[b]Given[/b]: A Solaris 10 u3 server with an externally attached disk array with RAID controller(s)
[b]Question[/b]: Is it better to create a zpool from a [u]single[/u] external LUN on an external disk array, or is it better to use no RAID on the disk array and just present individual disks to the server and let ZFS take care of the RAID? [b]Example[/b]: I have a Solaris 10 server with an attached 3320 disk array and want to use ZFS instead of UFS. Should I create a single RAID protected LUN on the 3320 and build a single disk ZFS pool on it, or should I setup each disk in the 3320 as an "NRAID" (aka individual disk) to be used by the server in a multi-disk zfs pool? [b]Thoughts[/b]: Performance, reliability, mobility? Considerations: With hardware raid, zfs is dependent upon the raid controllers. If using individual disks, the disks may be put into another disk array and imported..? If I create one or more RAID groups on the 3320 and make a single disk zpool on each RAID disk, I could still use the 3320 "hot spare" feature to help protect from a disk failure..?
