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. 
WARNING 
If the administrator improperly removes a hard disk that should not be 
removed when RAID status is Degraded, all data will be lost. 
 
 
 
RAID Settings 
Using RAID Settings, you can select stripe size, choose which disks are RAID 
disks or the Spare Disk, as well as enter a name for each disk.

Item Description 
RAID 
Check the boxes of the hard drives you wish to add to the 
storage volume. 
Master RAID 
Check a box to designate this as the Master RAID volume. See 
the 
NOTE
 below for more information. 
Disk No. 
Number assigned to the installed hard disks. 
Capacity (MB) 
Capacity of the installed hard disks. 
Model 
Model number of the installed hard disks. 
Status 
Status of the installed hard disks. 
Member 
If this is checked, current hard disk is a part of a RAID volume. 
Spare 
If this is checked, current hard disk is designated as a spare for 
a RAID volume. 
Stripe Size 
This sets the stripe size to maximize performance of sequential 
files in a storage volume. Keep the 64K setting unless you 
require a special file storage layout in the storage volume. A 
larger stripe size is better for large files. 
Used Percentage 
The percentage of the RAID volume that will be used to store 
data. 
Apply 
Press this button to configure a file system and create the RAID 
storage volume. 
Remove 
Click to remove the RAID volume. All user data, iSCSI, and 
Target USB data will be removed. 
Back 
Press this button to exit without saving changes. 
Expand 
Press this button to configure a file system and create the RAID 
storage volume. 
Migration 
Press this button to migrate RAID level. 
Creating a RAID 
To create a RAID volume, follow the steps below: 
 
1.  On the RAID List screen, click New
 
2.  On the RAID Configuration screen, set the RAID storage space as JBOD
RAID 0RAID 1RAID 5RAID 6, or RAID 10 — see 
 for a detailed description of each. 
 
3.  Specify a RAID ID.
