Hi, I am installing a database (postgresql) server. I am considering two options: - either setup two 6 disks raid10 arrays - or setup three 4 disks raid10 arrays You guessed I have 12 disks :) Raw performance is better on 6 disks arrays, but having 3 arrays allows me to setup 3 tablespaces and maybe to achieve better parallelism. I am under the impression that I will get better results with requests spread over 3 less effective arrays rather than two slightly more effive one. Does it make any sense, or am I totally missing the point ?
