RAID Configuration

On the RAID Information screen, press the Config button to go to the RAID Configuration screen. In addition to RAID disk information and status, this screen lets you make RAID configuration settings.

For more information on RAID, see

Appendix C: RAID Basics.

RAID Level

You can set the storage volume as either None, JBOD, RAID 0, or RAID 1. RAID configuration is usually required only when you first set up the device. A brief description of each RAID setting follows:

RAID Levels

Level

Description

None

There is no existing storage volume.

JBOD

The storage volume is a single HDD with no RAID support. JBOD

 

requires a minimum of 1 disk.

RAID 0

Provides data striping but no redundancy. Improves

 

performance but not data safety. RAID 0 requires a minimum of

 

2 disks.

RAID 1

Offers disk mirroring. Provides twice the read rate of single

 

disks, but same write rate. RAID 1 requires a minimum of 2

 

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.

Disk Settings

Using Disk Settings, you can select stripe size, choose which disks are RAID disks.

Disk Settings

Item

Description

RAID

Check the boxes of the hard drives you wish to add to the

 

storage 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.

Create RAID

Press this button to configure a file system and create the RAID

 

storage volume.

Remove

Click to remove the RAID volume. All user data, snapshot, and

 

Target USB data will be removed.
