Urgent: How to setup raid1+0 for SE 3510 FC array

Hi,

I have some urgent questions: I want to set up raid 1+0 with only ONE LUN number for our SE 3510 FC array. After reading thru the 'raid firmware user's guide', I figured out that there possibly two methods to set it up:

1) create one big raid1 logical drive with 12 physical disks and assign this logical drive a LUN number;

2) create 6 raid1 logical drives with 2 disks mirrored each and create one logical volume on top of those 6 raid1 logical drives then assign logical volume a LUN number

My questions are:

Are they right ways to create raid1+0? Are those 2 methods same? Which one is better? Or is there any other way to create raid1+0?

Thanks,
