We use RAID 5 on Digital Unix 3.2C with the SWXCR RAID. One full RAID5 partition is used for SYSTEM tablespace, data tablespace, temporary tablespace, rollback tablespace, control files and log files. However, copies of the control files are maintained on other disks also. If you are putting the disks for Oracle use, you are better off putting the disks on the RAID5 as it can keep the system going even if you lose one disk.
