Add a RAID Group
To add a RAID group, first specify the
RAID level
. The server supports RAID 0,
RAID 1 and RAID 5.
Second, select the hard disk drives in the
Available HD(s)
sub-window, then click the
Add->
button to move them into the
RAID
Group Members
sub-window.
Last, click the
Setup
button to create the
RAID with the selected HD drives as its
members.
RAID 0
RAID level 0 is disk striping only, which
interleaves data across multiple disks for
better performance. It does not provide
safeguards against failure.
RAID 1
RAID level 1 uses two hard drives. It keeps
identical copies of data on the two hard
drives. If one hard drive fails, the RAID can
still operate without data loss. It offers the
highest reliability, but doubles storage cost.
Two hard drives can only have the capacity
of one.
RAID 5
RAID level 5 uses three or more hard
drives. Data, together with the parity bits,
are striped across the hard drives. It is a
tradeoff between fault tolerance and
storage cost. RAID 5 can operate normally
with one hard drive corrupted, but only
have the capacity of (N-1) hard drives,
where N is the number of hard drives being
grouped.
