RAID0
RAID1 RAID1 RAID1 RAID1 RAID1 RAID1
For example, if disk failure occurs in dierent drive groups, a RAID10 conguration can
tolerate multiple drive failures. In each RAID1 drive group, data is mirrored to a counterpart
disk drive. Data remains intact if one disk drive should fail in each drive group.
Consistency Check
The consistency check operation veries the correctness of the data in virtual drives that use
RAID levels 1, 5, 6, 10, 50, and 60. RAID0 does not provide data redundancy. In a system with
parity, check consistency means calculating the data on one drive and comparing the results to
the contents of the parity drive.
