I’m looking at purchasing a server to run some SciDB testing on, and, since the user guide says to consult the forum for advice, ended up here. I was looking specifically at Dell r720s - dual socket Xeon E5 boxes that can hold either 8 or 12 3.5" disks. Is that a reasonable server for SciDB purposes, or should I be looking at configurations with more or less disks per core? Roughly how much memory should be available per core? Finally, how important is HW RAID - would a typical deployment on a node like the above use JBOD + an instance per disk, or a smaller number of instances (perhaps just one) per node?
Thanks for any recommendations,
