Technical Support
RAID 1 (drive mirroring): Data is written simultaneously to both drives in the drive
group, providing complete data redundancy if one drive fails. RAID 1 supports an
even number of drives from 2 to 32 in a single span.
RAID 5 (drive striping with distributed parity): Data is striped across all drives in
the group. Part of the capacity of each drive stores parity information that
reconstructs data if a drive fails. RAID 5 provides good data throughput for
applications with high read request rates.
RAID 6 (drive striping with distributed parity across two drives): Data is striped
across all drives in the group and two parity drives are used to provide protection
against the failure of up to two drives. In each row of data blocks, two sets of parity
data are stored.
RAID 00 (data striping across RAID 0 drive groups): RAID 00 is a spanned drive
group that creates a striped set from a series of RAID 0 drive groups.
RAID 10 (RAID 1 and RAID 0 in spanned groups): RAID 10 uses mirrored pairs of
drives to provide complete data redundancy. RAID 10 provides high data
throughput rates.
RAID 50 (RAID 5 and RAID 0 in spanned groups): RAID 50 uses both parity and
drive striping across multiple drives to provide complete data redundancy. RAID 50
provides high data throughput rates.
RAID 60 (RAID 6 and RAID 0 in spanned groups): RAID 60 uses both distributed
parity across two parity drives and drive striping across multiple drives to provide
complete data redundancy and high fault tolerance.

Software Suite CD for more information about RAID levels
