This is the case where I don't understand Sun's politics at all: Sun doesn't offer really cheap JBOD which can be bought just for ZFS. And don't even tell me about 3310/3320 JBODs - they are horrible expansive :-( If Sun wants ZFS to be absorbed quicker it should have such _really_ cheap JBOD. przemol _______________________________________________ zfs-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
