Oracle on RAID - Thanks

To whomever posted the link to Gaja's paper Implementing RAID on Oracle - thank you. I previously had printed and passed this article on to my system administrator -- no reaction. But yesterday he was building our new Sun system with all the latest features, and was so excited about the paper that he asked for a second copy to share with his junior sys admin. He stopped building the system to take a day to study Gaja's paper in detail.

   Of course, the Sun engineer is saying "our new RAID 5 is just as fast as RAID 10 because we stripe parity across all disks".

    Since this will be an OLTP system, I am planning on an 8K Oracle block size, unless anyone has better information on how to pick a block size. Apparently there are a lot of storage system parameters you can optimize, but they are based on the Oracle block size.
