Parity Protection (RAID 3 and RAID 5)
The XOR engine in the RAID controller generates parity
block. In RAID 3 mode, parity block will be stored in the
same hard disk drive. In RAID 5 mode, parity block will be
spread over all of the different hard drives.
The RAID controller will also make use of the same size disk
space in each hard disk under RAID 3 / RAID 5 condition.
Failure in a hard disk will cause the RAID
controller to enter into degraded mode. Host
controller still could rear/write data thru the
RAID normally without knowing any defects.
Users have to replace the defective hard disk. The RAID
controller will then enter into online-auto-rebuild mode
automatically.
