Ok, but in this case instead of a RAID between 2 SSD will be better to use one SSD for journal and one SATA disks for OS. DELL R515 has 12 front disks and 2 internal 2.5'' disks. I'm planning to use these internal disks as journal and OS and the external disks as OSD. > Still, I think that in the distributed nature it shouldn't matter if you > loose a node.
