How to create JBOD with Areca controller, it is very easy .
Since redundancy and failure maintain by ceph itself , it is better to have disks with JBOD instead of Raid when integrated with CEPH.
To use Areca in JBOD:
– enter RAID setup by pressing Tab/F3 when the Areca BIOS bootstrap tells you so
– remove all RAID sets including any passthrough disks
– go to “raid functions” menu and choose “JBOD/RAID mode” and set it to JBOD instead.
– go back to main menu and press F10 to reboot
System Controls -> system configuration.
