Data Striping with Parity implements RAID Level 5 functionality at the software level. With this, a volume can be spread between three or more physical disks with parity information distributed across all disks. In the event of a single disk device failure, the parity information can be used to keep the volume and system running until the system administrator can rectify the problem, greatly reducing the chance of disk-related server failure.
Data Mirroring/Duplexing allows for the physical duplication of disk devices in real-time, providing for instantaneous recovery in the event of a failure. With mirroring, you use one disk controller for both mirrored drives. With duplexing, you use two disk controllers, one for each mirror drive, which prevents a controller-related problem from causing a system crash.
