I package up 5 or 6 disks into a RAID-5 LUN on our Sun 3510 and 2540 arrays.
Then I use ZFS to RAID-10 these volumes. Safety first! Quite frankly I've had ENOUGH of rebuilding trashed filesystems. I am tired to chasing performance like it's the Holy Grail and shoving other considerations aside. A ZFS mirror pair can know when there's a bad block and get it from the other one, which is something you will not get with HW RAID. When Sun starts selling good SAS JBOD boxes equipped with appropriate redundancies and a flash-drive or 2 for the ZIL I will definitely go that route. For now I have a bunch of existing Sun HW RAID arrays so I make use of them mainly to make sure I can package LUNs and that assigned hot-spares are used to rebuild the LUNs when needed.
