Hello all, I have been doing some research into possible alternatives to our OpenSolaris/ZFS/Gluster file server. The main reason behind this is, due to RedHat's recent purchase of Gluster, our current configuration will no longer be supported and even before the acquisition, the upgrade path for the OpenSolaris/ZFS stack was murky at best. The current servers in question consist of a total of 48, 2TB drives. My thought was that I would setup a total of 6 RAID-6 arrays (each containing 7 drives + a spare or a flat 8 drive RAID-6 config) and place LVM + XFS on top of that. My questions really are: a) What is the maximum number of drives typically seen in a RAID-6 setup like this? I noticed when looking at the Backblaze blog, that they are using RAID-6 with 15 disks (13 + 2 for parity). That number seemed kind of high to me....but I was wondering what others on the list thought. b) Would you recommend using any specific Linux distro over any other? Right now I am trying to decide between Debian and Ubuntu....but I would be open to any others...if there was a legitimate reason to do so (performance, stability, etc) in terms of the Raid codebase.
