Gluster users - Sep 2017 - First Gluster Volume deploy: recommended configuration and suggestions?

Dear users,

I just started my first Gluster test volume using 3 servers (each server
contains 12 hdd).
I would like to create a "distributed disperse volume? but I?m a little bit
confused about the right configuration schema that I should use.
Should I use JBOD disks? How many bricks to be defined? Ideal redundancy value?
Ideal disperse-data count value? 6x(4+2) or 3x(8+4) volume configuration? Which
one is the best one and why?
I?m trying to refer to the admin guides that I have found on internet but, in my
case, it?s very difficult understand details because of some missing
information.

Do you have some useful suggestions about the right configuration to be selected
in order to reach an optimal fault tolerance and performance level?
This is my first test configuration (see the gluster volume info command output
below), what do you think about it?
I created it using gdeploy and I used all the bricks, is it ok? Or should I use
only part of them and in a specific order?
