RAID 10 Disk Volume
RAID 10 combines four or more disks in
a way that protects data against loss of
non-adjacent disks. It provides security
by mirroring all data on a secondary set
of disks while using striping across each
set of disks to speed up data transfers.
RAID 10 requires an even number of
hard drives (minimum 4 hard drives).
The storage capacity of RAID 10 disk
volume is equal to (size of the smallest
capacity disk in the array) * N/2. N is
the number of hard drives in the
volume.

You can perform online RAID capacity expansion (RAID 1, 5, 6, 10) and online RAID level
migration (single disk, RAID 1, 5, 10), add a hard drive member to a RAID 5, 6, or 10
configuration, configure a spare hard drive (RAID 5, 6, 10) recover a RAID configuration on
this page.
Caution: When the hard drive synchronization is in process, do NOT turn off the
