It's not exactly a single system SSG-F618H-OSD288P* 4U-FatTwin, 4x 1U 72TB per node, Ceph-OSD-Storage Node This could actually be pretty good, it even has decent CPU power. I'm not a big fan of blades and blade-like systems - sooner or later a backplane will die and you'll need to power off everything, which is a huge PITA. But assuming you get 3 of these it could be pretty cool! It would be interesting to have a price comparison to a SC216 chassis or similiar, I'm afraid it won't be much cheaper.
