You said Cloud and machines ... then you described something that you
can do on one box with a bunch of drives.

Do you really want a cloud (a bunch of machines with their own drives)
or a large RAID array?

You are getting answers for both now.

If you really do want some kind of cloud storage system and you are
putting the machines in one datacenter ... I would recommend GlusterFS:

GlusterFS has been bought by Red Hat and they offer it in a Storage
solution right now ... And they have CentOS RPMs here for centos5 and
centos6:

If you use the replicated volumes, you can lose bunches of machines and
still have functioning service:
