What is NAS? |
|
NAS (Network Attached Storage) is the term used to refer to storage elements that
connects to a network and provides file access services to computer systems. A NAS
storage element consists of an engine, which implements the file services, and one
or more devices on which data is stored. NAS may be attached to any type of network.

|
What is the difference between NAS and SAN?
|
|
Compared to NAS, SAN (Storage Area Network) is a network architecture whose primary
purpose is the transfer data between computer systems and storage elements, and among
storage elements.

NAStorage is specifically designed as a plug & play stand-alone server. It is
not necessary for you to install any additional server or any driver/software application
in your client PC. The only thing you have to do is "plug in the network cable and
power on NAStorage". Only a few simple steps have to be taken before you can access
data from NAStorage server.
1. Go to the web-based Admin Home page.
2. Go to "Volume" page to create volumes even folders.
3. Create a share for network share via "Security" page.
4. Assign appropriate permission to the shared volume or folder
|
|
|
|
Can the LCD panel be used to configure the NAStorage?
|
|
Yes, you can manipulate the LCD panel to make some basic settings
for the NAStorage such as "IP Address", "Subnet Mask", "Default Gateway", "Time/Date",
etc.
|
|
What are the advantages of having the LCD panel on NAStorage?
|
|
In addition to performing the basic settings on the LCD panel, the NAStorage will
report some of the system status onto the LCD panel such as CPU Temperature, Configuration,
Firmware Version, Event Status, etc. It is very convenient for the system administrator
to get the major system status without having to go into web-based administration
page
|
|
What will be the status of NAStorage if the option "Reset configuration to factory
default" within shutdown is invoked?
|
|
All the settings of NAStorage will be return to default value after it has been set
to " Reset configuration to factory default ", which are:
. Server settings: Notification level, LCD banner, Code Page, Schedule power-on/shutdown,
Administration password, Time Zone, etc.
. Network settings: IP relative settings, server/workgroup/domain names, security
mode, etc.
|
|
|
|
What are the default values of major NAStorage settings?
|
|
The default settings relative to first time installation are:
1. IP address: 192.168.1.1
2. Domain/Workgroup name: WorkGroup
3. Server name: NASxxxxxxxx
"xxxxxxxx" is the last 8-digit of the MAC address of the NAStorage controller. The
MAC address is found at the back of the tower.
|
|
What is to be done if the administration password of the NAStorage is forgotten?
|
|
NAStorage provides an option to clear the administration password. Please follow the
below mentioned steps to clear you password:
1. Shutdown and turn off the NAStorage.
2. Set the DIP switch located in the power connector of control board to 1:on, 2:on.
3. Power on the NAStorage till you see the message "Clear Password" displayed on the
LCD panel.
4. Turn off the NAStorage and set the DIPswitch back to 1:off, 2:off.
5. Turn on the NAStorage again, and you will see that the administration password
has been restored to factory default
|
|
|
|
How to use the "DIP switch" (S1) located on the NAStorage Control Board?
|
|
There are four modes to which the DIP switch can be set; you
also can set DIP switch to whether connect with hot swap HDD module (MR423I):
DIP1 and DIP2:
1. Normal Mode: (default setting) DIP1 =Off, DIP2 =Off.
2. Recovery Mode: DIP1 =On, DIP2 =Off.
3. Manufacture Mode: DIP1 =Off, DIP2 =On.
4. Clear Admin Password: DIP1 =On, DIP2 =On.
DIP3:
1. Connect with hot swap HDD module (MR423I) DIP3=Off
2. Connect without hot swap HDD module (MR423I) DIP3=On
Basically, the users can only access their NAStorage in the "Normal Mode". The "Recovery"
and "Manufacture" modes are only available for diagnostic purposes by the manufacturer;
and the normal user will not be able to access NAStorage under these two modes. In
addition, NAStorage will clear admin password to empty when the DIP switch is set
in the "Clear Admin Password". Please remember that you have to change the setting
back to "Normal Mode" before NAStorage boots at next time.

|
|
|
|
|
What is the minimum memory capacity requirement for NAStorage?
|
|
We strongly recommend at least 128MB memory (SDRAM) to be installed
in NAStorage for maintaining the basic functionality; that will also prevent the system
resources from being insufficient while performing some memory-consuming tasks.
|
|
|
|
|
|
How to use NAStorage "Network Recovery Mode"?
|
|
Please refer the Technical Guide - Administrator Guide - Network
Recovery Mode (pdf file).

|
|
How to differentiate IDE flat and round cables delivered with NAStorage and MR-423I
pack?
|
|
Blue round cable (part no: 5011.1402)--> connects with the MR-423I (hot swappable
rack) --> 2 cables are delivered with all MR-423I racks together with a I²C cable
(part no: 5044.16016) "4 wires + the 2 fixed connectors".
Green round cable (part no: 5011.14027)--> connects with the CD/DVD/tape devices
(5th IDE channel in the NAStorage controller)--> 1 cable delivered with the basic
NAStorage controller pack.
Yellow flat cable (part no: 5011.14025, 5011.14026)--> HDD's directly connected
with the NAStorage when they are not used with a MR-423I rack--> 4 flat yellow
cables delivered with the basic NAStorage controller pack.
Mixing the cables with the applications will cause malfunctioning of the NAStorage.
Please keep it in mind and be particularly aware of the fact that the NAStorage features
of hot swap and hot spare need imperatively the MR432I hot swappable rack. No other
exists on the market as special electronic circuitry has been added on its backplane
by our engineering team to function properly with the NAStorage controller's refer
the Technical Guide - Administrator Guide - Network Recovery Mode (pdf file).

|
|
When I use web browser (eg. Microsoft IE) with proxy enabled to manage NAStorage,
even to upgrade latest firmware. Why did the web browser show me like "The page cannot
be displayed"?
|
|
NAStorage management interface was designed through web browser.
Thus, when you want to set or modify some configurations, NAStorage has to get the
real-time information.
Here is the workaround for your reference:
1. Open the IE browser.
2. Select the Tools->Internet Options->Connections->LAN Settings.
3. Click the "Advanced" button.
4. Within the "Exceptions" item fill in the window with IP address of NAStorage.
5. Click "OK" to complete setting.
