But that's a lot of extra overhead too. You need monitors, OSDs, metadata servers, etc... If you're comfortable with the node being a single point of failure, you can do a lot with a single storage node connected to a JBOD and serving data over NFS. And even if the node is the unit of failure, you can attach a SAS JBOD to multiple servers if you'd like. In my position, in addition to the added cost, I just don't have the physical rack space for the extra servers required for ceph.

> don't have the physical rack space for the extra servers required for ceph Sure, it depends but the 140 drives (mentioned by secabeen) alone will take up a huge amount of space. Maybe I just wanted to point out that there might be a point when you have maxed out the storage capability of a single node and might want to consider a distributed storage setup.

  They take about 14U total. (3x4U 60-drive JBOds, and a 2U server.) Big, but not huge.
