8-bay raid station 22
11.4 R30 mode
Function:
The R30 mode adds fault tolerance to drive striping by adding parity information to the
data. R30 mode dedicates the equivalent of two drives (SYS1 and SYS2) for storing
parity information and to stripe these again. The data and parity information is arranged
on the drive array so that parity is written to two drives. The following example illustrates
how the parity is rotated from drive to drive.
