Re: suggestions on striping

Sounds cool to me. Granted our boxes are way older than yours, but we use six disks per chain, mirror each disk to its opposite number on another chain *and controller*, then stripe six ways across the disks making 2 GB stripes. Each stripe set (6+6 disks) is used for one tablespace's files.
