You don't have to leave all your redundancy to Gluster. You can put Gluster on two (or more) systems which are each running RAID5, for instance. Then it would take a minimum of 4 drives failing (2 on each array) before Gluster should lose any data. Each system would require N+1 drives, so double your drives plus two. (There are reasons to consider RAID other than 5, but I'll leave that discussion out for now.)
That's great with a few nodes, but the problem is with Gluster and many notes. We run all our notes with RAID6, but the more nodes you have the more likely you will have a node failure. This is what I think Jeff was worried about.
