which ASM storage configuration strategy would provide best I/O throughput

I have 14 disk EMC array. I am planning to create 2 RAID Group ( 8 disk + 6 disk).

Option #1: Create two LUNS one each for two RAID GROUPs. And then  create two disk groups utilizing one LUN each.

Option#2: Create 8 and 6 LUNS for each physical disk in RAID GROUP1 and RAID GROUP 2 respectively.

                   Then create DISKGROUP1: using all 8 LUNS and DISK GROUP2: using all 6 LUNS

Option#3: Create 8 and 6 LUNS for each physical disk in RAID GROUP1 and RAID GROUP 2 respectively.

                   Then partition 8 LUNS using OS level partitioning tool (for example, fdisk) into 16 partition. And then create 16 ASM Disks ( logical ASM disks using ./oracleasm createdisk command).
