RAID
Several fault tolerant configurations keep data available and servers running while drives are being
replaced – RAID levels that offer fault tolerance include:
RAID 50 (RAID 5+0)
RAID 50 (RAID 5+0)RAID 50 (RAID 5+0)
RAID 50 (RAID 5+0)
protects against failure of one drive (and failure of particular multiple
drives). RAID 50 is a nested RAID method that uses RAID 0 striping across RAID 5 arrays. RAID 50
tolerates one drive failure in each spanned array without loss of data. RAID 50 requires less
rebuild time than single RAID 5 arrays RAID 50 requires a minimum of six drives.
RAID 60 (RAID 6+0)
RAID 60 (RAID 6+0)RAID 60 (RAID 6+0)
RAID 60 (RAID 6+0)
allows administrators to split the RAID 6 storage across multiple external
boxes. RAID 60 requires a minimum of eight drives. RAID 60 is a nested RAID method that uses
RAID 0 block-level striping across multiple RAID 6 arrays with dual distributed parity. With the
inclusion of dual parity, RAID 60 will tolerate the failure of two disks in each spanned array
without loss of data.

: Allocates the equivalence of two parity drives across multiple drives and allows
simultaneous write operations.Distributed Data Guarding (RAID 5): Allocates parity data across
multiple drives and allows simultaneous write operations.Drive Mirroring (RAID 1 and 1+0 Striped
Mirroring): Allocates half of the drive array to data and the other half to mirrored data, providing
two copies of every file.

Dual domain SAS creates redundant pathways from servers to storage devices. The redundant paths
created by these configurations reduce or eliminate single points of failure within the storage network.
This provides increased levels of high availability with redundant paths from the controller to the drives.
Dual domain SAS implementations make it possible to tolerate host bus adapter (HBA) failure, external
cable failure, expander failure, failure in a spanned disk (JBOD) environments.
