Intel Rapid Storage
The Intel Rapid Storage technology supported allows you to
create a RAID 0 and RAID 1 set using only two identical hard
disk drives. The Intel Rapid Storage technology creates two
partitions on each hard disk drive to create a virtual RAID 0
and RAID 1 sets. This technology also allows you to change
the hard disk drive partition size without losing any data.
RAID 10
RAID 10 is a striped confi guration with RAID 1 segments
whose segments are RAID 1 arrays. This confi guration has the
same fault tolerance as RAID 1, and has the same overhead
for fault-tolerance as mirroring alone. RAID 10 achieves high
input / output rates by striping RAID 1 segments. In some
instances, a RAID 10 confi guration can sustain multiple simul-
taneous drive failure. A minimum of four hard disk drives is
required for this setup.
RAID 5
RAID 5 stripes both data and parity information across three or
more hard disk drives. Among the advantages of RAID 5 confi -
guration include better HDD performance, fault tolerance, and
higher storage capacity. The RAID 5 confi guration is best sui-
ted for transaction processing, relational database applications,
enterprise resource planning, and other business systems. Use
a minimum of three identical hard disk drives for this setup.
