best way and best performance

Hi all,
I have two storadge 3510 Fc .. with 12 disks 146Gb ..total 1752Gb each storadge. I need to use about 1.4 Tb of it. and want RAID1 ..

I need 13 mount points ..
So question:
for best performance and redundjancy how I must do it.
create 13 logical drives on each stordge with same size and mirror them and use directly ? or do it with soft partition?

Thanks for help.
