Figure 3-8. Striping Over Mirrored Disk Groups
RAID 10 Characteristics:
• Groups n disks as one large virtual disk with a capacity of ( n /2) disks, where
n is an even integer.
• Mirror images of the data are striped across sets of
physical disks . This
level provides redundancy through mirroring.
• When a disk fails, the virtual disk still works. The data is read from the
surviving mirrored disk.
• Improved read performance and write performance.
• Redundancy for protection of data.
