I'm partial to 8 disk RAID 10 volumes for datafiles. how about if you create one on each tray for datafiles and stripe across those?
you could then use the remaining 7 drives per tray for 4 disk RAID 10 and 2 disk RAID 1 vols with a hot spare. Aim for a 1 MB stripe on the 8 disk RAID 10 vols, as your OS supports that for a max IO size and based upon your db_block_size (or the block size for each tablespace) and the dbfmbrc oracle should be able to issue 1 MB read requests - in theory.

kinda cool having the volume sizes increase by powers of 2.

Are you planning on allocating any LUNs to ASM? Are you planning on reserving any LUNs for backup sets?

kudos on planning to run a new version of clusterware that hasn't even been released yet - you are most brave. Are you going to run 10g R2 on that as well?
