How does the CF work in the embedded system with the Filer?

When the user has written our program into a CF and then inserted it into the embedded system, the system will read the initial data from CF in the first installation. After that, any system updates will also update the CF content accordingly.

What are the important issues when you install the NAS for the first time?

Suppose you want to set up a server called NAS001 for the first time. By default, the system obtains the network configuration information through the DHCP server. If the DHCP server exist on the LAN, its IP Status will show DHCP. This means the NAS server has correctly received an IP address from DHCP server. Please use your mouse to double click the server NAS001 or click the Manage button. Network Filer Plus Assistant will automatically invoke the browser and connect to the server’s IP address. Start the Quick Configuration option of Storage Manager for the system, which is where the administrator can setup basic information such as server and network groups and system access.
If there is no DHCP server on the LAN or the client that executes Network Filer Plus Assistant and the NAS server do not belong to the same subnet, the IP Status column will show Unknown.
DNS helps you find the IP address of a domain name. Be sure to input the correct DNS server in the field so that the Email notices from the system can reach the administrator’s mailbox.
Make sure the client terminal you are using has successfully installed and setup the TCP/IP protocol, and is running Microsoft Internet Explorer 5.0 or higher.

What should I be aware of when I move the NAS from one network environment to another?

Please make sure that the NAS has obtained the same IP address and that the Client and Server are both in the same subnet, otherwise, the client may not be able to connect with server.

What kind of configuration is required if I want to connect multiple Filers?

If a user wants to connect multiple Filers, the local intranet must have an IP SAN to allow the different Filers to communicate with each other through Internet Protocol. The Network Filer Plus will have iSCSI support in v1.2 where the user will be able to link different Filers through the Internet or TCP/IP.

Why can’t I setup the Network Filer Plus for the first-time?

Make sure you have selected the correct server.
Make sure the server is connected to the LAN.
Make sure the server is connected to a power source and both are turned on.
Make sure the LAN still has free IP addresses.
Make sure the manually entered network settings are correct.
Make sure the client terminal you are using is running Microsoft Internet Explorer 4.0 or higher.

Why can’t I boot-up the Filer?

There are two possibilities that could cause a system reboot failure:

If the system administrator has integrated the NAS server into an NIS domain, you will not be able to reboot the NAS server if the NIS server is not available. Please make sure the NIS server is available first and then restart the NAS server.
A hard disk error could also cause a system reboot failure. Please make sure all hard disks are functioning normally. If there is bad sector or bad track found on a hard disk, please replace the hard disk with a new one.  If you need a Great Garmin GPS Unit For Your Car then take a look at this website in more detail.

Do I need an extra File Server if I use the Network Filer Plus?

The Network Filer Plus provides an ease-of-use data sharing environment. Through a simple Peer-to-Peer structure, users need only the basic equipment to use the Network Filer Plus (for example: Cat 5 cable, Ethernet adapters, and an Ethernet hub or crossover cable). The Network Filer Plus provides shared storage space only. There are no built in print services, Internet gateways, or other functions provided on a full network file server.

Does the Network Filer Plus support both 110/220V power supplies?

Yes, the Network Filer Plus was originally designed to support both 110/220 voltages and 50/60 Hz line frequencies. When the power core is connected, the Filer will automatically detect the external voltage and frequency. As long as the power supply is standard, the Network Filer Plus will support it.

How much data is a Network Filer Plus able to store?

It depends on the HDD size and the particular RAID level that user has chosen. For example, if using RAID 0 and there are 8 160GB HDDs installed, the maximum data the Filer will be able to store is 160×8=1280GB. However, there is a size limitation for a single volume (1 TB) and that means the RAID 0 volume would only be able to carry 960GB.

Does the Network Filer Plus support the use of UPS systems?

Currently the UPS support is based on the selection of partnerships (for example, APC is one partner and we support their UPS). After users logon to the Filer, choose Toolkit->UPS Management to enter the UPS configuration page to control settings such as: preset detect period, delay time, UPS message control, battery status, etc.

Can I make a separate partition on a HDD that will be installed in a Network Filer Plus?

All HDDs installed in the Filer will be accumulated based on its actual size. Any pre-partitioned HDDs will not be able to be part of the system. However, users could manage the disk space through Volume creation and Share Folder control, which provides increased flexibility.

What is the maximum number of HDDs and volumes supported by the Filer?

Due to Hardware limits, the Filer is able to support up to 8 HDDs and the maximum number of volumes allowed is calculated as: (number of HDDs) x 1.5, which has an upper limit of 12 volumes. However, the Filer may display an error message when the system does not have enough Buffers, which may slightly lower the maximums.

Are there any HDD compatibility issues with the Network Filer Plus?

NAS has used the most advanced data processing techniques and was able to double the processing speed from an original 24 bits to 48 bits. As long as the hardware structure is defined, NAS will be able to support it with no further changes to its Spec.

What are the reserved system Account, Group and Share names?

The 12 reserved Account names are: Root, Guest, Bin, Bind, Daemon, Kmem, Nobody, Operator, Pop, Tty, Uucp, Xten.
The 18 reserved Group names are: Admins, Guests, Users, Bin, Bind, Daemon, Dialer, Kmem, Mail, Network, Nobody, Nogroup, Operator, Sys, Tty, Uucp, Wheel, Xten.
The 3 reserved Share names are: Global, Homes, PublicX (where X=1,2,3…….)

Why is the System Administrator allowed to set “0”as a user quota during Security setup?

Check if the network settings of the NAS server are correct and make sure that the IP of the NAS server does not conflict with those of other servers on the LAN.
Make sure the Windows client has correctly installed/set up TCP/IP.
Make sure the NAS server and the client computer that runs Microsoft IE can be connected through physical network medium (e.g. hub, switch, etc.) and in the same subnet.
Make sure that the browser is IE 5.0 or above and it can connect to other servers in the network.
Try typing the server name of the NAS server in the address field of IE.
Try typing the IP address of the NAS server in the address field of IE.
Try restoring the IE settings to defaults and try again.
Try restarting the server.

What does the “Netgroup” column do in the “NFS Privilege” settings page?

When a user is configuring the “NFS Privilege” settings, please make sure the particular machine has created the Netgroup on the NIS Domain. By doing this, the user will be able to see the “Netgroup”column on the “NFS Privilege” settings page. If the user does not see the “Netgroup” column, it is because the column is not required and “hidden” to avoid user confusion.

Is there any other way to enter the system administration page if the administrator has forgotten the ID & Password?

If system administrator forgets his/her ID and Password, re-installation and picking a new ID and Password is the only way to access the NAS again. For security issue, the Network Filer Plus does not allow the administrator to restore his/her ID and Password.

When the NAS is going to reboot, is there any alert sent to the user?

Under normal circumstances, the system will trigger an alert message email to all users when the system is going to close. However, if the administrator did the shut down manually, the system will be offline in just a few seconds and all user connections will be terminated.

Is there a size limitation on the NASsolution OS?

Theoretically there is no size limitation on the Network Filer Plus . However, most existing File Systems have there own limits for a single volume. (For example, the WINDOWS File System has a maximum of 1 TB that can be stored in a single volume.) As long as the user creates the volume in compliance with size allowances of the chosen File System, the Network Filer Plus will be able to support it.

How does using an ACL benefit the Network Filer Plus ?

With ACL support enabled, the Network Filer Plus can help increase security as it operates by allowing selective use of services. An Access Control List is the usual means by which access to, and denial of , services is controlled. It is simply a list of services available and the associated hosts permitted to use the service. As such, the System Administrator can control all available services and assigned the access rights to meet user requirements.

Why can’t the user’s account on the local machine connect to the Storage Manager?

The possible reasons include:

The account was originally a Windows PDC account. Please make sure the system administrator did not setup a password when adding it to the local accounts.
If the client platform is using a language different from the one used on the Storage Manager, the client might be reading random codes when using the system. The system administrator has to re-set the languages on the Storage Manager so that they are readable by the client.
The user may not be able to launch the Storage Manager via the Network Filer Plus Assistant if he has installed a browser other than IE (e.g. Netscape) and uninstalled it. We suggest that you use a computer that has not had a browser installed and then uninstalled.

Does a Network Filer Plus require local administration or software?

Not necessary. A Network Filer Plus only requires a console with basic input and output to perform all setup and administration. All the system related configuration and setting could be done remotely, no extra terminal or human resources are needed.

Why do square boxes appear on the Security Access page?

When using version 4.05 of the Netscape Navigator on an Apple Macintosh computer, some spaces appear as square boxes on the Security share access page. (This has no effect on functionality) NAS recommends that you upgrade your Web browser to either Netscape Communicator (Version 4.0 or higher) or Microsoft Internet Explorer (Version 4.0 or higher).

Why do I get the same configuration page even after I’ve updated it?

If your web browser is one of the older ones (below version 4.0), the browser may fail to refresh Network Filer Plus Web configuration pages. NAS recommends that you upgrade your Web browser to either Netscape Communicator (Version 4.0 or higher) or Microsoft Internet Explorer (Version 4.0 or higher).

When creating Groups, what are the setup concerns?

There are several point to be addressed when a user is creating a group:Group names are not case sensitive and can contain letters, numbers, dots, underscores and the minus sign. Other than that, all particular signs and spaces are not allowed to be part of the group name. The length cannot exceed 15 letters and the first character must be a letter, number, dot or underscore.

Why can’t I connect to the Filer from Linux? Is there any configuration that needs to be done?

Every RedHat Linux platform after version 6.3 has an extra Firewall installed. The Firewall is set to block all Internet activities. When finished the installation, please go to the Linux Console and do the following: key in ”Setup”->system configuration page->”Firewall Configuration”. You will now be able to setup the Access level of the Firewall. You should enter ”Customize” to adjust the allowed Connection Type for the access level and will now be able to connect the Filer.

Why can’t I connect to the server on a UNIX platform?

Please make sure your system has all the network settings configured correctly, especially the DNS and DHCP settings. Also log on to the Filer Assistant and make sure the Server Name, Domain Name, and DNS Server have been correctly specified, see the “Server Configuration-> Basic Configuration”page. Next, make sure LAN 1 and LAN 2 are accurately setup and if all these steps are completed, you should be able to connect to the server without any problems.

Why does the Filer sometimes fail to load images when I shift from page to page?

When using an older version browser to browse, you may sometimes notice that a page from the Network Filer Plus Web-based Administration utility loads only the text, using generic icons in place of the images that would normally appear. This will happen more often with versions of the MacOS prior to 8.0. Our testing indicates that this is caused by running too many programs simultaneously, especially those applications which are dealing with Multimedia or Graphic files. Quitting one or more programs is likely to resolve this issue.

Why can’t I open a Mac file that has been moved by a PC?

Mac files have both data and resource forks. The resource fork is the part of the file that indicates which application created it, and other information the Mac needs to be able to open the file. A PC system does not understand these resource forks so if you move an individual file created by a Mac with a PC, the resource fork is not moved with it making the file inaccessible from a Mac. If you move an entire subdirectory created with a Mac using a PC, then the resource forks for the files are preserved due to a difference in how the OS interprets the command to move everything instead of a single file. Please read the Release Notes for any additional information on Mac support.

When using Windows, why does the Filer displays a total capacity of only 2GB when I have actually have 20GB?

Some Windows 95 and 98 clients are unable to recognize free space in excess of 2 gigabytes due to a protocol limitation. For example, some clients will show 2 gigabytes of free space on a newly formatted 10-gigabyteNetwork Filer Plus . This occurs both with Microsoft networking and Novell networking, however is only an error in the display of the free space. All clients can still use all the available disk space (10 gigabytes in the previous example). Use the Network Filer Plus Web based administrator utility if you need to determine how much free space you have on a drive. This information is displayed on the View Disk Status page. Microsoft has documented this issue as a problem with their OS in the Microsoft Knowledge Base.

What is the function of the Data Replicator?

To provide tag management functions, tagging the most recent version and saving up to twenty tags that allow users to have version control.
Monitor file folders of Windows clients and perform immediate backups of selected folders to the Network Filer Plus when changes are made.
If a user constantly changed very large file, the automatic backup feature could cause the system to become overloaded. Users can ignore the monitor function and backup those files manually in order to gain system effectiveness.
Users can apply File Filtering to ignore certain files (for example, .bkp files for Windows clients). For more information on Truck GPS Units see this website.

Why am I not able to delete certain files from the NAS?

For Windows clients, if the administrator sets a single-byte language (code page) such as English or Multilingual, an error will occur when the client attempts to save double-byte files or folder names (e.g. Traditional Chinese) on the NAS server. Once saved, some of these files will not be able to be deleted. In this case, the system administrator must use the Server Configuration->Language Setup to change the code page to double-byte encoding, only then can the files be properly accessed and deleted.

What happens when a disk drive fails?

In a non-RAID system there are no inherent safety measures, if any hard disk (except the primary one) is damaged, all data in that hard disk will be lost. You will have to shut down the server, remove the hard disk, replace it with a new one, and reboot. The system will register this hard disk as a new non-RAID hard disk. If the primary hard disk fails, the system will not be able to boot and you will need to send the server back to the manufacturer for repairs. All the data on the server will probably be lost.

In a RAID 0 system, the system will fail completely if one hard disk is damaged. Again, you will have to send the system back for repairs and all the data will be lost.

In a RAID 1 or RAID 5 system, the failure of any hard disk in the system will be reported on the Storage Manager’s System Information Status page. A notification will be sent to the system administrator, who will only need to remove the broken disk (without having to power down the system), and replace it with a new one. The system will automatically restore the data on the new hard disk and client access will not be compromised during the rebuild phase.

What should I do when E-mail notifications not received?

If you don’t receive e-mail notifications from the server, go to the Storage Manager, System Information?log?System Log, and check the messages in the log. The following error messages refers to undelivered mail notifications:

Cannot resolve the host address:XXXXXX,Error Code:XXX
This message indicates that the DNS server could not verify the SMTP server name you provided. This may be due to one of the following reasons: DNS entry error, DNS server powered down, incorrect domain name, and incorrect SMTP server.
Cannot connect to host:XXX (xxx.xxx.xxx.xxx)
This message indicates that the system could not connect to the SMTP server, the possible reasons are: the network connection is broken, the SMTP server is unavailable, or the SMTP server rejected the message. Please contact the System Administrator or change your mailing path to the reserve mail server.
Mail server connection failed
This message indicates that the SMTP server has timed out and did not responded within 30 seconds. Verify that the SMTP server is working properly.
Send mail error:XXX
This message indicates an unknown mail error. Note the error code and contact the system manufacturer’s representative.
Cannot create socket resource
This message indicates that the system has insufficient resources to execute the mail send operation. Reboot the server to correct the problem.

What should I do when a client fails to access the NAS server?

If a Windows/UNIX/Novell/Apple client cannot access the server, please confirm the following:

Check to see if the Network Setup in the Storage Manager is correctly configured.
If the NAS server has been added to a UNIX NIS domain, please confirm that the UNIX NIS server is still functioning normally.
Check to see if there are any hosts on the network using the same IP or server name as the NAS server. If there are, correct the situation as soon as possible.
When a Windows 2000 client cannot access privileged files, it could be because the client was logged in as a guest due to the wrong account name being entered when logging on to the NAS server. Please log out of the server and log in again.
Network Filer Plus will only allow a maximum of 512 clients to log onto the network at the same time. Users may have to wait a moment before trying to reconnect.
If users have added the NAS server into a Windows domain, please check that the Windows PDC is operating normally and the NAS server account still exists in the PDC. The system administrator can try to recreate the NAS server account in PDC and add the server into the Windows domain in Storage Manager.
If all the above settings are correct, please reboot the NAS server.

Why I cannot use Internet Explorer to connect to NAS Server?

Check if the network settings of the NAS server are correct and make sure that the IP of the NAS server does not conflict with those of other servers on the LAN.
Make sure the Windows client has correctly installed/set up TCP/IP.
Make sure the NAS server and the client computer that runs Microsoft IE can be connected through physical network medium (e.g. hub, switch, etc.) and in the same subnet.
Make sure that the browser is IE 5.0 or above and it can connect to other servers in the network.
Try typing the server name of the NAS server in the address field of IE.
Try typing the IP address of the NAS server in the address field of IE.
Try restoring the IE settings to defaults and try again.
Try restarting the server.

What is iSCSI?

iSCSI is a young technology that promises simpler networks and lower costs because it’s based on the much more common Internet Protocol (IP). The key to this technology is the ability to speed up IP—specifically, the TCP/IP processing that packages data to be sent on the network. It supports Windows, Linux, Apple, and Novell platforms and has a lower cost than its rival – SAN. SAN is used with high-end networking equipment based on Fiber Channel, an expensive and complicated but functioning and improving networking standard. To a certain extent, the two technologies are appropriate for different uses but because fundamentally they do the same job, hardware and software makers as well as customers must bet one way or the other or accommodate both.  See more information here.

What is the JFS (Journaling File System)?

Most modern File Systems use journaling techniques borrowed from the database world to improve crash recovery. Disk transactions are written sequentially to an area of disk called the journal or log before being written to their final locations within the File System.
Implementations vary in terms of what data is written to the log. Some implementations write only the File System metadata, while others record all writes to the journal.

What is File Locking? Is the Network Filer Plus able to support File Locking?

File Locking is a file level security mechanism which bans the access rights for unauthorized users preventing them from accessing files. The current Filer version can only control share level security and will have similar functions at the file level in the next release.

What is NAS(Network Attached Storage)?

This refers to storage (usually disk but possibly tapes or memory) attached to and distributed (shared) over a network. Usually the environment of a NAS is such that many computers share a lot of data in order to increase security while reducing maintenance and data management costs.

What is File Fragmentation?

When you save a file to your hard disk, the operating system will try and store the complete content of the file to the same section of the hard disk. When the disk starts to become full, this goal becomes impossible to achieve and the operating system splits the contents of the file over different section of the disk. The file become fragmented and we call this File Fragmentation. When a user tries to access this file, an extra process is needed in order to gather the file fragments and join them to form the complete file.

What is Storage Over IP?

Storage over IP uses the mainly standardized IP-Base protocol to connect to different storage devices and allow those devices to run under DAS, NAS, or SAN Infrastructures. The management of the network storage systems will allow the user to use End-to-End, Virtualization or Aggregation.

What are the benefits of NDMP (Network Data Management Protocol)?

With NDMP, network congestion is minimized because the data path and control path are separated. Backups can occur locally from the file server directly to the tape drives, while management can occur from a centralized location. Furthermore, NDMP is an open-standard protocol promoted and supported by Server vendors, Backup software vendors, and Backup device vendors.

What is a SAN Gateway?

A SAN is a high performance and dedicated network storage subsystem that is connected to the backend of a server. A SAN Gateway liberates the devices, so they are not on any one particular server bus, and attaches them directly to the system network via network processors. The result is that SAN architecture makes all storage devices accessible to all servers on the network. However, to build up a SAN requires that Fiber Channel be used as the main structure, effectively making the cost considerably expensive. Regardless, many people believe that the SAN will become the standard Enterprise-wide network storage solution.

What is NIS?

NIS is one of the Client/Server protocols developed by Sun Microsystems and is also referred to as Yellow Pages (YP). UNIX administrators to manage databases that are distributed across a network commonly use this service. Sun Microsystems authorizes this protocol to almost all the Unix system developers.

What are the differences between the Network Filer Plus and other existing products?

The Network Filer Plus supports IDE HDD HOT SWAP.
The Network Filer Plus supports Multi-languages.
The Network Filer Plus supports RAID HOT SPARE in order to achieve on-line data re-building and avoid system Down Time.
The Network Filer Plus supports Network Trunking and Failover. When one of the Ethernet cards is down, the system will enable the backup Ethernet card to avoid disconnection.
The Network Filer Plus offers cross platform support. (Windows/UNIX/Apple/Novell…..etc.)
The Network Filer Plus supports all RAID and non-RAID standards.

What does RAID mean?

RAID is the abbreviation of the acronym “Redundant Array of Independent Disks”. A grouping of standard disk drives together with a RAID controller is used to create a storage device that acts as one disk to provide performance beyond that available from an individual disk. Primarily designed for operation with computers, RAID can offer very high capacity, fast data transfer rates, and much-increased security of data. The latter is achieved through disk redundancy so that disk errors or failures can be detected and corrected.
