Let's assume a small cluster made by 3 servers, 12 disks/bricks each.
This cluster would be expanded to a maximum of 15 servers in near future.

What do you suggest, a JBOD or a RAID? Which RAID level?

I setup my much smaller cluster with ZFS RAID10 on each node.

- Greatly increased the iops per node

- auto bitrot detection and repair

- SSD caches

- compression clawed back 30% of the disk space I lost to RAID10.
