RAID 5
Data striping and stripe error correction information provided.
RAID 5 requires a minimum of 3 disks. RAID 5 can sustain one
failed disk.
RAID 6
Two independent parity computations must be used in order to
provide protection against double disk failure. Two different
algorithms are employed to achieve this purpose. RAID 6 requires
a minimum of 4 disks. RAID 6 can sustain two failed disks.
RAID 10
RAID 10 has high reliability and high performance. RAID 10 is
implemented as a striped array whose segments are RAID 1
arrays. It has the fault tolerance of RAID 1 and the performance of
RAID 0. RAID 10 requires 4 disks. RAID 10 can sustain two failed
disks.
RAID 50(N8900)
RAID 50 combines the straight block-level striping of RAID 0 with
the distributed parity of RAID 5. This is a RAID 0 array striped
across RAID 5 elements. It requires at least 6 drives.
RAID 60(N8900
)
RAID 60 combines the straight block-level striping of RAID 0 with
the distributed double parity of RAID 6. That is, a RAID 0 array
striped across RAID 6 elements. It requires at least 8 disks.
Edit RAID
On the RAID Information screen, press the Edit button to go to the RAID
Information screen.
Using Edit RAID, you can select RAID ID and the Spare Disk. .
WARNING
If the administrator improperly removes a hard disk that should not be
removed when RAID status is degraded, all data will be lost.
