Having persistent data on local storage will make your life very hard
when the time comes around to secure and back up that important data.
I think you can enjoy both worlds by using temporary local storage for
I/O-intensive calculation, and then store the important final results
to a central storage you can easily secure and back up.
If what you want to do is pool together your local storage to get
something that looks like a cheap central storage, then you are in the
realm of ceph/gluster/hyper-converge. There is a performance and
complexity overhead to using those technologies. (And not everything
is supported by oVirt yet)
