  • Page 76: Raid 5Dp

    RAID 1+0 provides data redundancy and good performance. However, the performance is achieved by using a less efficient technique of storing redundant data called “mirroring.” Mirroring maintains two sets of the data: a primary set and a backup set, or “mirror”, of the primary set. Therefore, half of the disk space is consumed by redundant data.

    Also, if a third disk in the LUN fails while in a degraded state, parity can no longer be used and all data in the LUN becomes inaccessible. Figure 3 is an example showing the distribution of user data and parity data in a RAID 5DP configuration.
