Chapter 1 Introduction
GV-NAS System is a Linux-based, network-attached storage device designed to store GV-IP
Camera recordings. GV-NAS System features RAID to ensure data security, rendering data
recovery possible. Allowing access from multiple users over multiple platforms (mobile
devices and desktop), user accessibility is customizable, keeping your data secure.
Management over a mass number of GV-IP Cameras is made easy with GV-Edge Recording
Manager, which provides an integrated interface where you can assign recordings to the
designated folder in GV-NAS Systems.

1.6 Installing the Hard Disks
The GV-NAS System’s disk drives are hot-swappable. You can install or replace hard drives
while the system is running. Follow the steps below to install a hard disk.
1. Press and pull out the disk holder. For GV-NAS4008/4016, the top of the disks should
face the right.
Figure 1-4 Two-Bay GV-NAS System Figure 1-5 Four-Bay GV-NAS System
2. Remove the clips on both sides.
Figure 1-6
3. Put the hard drive into the disk holder. Your hard disk should fit perfectly with the
connector pins facing the back.

Chapter 2 Getting Started
2.1 Looking Up the IP Address
By default, the IP address of GV-NAS System is assigned by the DHCP server when the
system is connected under a LAN environment. To find the IP address:
look up from the system’s LCD panel, or
browse for the device using the GV-NAS System Utility included in the software CD
2.2 Accessing the GV-NAS System
1. Find the system’s IP address from the LCD panel or using the GV-NAS System Utility.
For details, see 2.3 The GV-NAS System Utility.
2. Type the IP address into your Web browser and press Enter. This page appears.
Figure 2-1
3. Type the user name, password and the verification code to log in. The default user name
and password are both admin.
Note: If the GV-NAS System is installed behind a firewall or router, you may need to open
these default ports: HTTP port 80, FTP port 21, Ajaxplorer port 8090, Web Server port 8060,
Cloud Printing Service port 9100 and E-mail notification port 465 (for example: Google’s
SMTP).

12
2.3 The GV-NAS System Utility
You can also use the utility software included on the software CD to find the IP address.
1. Execute the file GV-NAS System Utility.exe. This dialog box appears.
Figure 2-2
2. Click Search to start searching the GV-NAS System under the same LAN. This dialog
box appears, showing the devices found and the network settings (IP address).
Figure 2-3
3. If your device does not show up, click Search again to browse again.

4. To configure the GV-NAS System’s network settings, device date and time, click Setup
and type the password.
Figure 2-4
Note: This setup will take you through the basic configurations of the device without an
Internet browser. Be advised the system must have at least one formatted volume in order to
proceed or this window will appear:
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

2. 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
3. To create RAID, you have two options:
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.
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
