Dear all We have two JBODs with 20 or 21 drives available per JBOD hooked up to a server. We are considering the following setups: RAIDZ2 made of 4 drives RAIDZ2 made of 6 drives The first option "wastes" more disk space but can survive a JBOD failure whereas the second is more space effective but the system goes down when a JBOD goes down. Each of the JBOD comes with dual controllers, redundant fans and power supplies so do I need to be paranoid and use option #1? Of course it also gives us more IOPs but high end logging devices should take care of that Thanks for any hint Thomas _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
