Next year i'll start with our first production cluster. I'll put on that many VMs images (XenServer, ProxMox, ...). Currently I have 3 SuperMicro 6028R-E1CR12T to be used as storage nodes. I'll put 2 more 10GbT cards on each. Primary goal is to have MAXIMUM data redundancy and protection. we can live with not top-notch performances but data protection must be assured all the time in all conditions. Some questions: 1) should I create any raid on each server? If yes, which level and how many? - 4 RAID-5 with 3 disks each ? With this i'll create 4 bricks on each server - 6 RAID-1 with 2 disks each ? With this i'll create 6 bricks on each server (but space wasted is too high) - 2 RAID-6 with 6 disks each? With this i'll create 2 bricks on each server 2) Should I use standard replication (replicate 3) or EC ? 3) Our servers has 2 SSD in the back. Can I use this as tiering ? 4) Our servers has 1 SSD inside (not hotplug) for the OS. What would happens in case of a crash of this SSD ? Is gluster able to recover the whole failed node ? _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-users
