expecting to be at 5-10 nodes to start with and then 20-40 nodes in 60-90 days.
But this means we can run all of our database on 1 box :-P … but realistically two. Which means if one box goes offline then I’m at 50% capacity. That and I don’t even have the option for three replicas. I think the ideal would be like a 600-1.2TB drive and something like 32-64GB of RAM and 3x more physical boxes. But they don’t have that config unfortunately. On Thu, Nov 6, 2014 at 12:54 PM, Christopher Brodt <ch...@uberbrodt.net> wrote: > You should get pretty great performance with those FusionIO cards.
