SSD Journal

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
