Figure 2-5

2.4 Creating RAID

GV-NAS System supports single disk formatting, linear (JBOD), RAID 0, RAID 1 and RAID 5 setup. Follow the steps below to format or create RAID to your disk drives.

Note: RAID 5 is only supported by GV-NAS4016.

1. Upon entering the user interface, you are prompted to format the inserted hard disks. The applications (except the Disk & RAID Management) are only accessible with at least one formatted disk.

Figure 2-6

1. Click OK on the warning message This window appears. The Single / RAID column indicates the status of the mounted hard disks. In this case, they have not been formatted yet.

Figure 2-7

1. To create RAID, you have two options:

2. Automatic setup: RAID is created based on the number of inserted disks. A single disk will be formatted individually; two disks will be formatted to RAID 1; three disks or more will be formatted to RAID 5. Click One Click RAID Creation to start this setup.

3. Manual setup: Manually select the hard disk drives and then click Single Disk Volume, Linear Volume, RAID 0, RAID 1 or RAID 5.

Figure 2-8

Data Storage Description
Single Disk Volume	The selected disk drive will be formatted individually.This mode requires only one disk at a time.If a 1 TB and a 3 TB disk are formatted individually, forming two logical disk volumes, at a total storage space of 4 TB.
Linear Volume (JBOD)	Two or more disk drives are combined to form one logical volume.This mode requires two or more disks at a time.The storage capacity will be the total disk space of all disk drives.For example, a 1 TB and a 3 TB disk will form one logical disk volume with 4 TB storage capacity.
RAID 0 Mode	The storage is striped in which data is spread evenly across two or four drives to provide a better system performance.This mode requires two or four disks at a time.The storage capacity will be the capacity of the smallest disk drive times the number of disk drives. For example, a 1 TB and a 3 TB disk will form one logical disk volume with 2 TB storage capacity (1 TB x 2 disks = 2 TB).
RAID 1 Mode	The storage is mirrored in which the data is saved to one drive and duplicated to another drive. This mode provides data protection when one hard drive fails.This mode requires at least two disks.The storage capacity will be the capacity of the smallest disk drive. For example, a 1 TB and a 3 TB disk will form one logical disk volume with 1 TB storage capacity.
RAID 5 Mode	This mode offers data protection while minimizing storage waste. Data are carefully arranged and spread evenly into all the RAID 5 drives, in case when one drive fails, data can be rebuilt using the remaining working drives.This mode requires at least 3 disks. Note this mode only allows one drive failure. If more than one drive fails, data will not be recoverable.The storage capacity will be (the size of the smallest drive) x (number of drives -1). For example, if you have three 2 TB drives and one 1 TB drive, the total capacity will be 1 TB x (4 - 1) = 3 TB. It

is recommended to use the three 2 TB drives to form RAID 5 and the 1 TB drive as a single volume. In this case, you will get 2 TB x (3 - 1) = 4 TB RAID 5 system and another 1TB single volume. This organization provides a 5 TB storage space as opposed to the 3 TB capacity. The rule of thumb is to use drives of the same capacity for RAID system as much as possible.

1. The formatting starts immediately. The system reboots when the formatting is completed.
2. Optionally configure the disks from the Disk & RAID Management window.

Figure 2-9

A. To remove a formatted volume, select a volume from the Mode column and click Remove the selected volume.
B. To remove a disk from a RAID group, select a disk from the Hard Disk Drive column and click Remove Disk.
C. To add another disk to a RAID group, click Add Disk(s) to RAID.

IMPORTANT:

1. Depending on the size of the hard disks, GV-NAS System may take varying amount of time to establish and rebuild RAID.
2. Make sure the power supply is stable during the formatting. Power failure during formatting may cause permanent damage to the system, rendering the device unusable.
