Re: [zfs-discuss] zfs on top of 6140 FC array
Depends on what benefit you are looking for. If you are looking ways to improve redundancy you can still benefit from ZFS a) ZFS snap shots will give you the ability to withstand soft/user errors. b) ZFS checksum... c) ZFS can mirror (synch or async) a 6140'lun to an other storage for increased redundancy d) You can put an other level of raid over 6140's internal raid to increase redundancy e) Use ZFS send recieve to backup data some other place.

AFAIK this array does have internal redundant paths up to the disk connection. justin Multipathing and redundant controllers in the 6140 gets you HARDWARE redundancy, so you are (less) susceptible to a piece of hardware killing your setup. You should _still_ use ZFS redundancy to get all the other benefits, from self-healing to true block integrity, none of which is provided by the hardware (any hardware, for that matter). -- Erik Trimble Java System Support Mailstop: usca22-123 Phone: x17195 Santa Clara, CA Timezone: US/Pacific (GMT-0800) ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
