What does RAID-DP stand for, and what protection does it provide?

Explanation:
RAID-DP stands for Dual Parity RAID. It adds a second parity block across the disks in a RAID group, so the array can survive two simultaneous disk failures. With enough disks, you can lose any two drives and still reconstruct the missing data using the two parity sets, which is the same level of protection as RAID 6. It won’t protect against more than two failures, and the protection is within a single RAID group rather than across multiple groups.
