Three suggestions in descending order of preference:

1) Use distribute/replicate in Gluster to provide a RAID-like setup.  IMHO using
Gluster doesn't make a lot of sense unless you have 2+ servers and if you do you
can use distribute/replicate to create volumes that act like mirrored (via
replicate) and striped (via distribute).  This will maximize the available disk
space because you aren't losing drives to parity and any drive failures are
fixed by replacing the drive and use Gluster's heal.

2) Use mdadm to create RAID out of JBOD, then use that to create your brick.

3) Purchase a hardware RAID controller (3Ware/LSI).  This the highest performing
solution, but also the most expensive.
