I happen to have some 3510, 3511 on SAN, and older 3310 direct-attach arrays around here.
Also some newer 2540 arrays. Our preferred setup for the past year or so, is 2 arrays available to the server. >From each array make 2 LUNS available. Take these LUNs on the server and ZFS them as RAID-10. The implication of this is the the existing hardware RAID was leveraged for it's buffering and it's smarts in hot-sparing failed drives to the right LUN. Do you really want a drive in a 2nd chassis being a hot spare to drives in another chassis? Until ZFS gives a clean way to designate hot-spares go only with this group of disks and not others you have a dependency problem. How big of a deal this is arguable. As is for example our preference to "waste" 2 arrays in this manner to gain the redundancy that an entire drive chassis can fail without interrupting ops. YMMV. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
