Hello,

Looking at final stages of planning / setup for a CEPH Cluster.

Per a Storage node looking @

2 x SSD OS / Journal
10 x SATA Disk

Will have a small Raid 1 Partition for the OS, however not sure if best to do:

5 x Journal Per a SSD
10 x Journal on Raid 1 of two SSD's

Is the "Performance" increase from splitting 5 Journal's on each SSD worth the 
"issue" caused when one SSD goes down?

Thanks,
Ashley
