Is there any advantage in using Oracle partitioning with RAID 5?
Partitioning and RAID 5 are two independent and different concepts. Partitioning (spliting a large table or index into subsets) is typically done for either manageability or availability reasons. For example, you can put each partition on a different physical disk, so if a disk fails you lose only one partition. RAID 5 can be implemented in hardware or software to protect data from media or a disk failure. In a RAID 5 disk group, parity data is calculated and spread arcoss all the drives. In case of media or a disk failure, the RAID 5 group can still function in degraded mode based on the parity information. RAID 5 is good for read intensive, but not write intensive applications. There’s no problem mixing partitioning and RAID 5.
