Hi all, I'm planning on deploying an ES cluster soon; machines will be equipped with 4 x 240GB SSD drives, and I wonder what's the pros and cons of having multiple data dirs vs having a setup with the 4 drives in RAID0 ? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Multiple data dirs seems pointless, what were you hoping to achieve with that? I'd go RAID0, let ES handle the redundancy at a higher level (with replicas).

RAID0: hardware, with sliced drives (all drives are the same) give optimal speed multiple data dirs: software, can not be reverted, config overhead if disk sizes and speeds are unbalanced Many controllers support JBOD (concatenating different sized drives into one drive). I'd even prefere JBOD over multiple data dirs. Jörg -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
