RAID 6 Disk
Volume
RAID 6 disk volume is ideal for important data protection.
To create a RAID 6 disk volume, a minimum of 4 hard disks
are required. The total capacity of RAID 6 disk volume
equals the size of the smallest capacity disk in the array x
(number of hard disks -2). It is recommended that you use
same brand and same capacity hard drive to establish the
most efficient hard drive capacity.
RAID 6 can survive 2 drives failure and system can still
operate properly.
NOTE
To install a disk when the server is on, make
sure the disk volume is in “degraded” mode. Or wait
for two long beeps after the disk crash, and then
insert the new disk.
RAID 5, RAID 6
Read-only Mode
The drive configuration enters read-only mode in the
following occasions:
•
2 drives are damaged in RAID 5
•
3 drives are damaged in RAID 6
The drives in the above configurations are read-only. It is
recommended to re-create new drive configuration in
such case.
