3.5 Network Settings
3.5.1 TCP/IP Configuration
ND23000
NAS-3000/ NAS-4010
26
Configuration of Network Interfaces
Note that ND23000 provides single port only and does not support fail over, load
balance or standalone functions.
ü Fail Over
The system supports the configuration of multiple network interfaces, which
enables you to perform Fail Over or Load Balance functions. Fail over
ensures server availability to the network. If the primary port is
disconnected due to a hardware or cable problem, the secondary port will
replace its network identity. If the failed port resumes the network
connection, it will also resume the role as the primary interface.
ü Load Balance
In load balance mode, the transmission load is distributed among aggregated
network ports. An intelligent software adaptive agent will repeatedly analyze
the traffic flow from the server and distribute the packets based on the
destination address. Load balance can only occur on Layer 3 routing
protocols (IP or NCP IPX). Multicast/Broadcast and non-routing protocols,
such as NetBEUI and Microsoft IPX, are transmitted over the primary port.
27
ü Standalone
Standalone settings enable each port to have a unique IP, which allows users
on different network areas to share one NAS and maintain their
independence from one another in the network. When using this mode, fail
over cannot be used and only one port can be configured as DHCP server.
28
Network Speed
Network speed settings provide an advanced option for configuring network speed.
You can select auto-negotiation to determine network speed automatically. It is
recommended to use the default setting.
You can configure TCP/IP settings in the following modes:
· Obtain IP address settings automatically via DHCP
If your network supports DHCP, NAS will automatically use DHCP protocol to
retrieve the IP address and related information.
· Use static IP address
To use fixed IP address for network connection, enter the IP address, subnet
mask, and default gateway.
Primary DNS Server: Enter the IP address of primary DNS server that
provides DNS service for NAS in external network.
Secondary DNS Server: Enter the IP address of secondary DNS server that
provides DNS service for NAS in external network.
29
You can also configure the following settings:
ü Enable DHCP server
If there is no DHCP server on the network, you can enable this option to
provide IP address settings to the clients.
Start IP address
The first IP address to be dynamically allocated for DHCP service.
End IP address
The last IP address to be dynamically allocated for DHCP service.
Lease time
Define the lease time for the dynamic IP address.
Primary DNS server/ Secondary DNS server
When the system allocates an IP address to your computer, the primary DNS
server address or secondary DNS server is also specified to it.
Note that if you do not assign at least a DNS server to DHCP service, while
there is no other DNS server specified by your PC, you may not be able to
access websites on the network.
30
3.5.2 Microsoft Networking
Enable file service for Microsoft networking: For users using Microsoft
Windows, enable this service to access the files on network share folders. Assign
a workgroup name. The name can be 15 characters long at maximum but must
not include the following:
" + = [ ] , ; / \ : | * ? < > . "
Note: The first character cannot be a period (.).
ü Standalone Server
Use local users for user authentication.
ü NT Domain Member
Use Microsoft NT domain for user authentication.
ü AD Domain Member
Use Microsoft AD domain for user authentication.
Ø Server Description: Describe NAS, e.g. administrator name, department,
or location of the server, for users to identify the server. Users using NAS
on the Microsoft Windows operating systems must enable Microsoft
Network Services.
31
Ø Workgroup: When configuring NAS as standalone server, specify the
workgroup the server belongs to. The workgroup is a computer group unit
in Microsoft Windows network for network sharing.
Ø Domain Name: Microsoft domain name. Enter the domain name when you
select NT domain or AD domain.
ü WINS server
If the local network has a WINS server installed, specify the IP address. NAS
will automatically register its name and IP address with WINS service. If you
do not want to enable WINS server support, or you do not have a WINS
server on your network, enter 0.0.0.0 in the field for WINS server IP address.
ü Domain Master
There is a unique Domain Master Browser for collecting and recording
resources and services available for each PC in the network or workgroup of
Windows. When there is already a domain master browser (Windows NT/
200x/ XP PC) in the network, there is no need to configure NAS as the domain
master.
When you find the waiting time for accessing Network Neighborhood too long,
it may due to failure of an existing master browser, or there is no master
browser available. If the reason is the latter one, you can check the box
Domain Master in this section to configure NAS as the master browser to
enhance the speed of accessing information on Network Neighborhood.
32
3.5.3 Apple Network
To use NAS on Apple MAC operating system, enable AppleTalk network support.
If your AppleTalk network uses extended networks, and is assigned with multiple
zones, assign a zone name to NAS. If you do not want to assign a network zone,
enter an asterisk (*) to use the default setting.
3.5.4 NFS Service
To use NAS on Unix/ Linux operating system computer or server, enable NFS
service. NAS supports NFS version 2.0 and 3.0. To correctly use NFS service,
assign a user’s UID and IP address. Go to NFS Settings in Users of User
Management for setup. When you have completed the configuration, login the
system as root and use mount command to connect to the network. You can
then login with other identities and access NAS using previous NFS settings.
33
3.5.5 NetWare Service
To use Novell Netware service, enable this option and enter the server name for
Netware network. The server will then operate in a manner similar to a Novell
NetWare 3.12 file server.
To configure more options for Netware service, enable Netware service and click
Advanced.
· Frame Type: If you have a Novell server on your local network, select the
same frame type as the server's.
· Internal Network Number: This is a unique number to identify the server on a
network. The system will set it to the IP address if Auto-configure option is
selected. Or you may enter a unique internal network number manually.
· External Network Number: This number identifies a logical network segment
on a network. The system can configure it automatically, or you can set the
external network number manually.
34
3.5.6 Web Service
To access files on NAS via web browser, enable Web File Manager. If NAS is
connected to the Internet and uses a valid IP address, you can access files on the
server by web browser from anywhere.
3.5.7 FTP Service
To download files from or upload files to NAS by using file transfer protocol (FTP),
activate FTP service.
35
3.5.8 Network Printer Service
NAS provides network printer service. You can configure a USB printer as the
network printer via NAS. To use this function, click “Enable network printer
service”. Enter the printer name and description (optional).
Printer Settings on Client Side
1. Connect NAS.
2. After correctly enabling a USB printer on the server side, a printer i con should
be shown in the share folder. Right click the item and click Open or Connect.
36
3. Install the printer driver.

3.6 Disk Configuration
ND23000 and NAS-3000 can accommodate two disks at maximum. NAS-4010
supports four disks at maximum. You can set the disk volume to the following
configurations:
1. Single Disk Volume
You can select to use a standalone disk. In case of disk crash, all data will be
lost.
2. RAID 5 Disk Volume (supported by NAS-4010 only)
Three or more hard disks can be teamed up to form a large-capacity RAID 5
disk group. This system will distribute and store data among its various
member disks as it is received. At the same time it uses an amount of space
roughly equivalent to a whole disk to store reference numbers with the same
elements. Should one of the disks in the group suffer some kind of damage,
you can shut down the computer and install a new disk, and the system will
restore the data on the new disk using the reference number. In addition, if
you have a system with four disks but use only three in RAID 5 group, the
fourth will serve as a backup disk. If one of the three disks is damaged the
system will automatically start using the spare disk without powering down
and changing the affected disk. Generally speaking, the capacity of a RAID 5
disk group is one disk’s worth of space less than the total rated capacity of
the group.
3. RAID 1 Mirroring Disk Volume
Mirroring Disk protects your data by automatically backing up the contents of
one disk onto the second disk of a mirrored pair. This protects your data if
one of the disks fails. However, the storing capacity is equal to a single disk,
as the second disk is used to automatically back up the first one. Mirroring
disk volume is suitable for personal or corporate use to store important data.
40
4. RAID 0 Striping Disk Volume
Striping disk combines two or more disks into one larger disk. It offers the
fastest disk access but it does not have any protection of your data if the
striped array fails. The disk capacity equals the number of disks in the array
times the size of the smallest disk. Striping disk is usually used to maximize
your disk capacity or for fast disk access but not for storing important data.
5. Linear Disk Volume
You can combine two or more disks into one larger disk. During file saving,
the file will be saved on physical disks sequentially but does not have a disk
failure file protection function. The overall capacity of linear disk is the sum of
all disks. Linear disk is generally used for storing large data and is not
appropriate to use for file protection of sensitive data.
41
By factory default, NAS is preset to one large RAID 0 disk (applicable for servers
with two or more disk volumes). To use other disk configurations, the settings
can be changed during the first Quick Configuration access.
You can also administer your disk volume in the following ways:
i. Create Disk Volume
ii. Delete Disk Volume
42
iii. Examine Disk Volume
ü Disk Volume Operation Report
This page shows the current status and information of disk volume
operation.
43
iv. Format Disk Volume
v. View Disk & Volume Status
44
vi. Snapshot Settings (Not available for ND23000)
Snapshot enables users to create a copy of disk volume as backup source.
The creation of snapshot will not modify the disk volume while any changes
made to the disk volume will not affect any formerly taken snapshots.
· Basic Snapshot Settings
To activate or disable a snapshot, go to Snapshot Settings of Disk
Configuration and click Basic. Enable snapshot support of the disk volume
before creating a snapshot.
To enable snapshot support for one or more volumes, select the item(s),
assign Repository Ratio and Maximum Count values and then click OK.
To disable snapshot support, unselect the item(s) and click OK. To undo
the changes, click Cancel and refresh the page.
Note:
1. To change Repository Ratio or Maximum Count of volume, disable its
snapshot support, click OK, and enable it again.
2. Disabling the snapshot support will automatically remove all snapshots
on the volume.
45
· Advanced Snapshot Settings
To set up when to warn about every snapshot's use status, set the
Snapshot Warning Threshold value and click OK. The default threshold to
log a warning message is when a snapshot is 90% full. Click Basic or
Cancel to return to the Basic Snapshot Settings page.
ü Create a Snapshot or a Schedule
In Snapshot Settings page, click Schedule to create, edit or delete a
snapshot schedule. Users can schedule an hourly, weekly or monthly
snapshot of the disk volume.

automatically for tape backup or remote replication.
In Remote Replication of System Tools, click New.
Check the box “Create a temporary snapshot for the replication” as shown
below:
50
3.7 User Management
The files on NAS can be shared among multiple users. For easier management
and better control of users’ access right, you have to organize users, user groups
and their access right control.
· Users
The system has created the following users by default:
Administrator
By default, administrator is a member of the administrator group and has
access to system administration. You cannot delete administrator.
Guest
When you use a non-registered user name to login, the server will recognize
the user as a Guest and will allow limited access. A guest does not belong to
any user group. You cannot delete the user Guest or create a password.
Anonymous
When you connect to the server by FTP service, you can use the name to login
as a guest. You cannot delete this user or change its password.
You can create a new user according to your needs. The following information
is required to create a new user:
51
ü User name
The user name must not exceed 32 characters. It is case-insensitive and
can contain double-byte characters, such as Chinese, Japanese, and
Korean except:
" / \ [ ] : ; | = , + * ? < > ` '
ü Password
The password must be 6~16 characters long. Avoid using codes that are
easily decipherable.
You can perform the following settings for users:
i. Create
ii. Create Multiple Users
iii. Change Password
iv. Create Private Network Share
v. Assign User Groups
vi. Quota Settings
vii. Delete
52
· User Groups
User group is a collection of users with the same access right to files or
folders. NAS has created the following user groups by default:
ü Administrators
All members of administrators group have the right to perform system
management. You cannot delete this group.
ü Everyone
All registered users belong to everyone group. You cannot delete this
group.
You can manage user groups with the following options:
i. Create
ii. Create Private Network Share
iii. Assign Users
iv. Delete
User groups name must not exceed 256 characters. It is case-insensitive
and can contain double-byte characters, such as Chinese, Japanese, and
Korean, except the following ones:
" / \ [ ] : ; | = , + * ? < > ` '
To properly manage security, it is very important to manage users and user
groups. You may set the share access parameters of each user or user group
accordingly.
53
· Quota
To allocate disk volume efficiently, you can specify the quota that can be used
by each user. When quota is set, users are not allowed to further use disk
space once they have reached their quota limit. By default, no limitations are
set for users. You can modify the following two options:
ü Enable quota for all users
ü Quota size on each disk volume
54
3.8 Network Share Management
The primary purpose of network storage is file sharing. In a standard operation
environment, you can create different network share folders for various types of
files, or provide different file access rights to users or user groups. By factory
