The MegaRAID 320-4X supports disk arrays using the
following RAID levels:
•
RAID 0 (Data striping): Stripes data across all disks in
the array, enabling very fast data throughput. There is no
data redundancy. All data is lost if any disk fails. (1
–
30
disk drives)
•
RAID 1 (Disk mirroring): Writes data simultaneously to
two disks, providing complete data redundancy if one disk
fails. The maximum array capacity is equal to the available
size of the smaller of the two hard drives. (2 disk drives)
•
RAID 5 (Disk striping with distributed parity): Stripes
data across all disks in the array. Part of the capacity of
each disk stores parity information that reconstructs data if
one disk fails. Provides good data throughput for
applications with high read request rates. (3–30 disk drives)
•
RAID 10 (RAID 1 and RAID 0 in spanned arrays): Uses
mirrored pairs of disks to provide complete data
redundancy. Provides high data throughput rates. (4–30
disk drives)
•
RAID 50 (RAID 5 and RAID 0 in spanned arrays): Uses
both parity and disk striping across multiple disks to
provide complete data redundancy. Provides high data
throughput rates. (6–30 disk drives)
