For 3 servers with 12 disks each, I would do Hardware RAID0 (or madam if you don’t have a RAID card) of 3 disks. So four 3-disk RAID0’s per server. I would set them up as Replica 3 Arbiter 1 server1:/brickA server2:/brickC server3:/brickA server1:/brickB server2:/brickD server3:/brickB server2:/brickA server3:/brickC server1:/brickA server2:/brickB server3:/brickD server1:/brickB server3:/brickA server1:/brickC server2:/brickA server3:/brickB server1:/brickD server2:/brickB The benefit of this is that you can lose an entire server node (12 disks) and all of your data is still accessible. And you get the same space as if they were all in a RAID10. If you lose any disk, the entire 3 disk brick will need to be healed from the replica. I have 20GbE on each server so it doesn’t take long. It copied 20TB in about 18 hours once. _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-users
