Typically one starts looking at hardware solutions after identifying the
needs of the target application/workload.
Is the proposed storage cluster system simply a proof of concept
testbed, or will it actually be tasked with real work? If the latter
I'd rethink your iSCSI export to NFS server idea. You mentioned only 8
disks. Just drop them directly into the NFS host and avoid many
potential headaches down the road.
