I have done this with 4 IET target server's in a RAID10. And it is very
fast. Make sure to use mdadm for software raiding. I did have a mounting
issue on boot up. I had to setup a small delay and a separate mount from
the fstab. Maybe someone else has a fix for this. I also ran RedHat GFS
over it so I could share the storage between the 4 servers. So I made
myself a mini cluster. Was pretty fast. So the target's were also
client's mounting all the other target's and itself then creating the
raid and sharing it with GFS.
