ZFS vs GlusterFS

REF: https://www.jamescoyle.net/how-to/471-zfs-and-glusterfs-network-storage

ZFS offers superb data integrity as well as compression, raid-like redundancy and de-duplication. As a file system it is brilliant, created in the modern era to meet our current demands of huge redundant data volumes.

The problem with ZFS is that it is not distributed. Distributed file systems can span multiple disks and multiple physical servers to produce one (or many) storage volume. This gives your file storage added redundancy and load balancing and is where GlusterFS comes in.
