We just bought 2 Linux clusters with (I think) EVA 5000 SANs. 40
total TB of SCSI drives, I think.
Obviously, though, by "we", I don't mean the wife & I. :)

For a given definition of "good enough".
OP is at a Uni, and mentioned using 16-24 drives. Thus I get the

controller won't add that much on top of the cost of the drives,
shelves & power supplies.
