[Gluster-users] Suggestions for a new glusterfs

[Fedele Stabile]

Hello,
I have two server with a RAID controller and eight disks 4 TB capacity.
I would build a glusterfs. 
 What kind of configuration do you suggest me between these two?
1. Create 2 RAID5 disks on the servers (each RAID is 4 disks, total
12+12 TB) afterthat create on that RAID disks a distributed glusterfs
(one brick each server)
or 
2. Create 8 stand-alone disks (4 each server) and after create on it a
distributed glusterfs (4 bricks each server)
