Chapter 1: Introduction to the LSI MegaRAID Software Utility
RAID 60
RAID 60 combines the features of RAID 6 and RAID 0. RAID 60 implements distributed parity (two independent parity bloks per stripe in a RAID set) and disk striping.The dual parity allows RAID 6 to survive two drive failures in each RAID 6 set without losing data. RAID 60 requires at least 8 drives. The following illustration provides a visual example of a RAID 60 virtual drive group.
Note: In the following RAID 6 illustration, the P drives represent the RAID 5 parity scheme. The Q drives represent the second set of parity drives.
