Hi. There's also another option. You may also want to look into GlusterFS. Each option has its own features and drawbacks. As far as I know Ceph requires at least 3 identical storage nodes which may be somehow more expensive than other options. Choosing a clustered filesystem depends on several factors suchas whether you need replication or not and what level of HA do you want. I myself am curious about which option do most experts here choose.
