I'm still reading about ZFS but doesn't it involve a form of software RAID
integrated with the rest of the storage system?
As I understand it, it allows a given filesystem to exist across multiple
devices, and for the filesystems you have to more freely use the available
space.
I don't think it provides redundancy, at least not on a full-system level
like RAID does. Simple google searches find plenty of people putting ZFS
on top of a RAID.
I think it does help in a lot of the same scenarios where LVM helps: freely
using JBOD.
