RAID 5 increases performance by supporting concurrent accesses to the multiple
DDMs within each logical volume. Data protection is provided by parity, which is
stored throughout the drives in the array. If a drive fails, the data on that drive can
be restored using all the other drives in the array along with the parity bits that
were created when the data was stored.

RAID 6 overview

RAID 6 is a method of increasing the data protection of arrays with volume data
spread across multiple disk drives. The DS8000 series supports RAID 6 arrays.

RAID 6 increases data protection by adding an extra layer of parity over the RAID
5 implementation. By adding this protection, RAID 6 can restore data from an
array with up to two failed drives. The calculation and storage of extra parity
slightly reduces the capacity and performance compared to a RAID 5 array. RAID
6 is suitable for storage using archive class DDMs.

RAID 10 overview

RAID 10 provides high availability by combining features of RAID 0 and RAID 1.
The DS8000 series supports RAID 10 arrays.

RAID 0 increases performance by striping volume data across multiple disk drives.
RAID 1 provides disk mirroring, which duplicates data between two disk drives.
By combining the features of RAID 0 and RAID 1, RAID 10 provides a second
optimization for fault tolerance.

RAID 10 implementation provides data mirroring from one DDM to another DDM.
RAID 10 stripes data across half of the disk drives in the RAID 10 configuration.
The other half of the array mirrors the first set of disk drives. Access to data is
preserved if one disk in each mirrored pair remains available. In some cases, RAID
10 offers faster data reads and writes than RAID 5 because it is not required to
manage parity. However, with half of the DDMs in the group used for data and
the other half used to mirror that data, RAID 10 disk groups have less capacity
than RAID 5 disk groups.
